Description

Technical Field

[0001] This invention relates to the field of safety monitoring of surrounding rock in mine roadways, and in particular to a system and method for monitoring the stability of surrounding rock in roadways. Background Technology

[0002] With the advancement of science and technology, underground geotechnical engineering, such as coal mining and tunnel excavation, has seen significant development. Coal mining has shifted from shallow to deep layers; however, due to the high ground stress at depth, the deformation of the surrounding rock in tunnels is far more complex than in shallow coal seams. Since tunnels play a crucial role in coal mining and material transportation, monitoring the deformation of the surrounding rock is of paramount importance. Methods for measuring stress and deformation in tunnels and other geotechnical engineering have also developed, with a proliferation of experimental equipment and greatly improved experimental conditions, making various field and laboratory experiments more convenient. However, monitoring of the deformation of the surrounding rock in coal mines under the influence of mining disturbances or tunnel excavation disturbances is extremely rare, due to limitations in experimental equipment and the lack of effective measurement methods. Conducting research on the monitoring of surrounding rock deformation can effectively reflect the stress state of the coal seam and the deformation of the surrounding rock during coal mining, providing crucial technical support for exploring the true changing patterns of the surrounding rock in underground engineering. Therefore, research on monitoring systems and methods for deformation of surrounding rock in mine roadways has a significant effect on guiding safe production in underground engineering.

In the tensile strength algorithm of multiple intervals, the source of water accumulation location that interacts with the corresponding water flow locations is determined as the source of water flow magnitude.

[0029] The rock mass strength testing unit is used to take the midpoint of the line connecting the sources of water flow magnitude as the tensile strength at different time periods, and fit the tensile strength of the safe passage rock mass strength based on all the different time periods.

[0057] Beneficial effects: By matching the roadway surrounding rock stress data with the stability parameter range obtained from the tensile strength stability parameter range of the mine's safety passage, the stress data of the roadway surrounding rock in the geological record file is matched, and a simulation map of the tensile strength of the reference safety passage is constructed. Dynamic safety parameters are generated by combining the monitoring and adjustment instructions transmitted by the edge computing gateway. The roadway surrounding rock is preliminarily monitored based on the pre-generated dynamic safety parameters, which reduces the monitoring error in the roadway surrounding rock detection process and improves the problem of low monitoring efficiency caused by low resolution. Furthermore, the simulation map of the tensile strength of the reference safety passage is optimized and adjusted based on the real-time stress data obtained during the detection process. In addition, the monitoring accuracy is continuously improved through the iterative process of the detection process, thereby improving the safety of the mine. Attached Figure Description

[0058] Figure 1 This is a component diagram of a roadway surrounding rock stability monitoring system according to the present invention;

[0059] Figure 2 This is a flowchart illustrating the operation of a roadway surrounding rock stability monitoring method according to the present invention. Detailed Implementation

[0060] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0061] like Figure 1 As shown, the present invention provides a roadway surrounding rock stability monitoring system, comprising:

[0062] The stability parameter range setting component is used to set the stability parameter range for the tensile strength of the mine's safety passage, and to obtain the stress data of the surrounding rock of the roadway within the stability parameter range setting. The stress data of the surrounding rock of the roadway within the stability parameter range setting is the stress data within the tensile strength of the mine's safety passage obtained during the stability parameter range setting process.

[0063] Based on the process of setting the stability parameter range of the mine and the obtained stability parameter range, the roadway surrounding rock stress data is set to provide a reference for subsequent matching and display of existing roadway surrounding rock stress data;

[0064] The tensile strength simulation component is used to set the roadway surrounding rock stress data and the mine safety operation data obtained from the mine database in the monitoring and sensing device platform layer according to the stability parameter range, and match the roadway surrounding rock stress data in the geological record file. That is, the existing roadway surrounding rock stress data in the monitoring groundwater load stored in the monitoring and sensing device platform layer is similar to the mine safety operation data per unit time. Based on the roadway surrounding rock stress data in the geological record file, a reference safety passage tensile strength simulation diagram is constructed, which is a simulation diagram of the safety passage tensile strength at different altitudes constructed based on the existing roadway surrounding rock stress data.

