Especially in the construction of rivers, ports, seas, etc., blasting methods are often required to remove obstacles to ensure the dredging of waterways and navigation safety. During the blasting construction process, precise control is required to avoid unnecessary damage to the surrounding environment and facilities.

[0006] In the existing blasting construction control methods, the control of blasting construction is usually directly achieved through blasting monitoring devices. However, there is a possibility that the blasting monitoring devices based on this have insufficient monitoring accuracy, making it difficult to accurately control the blasting effect in real time, resulting in problems such as over-blasting, resource waste or insufficient blasting. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a precise control method and system for blasting construction, which can effectively solve the problems involved in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: In the first aspect of the present invention, a precise control method for blasting construction is provided, including: S1.

[0020] The explosive blasting speed ratio, the blasting vibration ratio, the blasting energy deviation value, the blasting action radius deviation value of each blasting device, and the maximum blasting delay duration of each blasting device in the historical blasting cycle are comprehensively analyzed to obtain the blasting precision performance indexes of each blasting device. The blasting precision performance indexes of each blasting device are used to comprehensively quantify the precision performance of each blasting device in the blasting operation.

[0021] As a further method, it is determined whether each blasting device can carry out blasting construction according to the device precision performance comparison result. The specific determination process is as follows:

[0023] If the blasting precision performance index of a certain blasting device is less than the threshold value of the blasting precision performance index of the blasting device preset in the blasting database, the device precision performance comparison result is recorded as the second precision performance comparison result.

[0024] If the device precision performance comparison result is the first precision performance comparison result, the blasting device can perform blasting construction, and several blasting devices capable of performing blasting construction are recorded as each precision blasting equipment.

[0025] As a further method, the specific analysis process of the blasting construction precision control index is as follows:

[0026] The dynamic data of the blasting construction test in the blasting test process specifically includes the total amount of explosives used in the blasting construction within the blasting test cycle, the real-time blasting vibration acceleration, the real-time blasting vibration rate, and the real-time blasting vibration frequency.

[0031] As a further method, it is determined whether precise control of the blasting construction is required according to the precise comparison result of the blasting construction. The specific determination process is as follows:

[0032] If the precise control index of the blasting construction is equal to the defined value of the precise control index of the blasting construction preset in the blasting database, the precise comparison result of the blasting construction is recorded as the first precise comparison result of the blasting construction.

[0033] If the precise control index of the blasting construction is greater than the defined value of the precise control index of the blasting construction preset in the blasting database, the precise comparison result of the blasting construction is recorded as the second precise comparison result of the blasting construction.

[0034] If the precise control index of the blasting construction is less than the defined value of the precise control index of the blasting construction preset in the blasting database, the precise comparison result of the blasting construction is recorded as the third precise comparison result of the blasting construction.

[0035] If the precise comparison result of the blasting construction is the second precise comparison result of the blasting construction or the precise comparison result of the blasting construction is the third precise comparison result of the blasting construction, precise control of the blasting construction is required.

[0036] The second aspect of the present invention provides a precise control system for blasting construction, including: a blasting construction area evaluation module, configured to obtain environmental data of the pre-blasting construction area, analyze to obtain a blasting construction environmental impact index, and compare it with the threshold value of the blasting construction environmental impact index preset in the blasting database to obtain an environmental impact comparison result, and determine whether blasting construction can be carried out in the pre-blasting construction area according to the environmental impact comparison result; a blasting device detection module, configured to, if the blasting construction environmental impact index is less than the threshold value of the blasting construction environmental impact index preset in the blasting database, record the pre-blasting construction area as a blastable area, match the blasting construction environmental impact index with the reference precise performance data of the blasting device corresponding to each blasting construction environmental impact index interval preset in the blasting database to obtain the reference precise performance data of the blasting device corresponding to the pre-blasting construction area, obtain the precise performance data of each blasting device, and comprehensively analyze it with the reference precise performance data of the blasting device to obtain the blasting precise performance index of each blasting device, and compare it with the threshold value of the blasting precise performance index of the blasting device preset in the blasting database to obtain a device precise performance comparison result, and determine whether each blasting device can carry out blasting construction according to the device precise performance comparison result; a blasting construction test module, configured to carry out a blasting construction test in the blastable area, obtain the dynamic data of the blasting construction test during the blasting test, analyze to obtain a blasting construction precise control index, and compare it with the defined value of the blasting construction precise control index preset in the blasting database to obtain a blasting construction precise comparison result, and finally determine whether precise control of the blasting construction is required according to the blasting construction precise comparison result.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Referring to Figure 1 As shown, the first aspect of the present invention provides a precise control method for blasting construction, including: S1. Blasting construction area assessment: Obtain the environmental data of the pre-blasting construction area, analyze to obtain the blasting construction environmental impact index, compare it with the preset blasting construction environmental impact index threshold in the blasting database, obtain the environmental impact comparison result, and determine whether blasting construction can be carried out in the pre-blasting construction area according to the environmental impact comparison result.

[0046] S2. Blasting device detection: When the blasting construction environmental impact index is less than the preset blasting construction environmental impact index threshold in the blasting database, the pre-blasting construction area is recorded as a blastable area, match the blasting construction environmental impact index with the reference precise performance data of the blasting device corresponding to each preset blasting construction environmental impact index interval in the blasting database to obtain the reference precise performance data of the blasting device corresponding to the pre-blasting construction area, obtain the precise performance data of each blasting device, and conduct comprehensive analysis with the reference precise performance data of the blasting device to obtain the blasting precise performance index of each blasting device. Compare it with the preset blasting device blasting precise performance index threshold in the blasting database to obtain the device precise performance comparison result, and determine whether the blasting device can carry out blasting construction according to the device precise performance comparison result.

