Technical Field

[0001] The invention relates to the technical field of seismic wave monitoring, and in particular to an engineering blasting seismic wave monitoring device and a detection method thereof. Background Art

[0002] Seismic wave monitoring for engineering blasting is an important measure to ensure that the impact of blasting activities on the surrounding environment and structures is controllable. The specific operation method includes the following steps: Geological survey: Understand the geological conditions of the blasting area in detail, including rock types, stratigraphic structure and groundwater conditions. Environmental survey: Assess the conditions of the surrounding environment and buildings, and determine the areas and objects that need to be monitored. Select appropriate seismic wave monitoring equipment such as seismometers, accelerometers, particle velocimeters and strain gauges according to monitoring needs. Determine the monitoring objectives and requirements, and formulate a detailed monitoring plan, including the layout of monitoring points, equipment installation methods, data collection frequency and time, etc. According to the monitoring plan, select appropriate monitoring points in and around the blasting area. Monitoring points should cover the blasting center, boundary areas and near key structures.

[0003] Seismic waves generated by blasting may cause damage to surrounding buildings and structures. By monitoring seismic waves, potential safety hazards can be discovered in a timely manner, and appropriate protective measures can be taken to protect the safety of buildings and structures. Seismic wave monitoring can predict the impact of blasting on the surrounding environment in advance, ensure the safety of surrounding personnel during the blasting process, and avoid secondary disasters caused by blasting. By monitoring the amplitude, frequency, and duration of seismic waves, the energy output of the blasting can be quantified and whether the blasting has achieved the expected effect can be evaluated. Analyzing seismic wave data can provide a reference for subsequent blasting design, optimize blasting parameters, and improve blasting efficiency and effectiveness.

[0004] For example, the Chinese authorized patent "An Active Source Microseismic Monitoring Device and Method" with application number CN201810005291.1 includes: monitoring well I, fracturing well, and monitoring well II; the monitoring well I and monitoring well II are respectively arranged on both sides of the fracturing well, and a seismometer is arranged on one side of the monitoring well I, and an electric spark instrument is arranged on one side of the monitoring well II. The present invention adopts the principle of interchange of seismic waves. Before fracturing, electric sparks are used to conduct a simulated substitution test at the fracturing position to measure the velocity of the formation seismic waves, establish the relationship between the source energy and the fracture level, and perform microseismic monitoring during the fracturing construction while keeping the entire monitoring system unchanged, so that it better meets the conditions of seismic interchange; in the process of microseismic inversion, the field-calibrated formation seismic wave velocity and energy conversion relationship table is used to ensure accurate fracture positioning and accurate level judgment, so that the monitoring and evaluation are scientific and reliable.

DETAILED DESCRIPTION

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1-10As shown, the engineering blasting seismic wave monitoring device is a high-precision instrument for monitoring and evaluating seismic waves generated by blasting engineering and their impact on the surrounding environment. Its structure includes a bracket assembly 1, a monitoring box 2, an antenna 3 and a monitoring mechanism 4. The bracket assembly 1 is firmly mounted on the ground of the blasting area to be monitored to ensure that the entire device can remain stable during the blasting process and avoid data errors caused by vibration. The monitoring box 2 is a core component and is fixed on the upper part of the bracket assembly 1. Its design takes into account multiple protection measures such as dustproof, waterproof, and shockproof to ensure that it can still work normally in various harsh environments. The monitoring box 2 integrates multiple high-precision sensors and data processing modules, which can collect and process seismic wave data in real time. An antenna 3 is installed above the monitoring box 2. This is a high-gain antenna 3, which is responsible for wirelessly transmitting the processed data to a remote data center. The design of the antenna 3 ensures the stability and reliability of data transmission, and ensures accurate data transmission even in areas with weak signals. The monitoring mechanism 4 is installed below the monitoring box 2, close to the ground. This design enables the monitoring mechanism 4 to sense ground vibration more directly and sensitively. The monitoring mechanism 4 detects seismic waves in real time through a built-in sensing component 41. The sensing component 41 can capture weak vibration signals generated by blasting.