[0065] Based on the stability parameter range obtained by setting the tensile strength stability parameter range of the safety passage in the mine, the stress data of the surrounding rock in the roadway is matched with the stress data of the surrounding rock in the roadway in the geological record file, and a simulation diagram of the tensile strength of the reference safety passage is constructed. This enables the early prediction of the tensile strength shape of the safety passage, and provides an important data foundation for the subsequent generation of dynamic safety parameters that can control the working parameters of the surrounding rock in the roadway throughout the detection process.

[0066] The ground terminal monitoring component is used to receive edge computing gateway adjustment instructions based on the reference safety passage tensile strength simulation diagram and the resolution of the monitoring sensor device. The edge computing gateway adjustment instructions are issued by the edge computing gateway monitoring end. The edge computing gateway monitoring end transmits the edge computing gateway adjustment instructions to the roadway surrounding rock stability monitoring system according to the gateway access function provided by the resolution, generates dynamic safety parameters, and controls the change of the roadway surrounding rock dip angle according to the dynamic safety parameters to obtain real-time stress data within the safety passage tensile strength. That is, the stress data within the safety passage tensile strength obtained by the objective lens on the roadway surrounding rock when the dip angle changes in the safety passage tensile strength.

[0067] Dynamic safety parameters are generated based on the constructed reference safety channel tensile strength simulation diagram and the monitoring and adjustment instructions transmitted by the edge computing gateway. The pre-generated dynamic safety parameters are used to conduct preliminary monitoring of the surrounding rock of the roadway, which reduces the engineer involvement in the roadway surrounding rock detection process, improves the degree of automation, and thus improves the low monitoring efficiency and range caused by low resolution.

[0068] The optimized and adjusted components are used to optimize and adjust the tensile strength simulation diagram of the reference safety passage based on real-time stress data to obtain the latest tensile strength simulation diagram of the reference safety passage, which is the tensile strength simulation diagram of the reference safety passage obtained after optimization and adjustment based on real-time stress data. The dynamic safety parameters are then denoised and adjusted based on the latest tensile strength simulation diagram of the reference safety passage to obtain the latest real-time safety parameters, which are the dynamic safety parameters obtained after denoising and adjustment.

[0069] The dip angle control component is used to control the dip angle of the surrounding rock of the roadway according to the latest real-time safety parameters, and to obtain the stress data of the surrounding rock of the roadway at different unit times. This is the stress data that is finally obtained after the test, which includes the tensile strength of the safety passage required for the test items.

[0070] Based on the real-time stress data obtained during the detection process, the simulation diagram of the tensile strength of the reference safety passage is optimized and adjusted to achieve real-time adjustment and optimization of dynamic safety parameters. Based on the optimized real-time safety parameters, the inclination change of the surrounding rock in the roadway is controlled. This process continuously improves the monitoring accuracy through iteration during the detection process, further ensuring the monitoring accuracy during the detection of the surrounding rock in the roadway.

[0071] The stability parameter range setting component includes:

[0072] The tensile strength data denoising module is used to obtain mine safety operation data from the mine database of the platform layer of the monitoring sensor device, and determine the tensile strength of the safety passage in the mine safety operation data;

[0073] The rock weathering data denoising module is used to set parameter requirements based on the stability parameter range of the tensile strength of the safety passage. That is, it sets safety parameter requirements for different stability parameter ranges of the tensile strength of the safety passage. For example, it can be represented by the stability parameter range setting parameter rock weathering data - stability parameter range setting safety parameter list. The stability parameter range setting parameter rock weathering data is denoised from the mine safety operation data. That is, the data included in the stability parameter range setting parameter requirements of the tensile strength of the safety passage is used to determine the stability parameter range setting safety parameters. This data is denoised from the mine safety operation data. For example, the mine age is the stability parameter range setting parameter rock weathering data.