[0047] In this embodiment, each blasting device includes, but is not limited to, explosive devices, initiation devices, blasting monitoring systems such as seismic wave monitors, vibration monitoring systems, pressure sensors, etc., blasting control systems, control errors, system response speeds, etc., and drilling devices.

[0048] S3. Blasting construction test: Conduct a blasting construction test in the blastable area, obtain the dynamic data of the blasting construction test during the blasting test, analyze to obtain the precise control index of the blasting construction, compare it with the preset precise control index definition value of the blasting construction in the blasting database to obtain the precise comparison result of the blasting construction, and finally determine whether precise control of the blasting construction is required according to the precise comparison result of the blasting construction.

[0049] Specifically, the environmental data of the pre-blasting construction area specifically includes the average compressive strength of the rock formation, the average density of the rock formation, the average compressive strength of the soil, the average density of the soil, the average depth of the groundwater level in the pre-blasting construction area during the environmental monitoring period, and the real-time environmental temperature.

[0050] It should be noted that the above-mentioned average compressive strength of the rock stratum is obtained by selecting several rock stratum samples in the pre-blasting construction area, testing them according to the uniaxial compression test method, placing the rock stratum samples on a pressure testing machine, and applying a gradually increasing pressure along its axis until the samples are damaged. Record the maximum pressure when the samples are damaged, add up the pressure strength values of all the samples, and then divide by the number of samples to obtain the average compressive strength of the rock stratum. When selecting rock stratum samples, a densitometer can be used to measure the density of the rock stratum samples. By averaging the measurement results of multiple samples, the average density of the rock stratum can be obtained. The method for obtaining the average compressive strength of the soil is similar to that of the rock stratum compressive strength. In the pre-blasting construction area, several soil samples are selected and tested according to the uniaxial compression test method. Add up the pressure strength values of all the samples and then divide by the number of samples to obtain the average compressive strength of the soil. The average density of the soil can be obtained by using a densitometer to measure the density of multiple soil samples and calculating the average value. The average depth of the groundwater level is obtained through a groundwater level monitoring system, which usually includes a groundwater level gauge, data transmission equipment, a monitoring center, etc. The groundwater level gauge is arranged in the pre-blasting construction area, and the real-time data is transmitted to the monitoring center through the data transmission equipment, so as to obtain the change of the groundwater level. By averaging the groundwater level data within the environmental monitoring period, the average depth of the groundwater level can be obtained. The real-time environmental temperature is obtained by arranging a thermometer in the pre-blasting construction area to monitor the change of the environmental temperature in real time. In this embodiment, the environmental monitoring period refers to the time interval for monitoring the environmental data in the pre-blasting construction area, and the specific environmental monitoring period is randomly arranged according to the blasting construction plan and the environmental changes in the blasting area.

[0051] In this embodiment, there is a certain mutual influence among the average compressive strength of the rock stratum, the average density of the rock stratum, the average compressive strength of the soil, the average density of the soil, the average depth of the groundwater level in the pre-blasting construction area within the environmental monitoring period, and the real-time environmental temperature. The average compressive strength of the rock stratum and the average density of the rock stratum are usually positively correlated. Rock strata with a larger density often contain more minerals and a denser structure, thus having a higher compressive strength. A similar relationship also exists between the average compressive strength of the soil and the average density of the soil. A dense soil structure usually means a higher compressive strength. The compressive strength and density of the rock stratum will affect the flow path of groundwater and the change of the water level. The depth of the groundwater level will affect the difficulty and safety of the blasting construction. If the groundwater level is relatively high, it will increase the risk of water shock waves during blasting, and may also cause water accumulation in the cracks or cavities generated after blasting, affecting subsequent construction. The increase in environmental temperature will cause an increase in the thermal stress inside the rock stratum and soil, thus affecting their compressive strength.

[0052] The average compressive strength of the rock stratum, the average density of the rock stratum, the average compressive strength of the soil, the average density of the soil, and the average depth of the groundwater level in the pre-blasting construction area are respectively processed by taking ratios with the allowable compressive strength of the rock stratum, the allowable density of the rock stratum, the allowable compressive strength of the soil, the allowable density of the soil, and the reference depth of the groundwater level preset in the blasting control database, to obtain the rock stratum compressive strength ratio, the rock stratum density ratio, the soil compressive strength ratio, the soil density ratio, and the groundwater level depth ratio in the pre-blasting construction area.

[0053] Specifically, for the blasting construction environment impact index, the specific analysis process is as follows:

[0054] The real-time environmental temperature in the pre-blasting construction area during the environmental monitoring period is processed by taking the difference with the reference environmental temperature preset in the blasting control database, to obtain the real-time environmental temperature difference in the pre-blasting construction area during the environmental monitoring period.

[0055] The rock stratum compressive strength ratio, the rock stratum density ratio, the soil compressive strength ratio, the soil density ratio, the groundwater level depth ratio in the pre-blasting construction area, and the real-time environmental temperature difference in the blasting construction area during the environmental monitoring period are comprehensively analyzed to obtain the blasting construction environment impact index, and the blasting construction environment impact index is used to comprehensively quantify the potential impact degree of the environment in the blasting construction area on the blasting construction.

[0056] The specific analysis method for the blasting construction environment impact index is as follows:

[0057]

[0058] In the formula, CE is the blasting construction environment impact index, e is the natural constant, yq is the rock stratum compressive strength ratio, c1 is the impact factor corresponding to the unit value of the rock stratum compressive strength ratio preset in the blasting database, ym is the rock stratum density ratio, c2 is the impact factor corresponding to the unit value of the rock stratum density ratio preset in the blasting database, ty is the soil compressive strength ratio, c3 is the impact factor corresponding to the unit value of the soil compressive strength ratio preset in the blasting database, tm is the soil density ratio, c4 is the impact factor corresponding to the unit value of the soil density ratio preset in the blasting database, sd is the groundwater level depth ratio, c5 is the impact factor corresponding to the unit value of the groundwater level depth ratio preset in the blasting database, wd is the real-time environmental temperature difference at time point v in the blasting construction area during the environmental monitoring period, v0 is the starting time point of the environmental monitoring period, v1 is the ending time point of the environmental monitoring period, v is any time point within the environmental monitoring period, v ∈ [v0, v1], and c6 is the impact factor corresponding to the unit value of the real-time environmental temperature difference preset in the blasting database.