[0027] The monitoring mechanism 4 detects the seismic waves through the sensing component 41, and transmits the vibration signal to the liquid water in the fixing component 42 through the principle of mechanical conduction. The fluctuations of the liquid water during the vibration will directly affect the pressure sensor 44 and the light sensor 454 installed in the fixing component 42. These sensors can accurately measure the pressure changes of the liquid water and the light changes caused by the change of water flow, and then obtain data such as the intensity, frequency and duration of the seismic waves.

[0028] The data collected by these sensors are first transmitted to the data processing module in the monitoring box 2 for real-time calculation and analysis. The calculation module inside the monitoring box 2 processes and converts various data of the seismic wave through a preset algorithm, and extracts meaningful information, such as magnitude, epicenter location, focal depth, etc. The processed seismic wave data is sent to the remote data center through antenna 3, and the data center conducts further analysis and storage. The experts and automation systems in the data center can evaluate the impact of the blasting on the surrounding environment and buildings based on real-time data, and generate relevant reports. If the data center detects an abnormal situation, such as the intensity of the seismic wave exceeds the safety threshold, the system will immediately send an alarm signal to the construction party through antenna 3. This real-time early warning system can notify the construction party to take emergency measures in the first time to avoid possible safety accidents. The alarm signal sent by antenna 3 can trigger the alarm device on the site, such as warning lights and alarm sounds, to remind the on-site staff to evacuate quickly or take protective measures.

[0029] like Figure 2As shown, the support assembly 1 includes a support rod 11, a mounting base 12, a horizontal holding rod 13 and a stabilizing block 14; the support rod 11 is installed under the monitoring box 2, and the support rod 11 is the main structural member connecting the monitoring box 2 and the mounting base 12. It is installed under the monitoring box 2 and firmly supports the monitoring box 2 through a sturdy fixing device. To ensure that the monitoring box 2 is at the best height and angle, thereby ensuring the accuracy of the monitoring data. To provide sufficient support and stability. The bottom of the base is provided with an anti-slip pad or an anchoring device to ensure the stability of the monitoring box 2. The mounting base 12 is installed under the support rod 11 and is the part of the support assembly 1 that contacts the ground. The stabilizing block 14 is installed under the horizontal holding rod 13 and is a key component to further enhance the stability of the device. The stabilizing block 14 is usually made of high-density material and has a large weight and volume. The design of the stabilizing block 14 ensures that the support assembly 1 can remain stable and will not tilt or move when subjected to external vibration or impact.

[0030] like Figure 2 As shown, the horizontal holding rod 13 is installed at the center point below the monitoring box 2. The horizontal holding rod 13 is a key component to ensure that the monitoring box 2 works in a horizontal state. It is fixed at the center point of the monitoring box 2 to maintain the horizontal position of the monitoring box 2. The horizontal holding rod 13 is usually equipped with a level gauge or an electronic level sensor, which can detect and adjust the horizontal state of the monitoring box 2 in real time to avoid affecting the accuracy of the monitoring data due to tilt. The stabilizing block 14 is installed below the horizontal holding rod 13.

[0031] There are four support rods 11, which are tilted at 45° to evenly disperse the forces from different directions, thereby improving the overall stability. This setting can effectively resist vibrations in the horizontal and vertical directions, so that the monitoring device remains stable during the blasting process. The mounting base 12 below the support rods 11 is set on the same horizontal plane. The flat base provides a stable contact surface to ensure that the device is in close contact with the ground and reduce the tilt of the device caused by uneven ground. The horizontal holding rod 13 is located at the intersection of the diagonals below the monitoring box 2. The holding rod at the center position can more effectively keep the monitoring box 2 horizontal and reduce data errors caused by tilting. The stabilizing block 14 is set in a bowl shape. The bowl-shaped design increases the contact area and enhances the friction, making the device more stable on the ground and not easy to slide. The bowl-shaped shape can effectively prevent the device from tipping over, especially when it is impacted by external forces, further improving the safety and stability of the device.