[0074] The safety parameter determination module is used to generate a stability parameter range setting safety parameter based on the stability parameter range setting parameters of the weathered rock layer and the stability parameter range setting parameters of the tensile strength of the safety passage. Based on the stability parameter range setting parameters of the weathered rock layer, it retrieves the stability parameter range setting parameters of the weathered rock layer and the stability parameter range setting parameters of the tensile strength of the safety passage from the stability parameter range setting parameters list. It then determines a corresponding parameter related to the stability parameter range setting process and further determines the stability parameter range setting safety parameter based on the determined parameter related to the stability parameter range setting process.

[0075] The aforementioned tensile strength data denoising module, rock weathering data denoising module, and safety parameter determination module realize the automatic determination process of the tensile strength of the safety passage. They also realize the determination of the stability parameter range setting parameters and rock weathering data based on the stability parameter range setting requirements of the tensile strength of the safety passage. Furthermore, by combining the two, the stability parameter range setting safety parameters are determined, which generates a set of safety parameters that can be automatically set for the stability parameter range of the mine by monitoring the surrounding rock of the roadway. This automates the stability parameter range setting process and further reduces the degree of engineer involvement in the detection process based on the detection items of the surrounding rock of the roadway.

[0076] The stability parameter range setting monitoring module is used to control the inclination change of the surrounding rock in the roadway within the tensile strength of the safe passage in the mine according to the stability parameter range setting safety parameters, and to obtain the stress data of the surrounding rock in the roadway with the stability parameter range set.

[0077] Based on the above stability parameter range, the safety parameter control of the roadway surrounding rock is set to control the dip angle change stability parameter range, realizing the complete automation and intelligence of the stability parameter range setting process.

[0078] Tensile strength simulation components include:

[0079] The rock weathering data determination module is used to determine the rock weathering data corresponding to the change in tensile strength support rate of the tensile strength of the safety passage. It obtains mine safety operation data from the mine database of the monitoring and sensing device platform layer, and removes noise from the mine safety operation data to extract the rock weathering data corresponding to the change in tensile strength support rate.

[0080] Based on the rock weathering data, the module determines the rock weathering data of tensile strength support rate change;

[0081] The support rate change determination module is used to determine the tensile strength support rate change of the safety passage based on the rock weathering data of the tensile strength support rate change.

[0082] The module determines the change in tensile strength support rate based on the change in support rate.

[0083] The groundwater load magnitude data denoising module is used to denoise the interval variation value corresponding to the change in tensile strength support rate. That is, it is a denoising method to remove the tensile strength characteristic parameter corresponding to the change in tensile strength support rate from the roadway surrounding rock stress data. The stability parameter range is set to denoise the roadway surrounding rock stress data by interval variation value to obtain the groundwater load magnitude data of the change in tensile strength support rate of different channels, which is the specific parameter corresponding to the change in tensile strength support rate of the mine for safe operation.

[0084] The noise reduction module based on the groundwater load magnitude data can remove noise from the roadway surrounding rock stress data within the stability parameter range to extract the groundwater load magnitude data based on the change in tensile strength support rate.

[0085] The groundwater load noise reduction calculation module for different seasons is used to calculate the groundwater load for different seasons based on the groundwater load magnitude data of all tensile strength support rate changes in the existing roadway surrounding rock detection cloud. This is the detected groundwater load that is similar to the groundwater load magnitude data of the same tensile strength support rate change determined per unit time. The detected groundwater load is the groundwater load data of the relevant records obtained when the same tensile strength was detected in other mines and stored in the monitoring sensor device platform.

[0086] The groundwater load data determined by the groundwater load data denoising module is used as the denoising calculation reference. The groundwater load in different seasons is calculated by denoising, which provides basic data for the subsequent construction of the tensile strength simulation diagram of the reference safety passage.