[0059] It should be explained that the above-mentioned rock compressive strength ratio refers to the ratio between the average compressive strength of the rock strata in the pre-blasting construction area and the allowable compressive strength of the rock strata preset in the blasting control database; the rock density ratio refers to the ratio between the average density of the rock strata and the allowable density of the rock strata preset in the blasting control database; the soil compressive strength ratio refers to the ratio between the average compressive strength of the soil and the allowable compressive strength of the soil preset in the blasting control database; the soil density ratio refers to the ratio between the average density of the soil and the allowable density of the soil preset in the blasting control database; the underground water level depth ratio refers to the ratio between the average water level depth and the reference depth of the underground water level preset in the blasting control database; the real-time environmental temperature difference refers to the difference between the real-time environmental temperature in the pre-blasting construction area during the environmental monitoring period and the reference environmental temperature preset in the blasting control database; any time point within the environmental monitoring period refers to any specific moment in the monitoring period during environmental monitoring.

[0060] In this embodiment, the influence factor corresponding to the unit value of the rock compressive strength ratio preset in the blasting database represents the influence degree of the unit value of the rock compressive strength ratio on the blasting construction environment impact index. The corresponding relationship between the unit value of the rock compressive strength ratio and its corresponding influence factor is stored in the blasting database. For example, when the unit value of the rock compressive strength ratio is input into the blasting database, the blasting database can match the influence factor corresponding to the unit value of the rock compressive strength ratio; the influence factor corresponding to the unit value of the rock density ratio preset in the blasting database represents the influence degree of the unit value of the rock density ratio on the blasting construction environment impact index. The corresponding relationship between the unit value of the rock density ratio and its corresponding influence factor is stored in the blasting database. For example, when the unit value of the rock density ratio is input into the blasting database, the blasting database can match the influence factor corresponding to the unit value of the rock density ratio; the influence factor corresponding to the unit value of the soil compressive strength ratio preset in the blasting database represents the influence degree of the unit value of the soil compressive strength ratio on the blasting construction environment impact index. The corresponding relationship between the unit value of the soil compressive strength ratio and its corresponding influence factor is stored in the blasting database. For example, when the unit value of the soil compressive strength ratio is input into the blasting database, the blasting database can match the influence factor corresponding to the unit value of the soil compressive strength ratio; the influence factor corresponding to the unit value of the soil density ratio preset in the blasting database represents the influence degree of the unit value of the soil density ratio on the blasting construction environment impact index. The corresponding relationship between the unit value of the soil density ratio and its corresponding influence factor is stored in the blasting database. For example, when the unit value of the soil density ratio is input into the blasting database, the blasting database can match the influence factor corresponding to the unit value of the soil density ratio; the influence factor corresponding to the unit value of the underground water level depth ratio preset in the blasting database represents the influence degree of the underground water level depth ratio on the blasting construction environment impact index. The corresponding relationship between the underground water level depth ratio and its corresponding influence factor is stored in the blasting database. For example, when the underground water level depth ratio is input into the blasting database, the blasting database can match the influence factor corresponding to the underground water level depth ratio; the influence factor corresponding to the unit value of the real-time environmental temperature difference preset in the blasting database represents the influence degree of the unit value of the real-time environmental temperature difference on the blasting construction environment impact index. The corresponding relationship between the unit value of the real-time environmental temperature difference and its corresponding influence factor is stored in the blasting database. For example, when the unit value of the real-time environmental temperature difference is input into the blasting database, the blasting database can match the influence factor corresponding to the unit value of the real-time environmental temperature difference.

[0061] In this embodiment, the greater the uniaxial compressive strength of the rock stratum, the more difficult it is to break the rock stratum by blasting, which may lead to the need for more explosives or more intense blasting to achieve the expected construction effect. This not only increases the construction cost but also may exacerbate the damage to the surrounding environment, such as increasing the risks of vibration, flying rocks, etc., thereby increasing the blasting construction environmental impact index; the greater the density of the rock stratum, the higher its mass and stability usually are, which will also increase the difficulty of blasting. The high-density rock stratum may absorb more blasting energy, resulting in poor blasting effect; the greater the uniaxial compressive strength of the soil, the more difficult the blasting construction will be. This may lead to incomplete fragmentation of the soil after blasting, affecting subsequent construction and may increase the risk of damage to surface and underground structures; the high-density soil will also absorb more blasting energy, reducing the blasting efficiency; when the groundwater level is high, the vibration and shock waves generated by blasting may be more easily transmitted into the groundwater, causing water body disturbance. At the same time, the high water level may also increase the permeability of the soil and rock stratum after blasting, leading to further changes in the groundwater level and potential threats to the surrounding environment; when the environmental temperature difference is large, it may cause changes in the performance of blasting materials (such as explosives), affecting their blasting effect. In addition, the temperature difference may also affect the physical properties of the soil and rock stratum, such as thermal expansion and contraction, etc., thereby increasing the uncertainty of blasting construction and the impact on the surrounding environment; therefore, through the detailed analysis of each parameter in the blasting construction environmental impact index, the impact degree of blasting construction on the surrounding environment can be more accurately evaluated, providing a scientific basis for the formulation of construction plans.

[0062] Further, it is determined whether blasting construction can be carried out in the pre-blasting construction area according to the environmental impact comparison result. The specific determination process is as follows:

[0063] In this embodiment, the blasting construction environmental impact index is compared with the threshold value of the blasting construction environmental impact index preset in the blasting database; if the blasting construction environmental impact index is greater than or equal to the threshold value of the blasting construction environmental impact index preset in the blasting database, the environmental impact comparison result is recorded as the first environmental impact comparison result.