[0032] like Figure 3As shown, the monitoring mechanism 4 includes a sensing component 41, a fixed component 42, a flow measuring component 43, a pressure sensor 44 and a measuring component 45; the sensing component 41 is installed at the bottom of the fixed component 42, and can instantly capture and record the weak vibration signal generated during the blasting process. The fixed component 42 is installed under the monitoring box 2, directly supporting the sensing component 41 and other devices. It bears the weight of the entire monitoring mechanism 4, and ensures that the sensing component 41 can operate accurately without being affected by the outside world through structural design. The flow measuring component 43 is installed inside the fixed component 42, and the flow measuring component 43 is built into the fixed component 42 to receive and transmit the flow of liquid water. Under the action of vibration, the flow measuring component 43 can accurately record and measure the flow speed and direction of liquid water, thereby providing an important basis for subsequent data analysis. The pressure sensor 44 is installed inside the fixed component 42, and is specifically used to monitor and record the pressure changes in liquid water. These sensors can detect tiny pressure fluctuations in real time and provide key data such as the intensity and frequency of ground vibration caused by blasting. The measuring component 45 is installed on the fixing component 42, and obtains the specific situation of the shear wave in the seismic wave by calculating the incoming and outgoing water flow.

[0033] like Figure 4 As shown, the sensing component 41 includes a rod 411, a piston 412, an overflow port 413, a bellows 414 and a contact block 415; the rod 411 is arranged inside the fixed component 42, and the rod 411 is the main structure of the sensing component 41, and is installed inside the fixed component 42. The piston 412 is installed on the rod 411, and the piston 412 is installed above the rod 411, tightly connected with the rod 411, and can move along the axial direction of the rod 411. The overflow port 413 is opened on the side of the piston 412, and the overflow port 413 is opened on the side of the piston 412, and is used to adjust the flow of liquid water inside the sensing component 41. It ensures that when the pressure changes, the excess liquid water can be released through the overflow port 413 to avoid the instability of the sensing component 41 caused by pressure accumulation. The lower end of the bellows 414 is mounted on the shaft 411, and the contact block 415 is mounted below the shaft 411. The contact block 415 is arranged in a terraced shape. The contact block 415 is mounted below the shaft 411 and is the bottom structure of the sensing component 41. The terraced shape can more effectively contact and transmit the force of ground vibration. The terraced design provides a larger contact area and stability, which helps to accurately sense the vibration signal of the seismic wave.

These sleeves are usually made of high-strength metal or alloy, have good durability and pressure resistance, and can remain stable in a shock and vibration environment. The sliding hole 422 is opened below the vertical sleeve 421, and the sliding hole 422 is used to allow the rod body 411 to slide therein, and the bridge sleeve 423 is installed in the middle of the two vertical sleeves 421, and the bridge sleeve 423 is used to facilitate the movement of water in the two vertical sleeves 421, so as to record the changes in the transverse waves, and the rotation hole 424 is opened in the middle of the bridge sleeve 423, and the rotation hole 424 is used to install the rotation shaft 431.

[0035] like Figure 6 As shown, the flow measuring component 43 includes a rotating shaft 431, an impeller 432, a mounting ring 433 and a spotlight 434.

The impeller 432 is mounted on the side of the rotating shaft 431, and its cross-sectional shape is designed to be semicircular. This design can effectively capture the kinetic energy of the fluid when the liquid water flows through, and convert it into rotational power, so as to measure the speed and direction of the water flow. The mounting ring 433 is installed above the impeller 432 to support and fix the impeller 432. It is usually designed as an annular structure, which can stably fix the impeller 432 to ensure its stable operation and accurate measurement under the action of the fluid. The spotlight 434 is arranged above the mounting ring 433 and is arranged in a circular array. These spotlights 434 generally use infrared technology to ensure the reliability and accuracy of the measurement data.

[0036] like Figure 8 As shown, the measuring component 45 includes a fixing ring 451, a through hole 452, a hollow sleeve 453 and a photosensitive sensor 454; the fixing ring 451 is installed on the top of the mounting component, the through hole 452 is opened in the middle of the fixing ring 451, the hollow sleeve 453 is installed on the through hole 452, the photosensitive sensor 454 is installed on the top of the hollow sleeve 453, and the photosensitive sensor 454 is installed on the top of the hollow sleeve 453 to detect and measure the change of the light signal.

The pressure sensor 44 detects and monitors this part of the pressure change and transmits it to the monitoring box 2. The transverse wave of the seismic wave will cause the same Different vertical sleeves 421 in the group fixing component 42 are subjected to vibrations with a certain time difference, so that a part of the water flow will enter another vertical sleeve 421 through the bridge sleeve 423.