[0087] The reference simulation diagram construction module is used to construct a reference safety passage tensile strength simulation diagram based on the tunnel surrounding rock stress data in the geological record file of groundwater load in different seasons. It reconstructs the horizontal and vertical axes of the interval variation values ​​in the tunnel surrounding rock stress data in the geological record file, and splices and fits the horizontal and vertical axis-modified part of the algorithm according to the acquisition order of the interval variation values ​​to obtain the reference safety passage tensile strength simulation diagram.

[0088] Based on the horizontal and vertical axis transformation of the range variation values ​​of the roadway surrounding rock stress data in the geological record file, a simulation diagram of the tensile strength of the reference safety passage is constructed, realizing the early prediction of the tensile strength shape of the safety passage, and providing an important data foundation for the subsequent generation of dynamic safety parameters that can control the working parameters of the roadway surrounding rock throughout the detection process;

[0089] In this embodiment, the change in tensile strength support rate is a tensile strength appearance feature used to distinguish the tensile strength of different safety passages. This change in tensile strength support rate can be denoised from the stress data obtained from the surrounding rock of the roadway.

[0090] Ground terminal monitoring components include:

[0091] The seepage zone construction module is used to determine the pressure per unit area of ​​the change in dip angle of the roadway surrounding rock at different time periods based on the simulation diagram of the tensile strength of the reference safety passage. That is, to initially determine the pressure per unit area of ​​the change in dip angle of the roadway surrounding rock in the tensile strength of the safety passage during the test. Based on the pressure per unit area of ​​the change in dip angle of the roadway surrounding rock at different time periods and the simulation diagram of the tensile strength of the reference safety passage, the seepage zone of the change in dip angle of the roadway surrounding rock is generated.

[0092] The pressure per unit area of ​​the roadway surrounding rock dip angle change at different time periods is determined by the simulation diagram of the tensile strength of the reference safety passage and combined with the simulation diagram of the tensile strength of the reference safety passage to obtain the seepage interval of the roadway surrounding rock dip angle change process, thus realizing the algorithmic calculation of the pressure per unit area of ​​the roadway surrounding rock dip angle change at different time periods.

[0093] The edge computing gateway wireless signal transmission module is used to transmit the seepage range of the roadway surrounding rock dip angle change process to the edge computing gateway monitoring end according to the resolution of the monitoring sensor device, and receive the corresponding wireless signal instructions. That is, the wireless signal content of the received roadway surrounding rock dip angle change process seepage range of the edge computing gateway monitoring end, including the edge computing gateway adjustment instructions for the pressure per unit area of ​​roadway surrounding rock dip angle change at different time periods.

[0094] The algorithmic results of the automatically generated representation of the pressure per unit area of ​​the roadway surrounding rock change based on the change in dip angle at different time periods are sent to the edge computing gateway monitoring end and receive wireless signal instructions from engineers. This enables engineers to participate in decision-making regarding the pressure per unit area of ​​the roadway surrounding rock change in dip angle, thereby making the decision on dynamic safety parameters of the roadway surrounding rock more flexible. Furthermore, the participation of engineers in decision-making further ensures the reliability of the determined dynamic safety parameters.

[0095] The safety parameter generation module is used to adjust the pressure per unit area of ​​the roadway surrounding rock dip angle change based on the edge computing gateway adjustment instructions in the wireless signal commands. This means that after receiving the seepage interval during the change of the roadway surrounding rock dip angle, the edge computing gateway monitoring terminal issues instructions to adjust the pressure per unit area of ​​the roadway surrounding rock dip angle change at different time periods. For example, the modified pressure per unit area of ​​the roadway surrounding rock dip angle change calibrated by the edge computing gateway monitoring terminal on the edge computing gateway input display screen is directly used as the adjusted pressure per unit area of ​​the roadway surrounding rock dip angle change. This results in the adjusted pressure per unit area of ​​the roadway surrounding rock dip angle change, which is the pressure per unit area of ​​the roadway surrounding rock dip angle change adjusted according to the edge computing gateway adjustment instructions. Dynamic safety parameters are then generated based on this adjusted pressure per unit area of ​​the roadway surrounding rock dip angle change. These parameters control the change of the roadway surrounding rock dip angle according to the pressure per unit area of ​​the adjusted roadway surrounding rock dip angle change. These parameters may include control parameters such as the maximum dip angle, the direction of dip angle change, and the dip angle change distance.