[0064] It should be explained that when the blasting construction environmental impact index is greater than or equal to the threshold value of the blasting construction environmental impact index preset in the blasting database, it means that the impact degree of the current pre-blasting construction area environment has reached or exceeded the predetermined standard in terms of safety. Blasting construction will have great difficulties and will also cause greater negative impacts on the surrounding environment, safety or other factors, and further control measures or evaluations may be required. Therefore, the environmental impact in this case is considered to be relatively high and is marked as the "first environmental impact comparison result".

[0065] If the blasting construction environmental impact index is less than the threshold value of the blasting construction environmental impact index preset in the blasting database, the environmental impact comparison result is recorded as the second environmental impact comparison result.

[0066] It should be explained that when the blasting construction environment impact index is less than the threshold value of the blasting construction environment impact index preset in the blasting database, it means that the environmental impact degree of the current pre-blasting construction area is below the preset standard, indicating that the construction has a relatively small impact on the environment and meets the normal safety standards. In this case, the impact of the construction environment on the surrounding environment is considered to be low and can be regarded as the "second environmental impact comparison result".

[0067] If the environmental impact comparison result is the second environmental impact comparison result, then blasting construction can be carried out in the pre-blasting construction area, and the pre-blasting construction area is recorded as a blastable area.

[0068] If the environmental impact comparison result is the first environmental impact comparison result, a warning signal for the blasting construction area needs to be sent to the blasting construction control platform.

[0069] In this embodiment, the blasting construction control platform is a management platform used to monitor and manage various parameters, environmental impacts, and safety warnings during the blasting construction process in real time. This platform will integrate multiple sensors and data sources to obtain the environmental information, blasting data, and construction impact index of the construction site in real time, and make warnings or adjust the construction plan based on this information to ensure the safety of the blasting construction; the purpose of sending the warning signal for the blasting construction area is to remind relevant personnel (such as construction workers, safety monitoring personnel, environmental protection departments, etc.) to take precautions or measures when the blasting construction environment impact index is relatively high. The role of this signal is to ensure a timely response to potential risks and avoid causing greater threats to the surrounding environment or personnel safety. The warning signal can trigger various safety measures, such as stopping construction, evacuating personnel, and checking the implementation of environmental protection measures.

[0070] Specifically, the precise performance data of each blasting device specifically includes the maximum blasting delay duration, average mass of blasting explosives, average energy density of blasting explosives, average radius of blasting action, average blasting speed of explosives, and average blasting vibration of each blasting device during the historical blasting cycle.

[0071] It should be noted that the maximum blasting delay duration of each of the above blasting devices within the historical blasting cycle is obtained by referring to the historical blasting records of each blasting device, finding the delay settings and actual initiation times for each blasting, comparing the delay data for different blasting cycles, and identifying the maximum blasting delay duration; the average mass of the blasting explosives is the total amount of explosives used in each blasting counted and the average value of the total amount of explosives calculated; the average energy density of the blasting explosives can be obtained by referring to the energy density data of the explosives in the technical materials provided by the explosives manufacturer; the average blasting action radius can be obtained by referring to the measurement data in the historical records, obtaining the action radius of each blasting, and calculating the average value of the action radii of multiple blastings to get the average blasting action radius; the average blasting velocity of the explosives is measured at the historical blasting site using a blast velocity meter, and the average value of multiple measurement results is calculated to obtain the average blasting velocity of the explosives; the average blasting vibration is obtained by using a blasting vibration measuring instrument to perform real-time monitoring and data recording during each blasting construction and calculating the average value of the blasting vibrations of multiple blastings; in this embodiment, the historical blasting cycle refers to the time interval from the start of the first blasting construction of each blasting device to the start of the current blasting operation, and this cycle may vary according to the specific blasting project and construction plan.

[0072] In this embodiment, there are complex mutual influence relationships among the maximum blasting delay duration, the average mass of the blasting explosives, the average energy density of the blasting explosives, the average blasting action radius, the average blasting velocity of the explosives, and the average blasting vibration of each blasting device within the historical blasting cycle. The greater the mass of the explosives, the larger the blasting action radius. For explosives with a higher energy density, more energy can be released under the same mass, which may thus result in a higher blasting velocity. A reasonable blasting delay duration can optimize the blasting effect, such as improving the fragmentation degree of the blasted pile and increasing the throwing distance, etc., but too short or too long a delay time may affect the blasting effect. The greater the mass of the explosives, the stronger the blasting vibration generated may be.

[0073] Multiply the average mass of the blasting explosives of each blasting device within the historical blasting cycle by the average energy density of the blasting explosives to obtain the average blasting energy of each blasting device within the historical blasting cycle.

[0074] In this embodiment, the reference precise performance data of the blasting device corresponding to the pre-blasting construction area obtained by matching the blasting construction environment impact index with the reference precise performance data of the blasting device corresponding to each interval of the blasting construction environment impact index preset in the blasting database. The specific matching process is as follows:

[0075] Input the blasting construction environment impact index into the blasting database. The blasting database compares the input blasting construction environment impact index with each preset blasting construction environment impact index range in the blasting database to find the range that matches the blasting construction environment impact index, thereby obtaining the reference precise performance data of the blasting device corresponding to the pre-blasting construction area.

[0076] The reference precise performance data of the blasting device corresponding to the pre-blasting construction area specifically includes the reference blasting energy, the reference blasting action radius, the reference blasting speed of the explosive, and the reference blasting vibration.

[0077] In a specific embodiment, the blasting construction environment impact index is 0.1, and the blasting construction environment impact index range stored in the blasting database is (0, 0.3]. Then, the reference blasting energy corresponding to the blasting construction environment impact index range (0, 0.3] is 2000 joules, the reference blasting action radius is 25 meters, the reference blasting speed of the explosive is 4000 meters per second, and the reference blasting vibration is 0.8 millimeters per second.

[0078] Specifically, the specific analysis process of the blasting precise performance indicators of each blasting device is as follows:

[0079] Perform difference processing on the average blasting energy and the average blasting action radius of each blasting device during the historical blasting cycle respectively with the reference blasting energy and the reference blasting action radius to obtain the blasting energy deviation value and the blasting action radius deviation value of each blasting device.

[0080] Perform ratio processing on the reference blasting speed of the explosive and the reference blasting vibration of each blasting device during the historical blasting cycle respectively with the reference blasting speed of the explosive and the reference blasting vibration to obtain the explosive blasting speed ratio and the blasting vibration ratio of each blasting device.

[0081] Perform comprehensive analysis on the explosive blasting speed ratio, the blasting vibration ratio, the blasting energy deviation value, the blasting action radius deviation value of each blasting device, and the maximum blasting delay duration of each blasting device during the historical blasting cycle to obtain the blasting precise performance indicators of each blasting device. The blasting precise performance indicators of each blasting device are used to comprehensively quantify the precise performance of each blasting device in the blasting operation. The specific analysis method is as follows:

[0082]

[0083] In the formula, Pkk is the blasting precise performance indicator of the kth blasting device, k is the number of each blasting device, k = 1, 2, 3,..., m, and m is the total number of each blasting device, zt k is the explosive blasting speed ratio of the kth blasting device, α1 is the performance impact factor corresponding to the unit value of the explosive blasting speed ratio preset in the blasting database, zd kis the blasting vibration ratio of the k-th blasting device, α2 is the performance impact factor corresponding to the unit value of the blasting energy deviation value preset in the blasting database, pn k is the blasting energy deviation value of the k-th blasting device, Δpn is the allowable blasting energy deviation value preset in the blasting database, α3 is the performance impact factor corresponding to the unit value of the blasting energy deviation value preset in the blasting database, br k is the deviation value of the blasting action radius of the k-th blasting device, α4 is the performance impact factor corresponding to the unit value of the blasting action radius deviation value preset in the blasting database, bt k is the maximum blasting delay duration of the k-th blasting device in the historical blasting cycle, Δbt is the allowable blasting delay duration preset in the blasting database, α5 is the performance impact factor corresponding to the unit value of the maximum blasting delay duration preset in the blasting database.

[0084] It should be explained that the above-mentioned explosive blasting speed ratio refers to the ratio between the reference blasting speed of the explosive and the reference blasting speed of the explosive; the blasting vibration ratio refers to the ratio between the reference blasting vibration component and the reference blasting vibration; the blasting energy deviation value refers to the difference between the average blasting energy and the reference blasting energy; the allowable blasting energy deviation value refers to the maximum allowable difference range between the actual blasting energy and the reference blasting energy in the blasting database; the deviation value of the blasting action radius refers to the difference between the average blasting action radius and the reference blasting action radius; the maximum blasting delay duration refers to the maximum explosion time delay between each blasting device during blasting operations; the allowable blasting delay duration refers to the allowable explosion time delay between each blasting device in order to meet specific blasting effects and safety requirements during blasting operations.

[0085] In this embodiment, the performance influence factor corresponding to the unit value of the explosive blasting speed ratio preset in the blasting database represents the degree of influence of the unit value of the explosive blasting speed ratio on the blasting precision performance index of the blasting device. The blasting database stores the corresponding relationship between the unit value of the explosive blasting speed ratio and its corresponding performance influence factor. For example, when the unit value of the explosive blasting speed ratio is input into the blasting database, the blasting database can match the performance influence factor corresponding to the unit value of the explosive blasting speed ratio; the performance influence factor corresponding to the unit value of the blasting energy deviation value preset in the blasting database represents the degree of influence of the unit value of the blasting energy deviation value on the blasting precision performance index of the blasting device. The blasting database stores the corresponding relationship between the unit value of the blasting energy deviation value and its corresponding performance influence factor. For example, when the unit value of the blasting energy deviation value is input into the blasting database, the blasting database can match the performance influence factor corresponding to the unit value of the blasting energy deviation value; the performance influence factor corresponding to the unit value of the blasting energy deviation value preset in the blasting database represents the degree of influence of the unit value of the blasting energy deviation value on the blasting precision performance index of the blasting device. The blasting database stores the corresponding relationship between the unit value of the blasting energy deviation value and its corresponding performance influence factor. For example, when the unit value of the blasting energy deviation value is input into the blasting database, the blasting database can match the performance influence factor corresponding to the unit value of the blasting energy deviation value; the performance influence factor corresponding to the unit value of the blasting action radius deviation value preset in the blasting database represents the degree of influence of the unit value of the blasting action radius deviation value on the blasting precision performance index of the blasting device. The blasting database stores the corresponding relationship between the unit value of the blasting action radius deviation value and its corresponding performance influence factor. For example, when the unit value of the blasting action radius deviation value is input into the blasting database, the blasting database can match the performance influence factor corresponding to the unit value of the blasting action radius deviation value; the performance influence factor corresponding to the unit value of the maximum blasting delay duration preset in the blasting database represents the degree of influence of the unit value of the maximum blasting delay duration on the blasting precision performance index of the blasting device. The blasting database stores the corresponding relationship between the unit value of the maximum blasting delay duration and its corresponding performance influence factor. For example, when the unit value of the maximum blasting delay duration is input into the blasting database, the blasting database can match the performance influence factor corresponding to the unit value of the maximum blasting delay duration.

[0086] In this embodiment, a relatively large explosive blasting speed ratio may mean inconsistent reaction speeds during the blasting process, resulting in unpredictable and uncontrollable blasting effects. This inconsistency reduces the accuracy of blasting, causing the blasting results to deviate from the expected target. A relatively large blasting vibration ratio indicates more intense vibrations generated by the blasting, which may lead to damage or instability of the surrounding environment. A relatively large blasting energy deviation value, even greater than the preset allowable blasting energy deviation value, may cause unstable blasting effects and even fail to achieve the expected blasting effects. For the blasting accuracy performance index, this will lead to a decline in the index, making the blasting results unpredictable and uncontrollable. A relatively large blasting action radius deviation value may cause the blasting effects to exceed or fall short of the expected range, thus affecting the accuracy of blasting. A relatively long maximum blasting delay duration, even longer than the preset allowable blasting delay duration, results in inaccurate time control during the blasting process. This inaccurate time control may cause the blasting effects to deviate from the expectations and may even pose safety problems. For the blasting accuracy performance index, this will lead to a decline in the index, making the blasting results difficult to accurately predict and control. Therefore, through a detailed analysis of the parameters in the blasting accuracy performance index of the blasting device, the performance characteristics of the blasting device can be more accurately understood, thereby optimizing the blasting plan and improving the accuracy and safety of blasting.

[0087] Furthermore, the determination of the comparison result of the device accuracy performance determines whether each blasting device can carry out blasting construction. The specific determination process is as follows:

[0088] If the blasting accuracy performance index of a certain blasting device is greater than or equal to the threshold value of the blasting device blasting accuracy performance index preset in the blasting database, the comparison result of the device accuracy performance is recorded as the first accuracy performance comparison result.

[0089] It should be noted that when the blasting accuracy performance index of a certain blasting device is greater than or equal to the threshold value of the blasting device blasting accuracy performance index preset in the blasting database, it means that the accuracy performance of this blasting device has reached or exceeded the preset standard or expected value. In other words, this device can exhibit high accuracy and reliability during blasting operations, can complete the blasting task as expected, and may also have better capabilities to control the blasting effects, reduce errors, and ensure safety. Therefore, in this case, this device is considered to meet or exceed the requirements of accuracy performance and can carry out blasting construction.

[0090] If the blasting accuracy performance index of a certain blasting device is less than the threshold value of the blasting device blasting accuracy performance index preset in the blasting database, the comparison result of the device accuracy performance is recorded as the second accuracy performance comparison result.

[0091] It should be noted that when the blasting precision performance index of a certain blasting device is less than the threshold of the blasting precision performance index preset in the blasting database, it means that the precision performance of the blasting device fails to meet the preset standard or expected value. In this case, the device may not exhibit the expected precision and reliability during blasting operations, which may lead to poor blasting effects, large errors, or increased safety risks. Therefore, the device is regarded as not meeting the requirements of precision performance and requires further inspection, debugging, or improvement.

[0092] If the comparison result of the device precision performance is the first precision performance comparison result, the blasting device can carry out blasting construction, and several blasting devices capable of carrying out blasting construction are recorded as each precision blasting equipment.

[0093] In this embodiment, when the comparison result of the device precision performance is the first precision performance comparison result, it means that the precision performance of the blasting device has reached or exceeded the preset standard. Therefore, blasting construction can be carried out. In this case, the device is regarded as one of the precision blasting equipment and can be used in actual blasting operations; when the comparison result of the device precision performance is the second precision performance comparison result, in this case, the device needs to be further inspected, debugged, or improved to improve its precision performance and meet the requirements. At the same time, it may be necessary to consider replacing other blasting devices that meet the requirements to ensure the safety and effect of blasting operations.

[0094] Specifically, the specific analysis process of the blasting construction precision control index is as follows:

[0095] The dynamic data of the blasting construction test during the blasting test process specifically includes the total amount of explosives used during the blasting test cycle of the blasting construction, the real-time blasting vibration acceleration, the real-time blasting vibration rate, and the real-time blasting vibration frequency.

[0096] It should be noted that the above total amount of explosives used is obtained through recording and statistics during the blasting test process. The real-time blasting vibration acceleration is monitored using a professional blasting vibration meter. The real-time blasting vibration rate and the real-time blasting vibration frequency are also monitored using a blasting vibration meter. The vibration meter can not only monitor the vibration acceleration, but also monitor the vibration rate, and can also monitor and analyze the vibration frequency.

[0097] Obtain the precision performance data of each precision blasting equipment during the blasting test process and analyze to obtain the precision performance index of each precision blasting equipment.

[0098] In this embodiment, several blasting devices whose blasting precision performance index is greater than or equal to the threshold value of the blasting precision performance index preset in the blasting database are recorded as each precision blasting device. Therefore, the precision blasting device is a part of the blasting device, and the precision performance data of each precision blasting device is the same as the precision performance data of the above-mentioned blasting devices. Through the analysis process and method of the blasting precision performance index of each blasting device, the precision performance index of each precision blasting device can be analyzed and obtained.

[0099] Comprehensively analyze the total amount of explosive used, real-time blasting vibration acceleration, real-time blasting vibration rate, real-time blasting vibration frequency, and the precision performance index of each precision blasting device during the blasting construction within the blasting test cycle to obtain the precision control index for blasting construction. The precision control index for blasting construction is used to comprehensively quantify the precision control level during the blasting test construction process.

[0100] In this embodiment, during the blasting construction test process, there is indeed an interaction relationship among parameters such as the total amount of explosive used, real-time blasting vibration acceleration, real-time blasting vibration rate, real-time blasting vibration frequency, and the precision performance index of each precision blasting device. The amount of explosive used will directly affect the vibration intensity generated by blasting. Generally speaking, the greater the amount of explosive used, the higher the possible blasting vibration acceleration, vibration rate, and vibration frequency. The total amount of explosive used will also affect the performance of the precision blasting device. For example, if the amount of explosive used is too large, it may cause too much load on the device, thus affecting its precision and reliability. On the contrary, if the amount of explosive used is too small, the expected blasting effect may not be achieved. Vibration acceleration is the rate of change of vibration velocity, while vibration rate is the magnitude of vibration velocity. Therefore, vibration acceleration and vibration rate are closely related during blasting. Generally speaking, the greater the vibration acceleration, the higher the possible vibration rate. During blasting, the level of vibration frequency may affect the distribution and change of vibration acceleration and vibration rate. For example, high-frequency vibration may result in a faster vibration rate and a greater vibration acceleration. The performance index of the precision blasting device will directly affect the vibration control effect during blasting. A device with better performance may be able to more precisely control the intensity, distribution, and propagation range of vibration, thereby reducing the impact on the surrounding environment. The precision performance index of the device is also related to the amount of explosive used. On the one hand, a device with better performance may be able to more effectively utilize the explosive energy to achieve a better blasting effect.

[0101] The specific analysis method of the precision control index for blasting construction is as follows:

[0102]

[0103] Wherein, kz is the precise control index of blasting construction, zy is the total amount of explosives, u1 is the control influence factor corresponding to the unit value of the total amount of explosives preset in the blasting database, e is the natural constant, t0 is the start time of the blasting test period, t1 is the end time of the blasting test period, t is any time point within the blasting test period, t ∈ [t0, t1], zd(t) is the real-time blasting vibration acceleration of the blasting construction at time point t within the blasting test period, Δzd is the reference blasting vibration acceleration preset in the blasting database, zs(t) is the real-time blasting vibration rate of the blasting construction at time point t within the blasting test period, Δzs is the reference blasting vibration rate preset in the blasting database, bp(t) is the real-time blasting vibration frequency of the blasting construction at time point t within the blasting test period, Δbp is the reference blasting vibration frequency preset in the blasting database, n is the number of each precision blasting device, n = 1, 2, 3,...b, b is the total number of precision blasting devices, p1 n is the precision performance index of the nth precision blasting device, and u2 is the weight factor corresponding to the precision performance index of the precision blasting device preset in the blasting database.

[0104] It should be explained that the total amount of explosives mentioned above refers to the total amount of explosives used to complete a specific blasting task during the blasting test period; any time point within the blasting test period refers to any moment between the start and end of the blasting test; the real-time blasting vibration acceleration refers to the acceleration value that changes with time of the ground or other structures under the action of the shock wave generated by the explosion of explosives during the blasting process; the blasting vibration reference acceleration refers to a threshold value used to evaluate the intensity of blasting vibration; the real-time blasting vibration rate refers to the vibration speed value that changes with time of the ground or other structures during the blasting process; the blasting vibration reference rate refers to a threshold value used to evaluate the blasting vibration speed; the real-time blasting vibration frequency refers to the frequency value that changes with time of the vibration wave during the blasting process; the blasting vibration reference frequency refers to a threshold value used to evaluate the range of blasting vibration frequency; the precision performance index of the precision blasting equipment refers to a quantitative index used to evaluate the quality of the blasting equipment performance; the control influence factor corresponding to the preset unit value of the total amount of explosives in the blasting database indicates the degree of control influence of the unit value of the total amount of explosives on the precision control index of blasting construction. The blasting database stores the corresponding relationship between the unit value of the total amount of explosives and its corresponding performance control influence factor. For example, when the unit value of the total amount of explosives is input into the blasting database, the blasting database can match the control influence factor corresponding to the unit value of the total amount of explosives; the weight factor corresponding to the preset precision performance index of the precision blasting equipment in the blasting database indicates the proportion of the precision performance index of the precision blasting equipment in the precision control index of blasting construction. The blasting database stores the corresponding relationship between the precision performance index of the precision blasting equipment and its corresponding weight factor. For example, when the precision performance index of the precision blasting equipment is input into the blasting database, the blasting database can match the weight factor corresponding to the preset precision performance index of the precision blasting equipment in the blasting database.

[0105] In this embodiment, for the total amount of explosive used, more or less explosive may lead to an overly strong blasting effect beyond the expected range, causing unnecessary damage or safety hazards, thus reducing the precision control index of blasting construction. Insufficient explosive may fail to achieve the expected blasting effect, resulting in incomplete blasting or the need for multiple blasts, which will also affect the precision and efficiency of blasting construction. When the real-time blasting vibration acceleration is greater than or less than the preset reference blasting vibration acceleration, too high vibration acceleration may mean that the impact force generated by blasting is too large, having a greater impact on the surrounding environment. Too low vibration acceleration may indicate that the blasting effect is poor and fails to achieve the expected blasting effect. Therefore, whether the real-time blasting vibration acceleration is greater than or less than the preset reference blasting vibration acceleration will affect the precision control index. When the real-time blasting vibration rate is greater than or less than the preset reference blasting vibration rate, too high vibration rate may make it difficult to control the blasting process, increasing uncertainty and risk. Too low vibration rate may mean that the blasting reaction is not fast or thorough enough. When the real-time blasting vibration frequency is greater than or less than the preset reference blasting vibration frequency, too high vibration frequency may lead to uneven energy distribution during the blasting process, increasing the uncertainty and damage range of blasting. Too low vibration frequency may indicate that the energy release during the blasting process is not sufficient or uniform, affecting the blasting effect and precision. For a lower precision performance index of the precision blasting equipment, a lower precision performance index means that the performance of the blasting equipment is not stable or precise enough, which may make it difficult to accurately control various parameters during the blasting process, thus affecting the precision and efficiency of blasting construction and reducing the precision control index. Therefore, through a detailed analysis of each parameter in the precision control index of blasting construction, various factors during the blasting construction process can be more accurately understood as to how they affect the precision control index. This helps to optimize the blasting construction plan, improve the precision and efficiency of blasting, and reduce unnecessary damage and safety hazards.

[0106] Specifically, it is determined whether precision control of blasting construction is required according to the precision comparison result of blasting construction. The specific determination process is as follows:

[0107] If the precision control index of blasting construction is equal to the defined value of the precision control index of blasting construction preset in the blasting database, the precision comparison result of blasting construction is recorded as the first precision comparison result of blasting construction.

[0108] It should be noted that when the blasting construction precision control index is equal to the defined value of the blasting construction precision control index preset in the blasting database, it means that the parameters of the blasting construction (such as explosive dosage, blasting vibration acceleration, vibration rate, etc.) exactly meet the expected standards and are within the safe and controllable range. This indicates that the current blasting construction process has achieved the ideal precision control requirements. This situation usually means that the blasting construction is carried out under an ideal state, neither overly affecting the surrounding environment nor falling short of the expected effect. Therefore, no additional adjustment or precision control is required.

[0109] If the blasting construction precision control index is greater than the defined value of the blasting construction precision control index preset in the blasting database, the blasting construction precision comparison result will be recorded as the second blasting construction precision comparison result.

[0110] It should be noted that when the blasting construction precision control index is greater than the defined value of the blasting construction precision control index preset in the blasting database, it means that the blasting vibrations and vibration effects generated during the current blasting construction process exceed the expected control range, which may cause greater impacts or damages to the surrounding environment, buildings, or personnel. At this time, the blasting parameters may exceed the design standards, resulting in higher factors such as vibration and vibration acceleration, causing potential dangers. To avoid damage or unsafe situations, it is necessary to adjust the blasting construction to ensure that the blasting process is within the safe range.

[0111] If the blasting construction precision control index is less than the defined value of the blasting construction precision control index preset in the blasting database, the blasting construction precision comparison result will be recorded as the third blasting construction precision comparison result.

[0112] It should be noted that when the blasting construction precision control index is less than the defined value of the blasting construction precision control index preset in the blasting database, it means that the blasting construction process may not achieve the expected effect, and there may be situations of insufficient blasting or other low parameters. Although it will not cause excessive vibration or other dangers, it may lead to an unsatisfactory blasting effect and fail to achieve the expected engineering goals. This situation may indicate that the blasting effect is not ideal, and it may be necessary to re-evaluate the explosive dosage, blasting precision, etc. to ensure that the engineering expected goals can be achieved.

[0113] If the blasting construction precision comparison result is the second blasting construction precision comparison result or the blasting construction precision comparison result is the third blasting construction precision comparison result, precision control of the blasting construction is required.

[0114] In this embodiment, when the blasting construction precision comparison result is the second blasting construction precision comparison result, it indicates that factors such as vibration during blasting construction have exceeded the expected control range, and there is a risk of excessive vibration. Therefore, precise control of blasting construction is required to reduce its impact on the surrounding environment. Specific control measures can be to reduce the amount of explosive used in each blast to avoid excessive blasting impact; when the blasting construction precision comparison result is the third blasting construction precision comparison result, it indicates that the current blasting effect has not reached the expectation, and there may be insufficient blasting or unclear effects. Precise control of blasting construction is needed. Specific control measures can be to appropriately increase the amount of explosive under the premise of ensuring safety to ensure that the blasting effect can meet the expected engineering requirements.

[0117] The blasting construction area evaluation module is used to obtain the environmental data of the pre-blasting construction area, analyze and obtain the blasting construction environmental impact index, compare it with the threshold of the blasting construction environmental impact index preset in the blasting database, obtain the environmental impact comparison result, and determine whether blasting construction can be carried out in the pre-blasting construction area according to the environmental impact comparison result.

[0118] The blasting device detection module is used to, if the blasting construction environmental impact index is less than the threshold of the blasting construction environmental impact index preset in the blasting database, record the pre-blasting construction area as a blastable area, match the blasting construction environmental impact index with the reference precise performance data of the blasting device corresponding to each blasting construction environmental impact index interval preset in the blasting database, obtain the reference precise performance data of the blasting device corresponding to the pre-blasting construction area, obtain the precise performance data of each blasting device, and conduct comprehensive analysis with the reference precise performance data of the blasting device to obtain the blasting precise performance index of each blasting device, compare it with the threshold of the blasting device blasting precise performance index preset in the blasting database, obtain the device precise performance comparison result, and determine whether each blasting device can carry out blasting construction according to the device precise performance comparison result.

[0120] The blasting database is used to store the preset threshold of the blasting construction environmental impact index, the preset threshold of the blasting construction environmental impact index, the reference precise performance data of the blasting device corresponding to each interval of the blasting construction environmental impact index, the preset threshold of the precise performance index of the blasting device, the defined value of the precise control index of the blasting construction, the allowable compressive strength of the rock formation, the allowable density of the rock formation, the allowable compressive strength of the soil, the allowable density of the soil, the reference depth of the groundwater level, the reference environmental temperature, the influence factor corresponding to the unit value of the rock formation compressive strength ratio, the influence factor corresponding to the unit value of the rock formation density ratio, the influence factor corresponding to the unit value of the soil compressive strength ratio, the influence factor corresponding to the unit value of the soil density ratio, the influence factor corresponding to the unit value of the groundwater level depth ratio, the influence factor corresponding to the unit value of the real-time environmental temperature difference, the performance influence factor corresponding to the unit value of the explosive blasting speed ratio, the performance influence factor corresponding to the unit value of the blasting energy deviation value, the allowable deviation value of the blasting energy, the performance influence factor corresponding to the unit value of the blasting energy deviation value, the performance influence factor corresponding to the unit value of the blasting action radius deviation value, the allowable blasting delay duration, the performance influence factor corresponding to the unit value of the maximum blasting delay duration, the control influence factor corresponding to the unit value of the total explosive consumption, the reference acceleration of the blasting vibration, the reference rate of the blasting vibration, the reference frequency of the blasting vibration, and the weight factor corresponding to the precise performance index of the precise blasting equipment, etc.