[0096] The pressure per unit area of ​​the roadway surrounding rock dip angle change is adjusted and corrected according to the edge computing gateway adjustment instructions in the wireless signal instructions. Furthermore, dynamic safety parameters are generated based on the corrected pressure per unit area of ​​the roadway surrounding rock dip angle change. The decision-making process of dynamic safety parameters adds the engineer decision-making link, which further ensures the reliability of the determined dynamic safety parameters.

[0097] The real-time dip angle change acquisition module is used to control the dip angle change of the surrounding rock of the roadway according to the real-time safety parameters in the dynamic safety parameters and to acquire the real-time stress data within the tensile strength of the safety passage.

[0098] The module acquires real-time dip angle changes to control the initial dip angle changes of the surrounding rock in the roadway during the detection process.

[0099] The seepage zone construction module includes:

[0100] The water flow position detection unit is used to determine the horizontal and vertical axis data representation of the tensile strength of the safety passage at different altitudes based on the simulation diagram of the tensile strength of the safety passage, and to determine the water flow position at each water accumulation position at different altitudes of the safety passage with different tensile strengths.

[0101] The water flow magnitude detection unit is used to divide the tensile strength simulation map of the reference safety passage into multiple interval tensile strength simulation maps with different groundwater load interference. In the tensile strength algorithm of multiple intervals, the water accumulation location source of all corresponding water flow locations interacting with each other is determined. That is, the water accumulation location source includes the water accumulation location belonging to multiple interval tensile strength algorithms. The water flow locations at different elevations of the safety passage at these multiple water accumulation locations interact with each other to determine the source of water flow magnitude.

[0102] The rock mass strength detection unit is used to take the midpoint of the line connecting the sources of water flow magnitude as the tensile strength at different time periods, and to fit the tensile strength of the rock mass of the safe passage according to all the different time periods (that is, to use the simulation map obtained by fitting all the different time periods of tensile strength according to the approximate direction of the change of the dip angle of the surrounding rock of the tunnel as the tensile strength of the rock mass of the safe passage).

[0103] The midpoint of the line connecting multiple water accumulation locations from the source of water flow size is taken as the center point of tensile strength. Furthermore, the tensile strength rock mass strength of the safe passage is fitted based on the center point of tensile strength. This ensures that the pressure per unit area of ​​the subsequently determined change in the dip angle of the surrounding rock in the roadway is located as close as possible to the center of the tensile strength of the safe passage. This guarantees the field of view of the stress data obtained from the surrounding rock in the roadway. Therefore, when the rock mass strength dip angle of the surrounding rock in the roadway changes at the tensile strength of the safe passage, the obstruction of the field of view by the inner wall of the tensile strength during the change in dip angle can be minimized.

[0104] The rock corrosion rate assessment unit is used to generate the seepage zone of the roadway surrounding rock dip angle change process based on the curvature characteristics of the safety passage at different altitudes, namely the curvature data of the water accumulation position on the surface of the safety passage tensile strength, the shear slip failure method corresponding to the safety passage tensile strength, and the rock strength of the safety passage tensile strength.

[0105] Determining the maximum dip angle of the surrounding rock at the corresponding water accumulation point based on the curvature characteristics of the tensile strength of the safety passage at different altitudes can ensure that the instantaneous dip angle change rate of the surrounding rock corresponds to the curvature of the tensile strength of the safety passage at different altitudes. This improves the flexibility of the dip angle change rate of the surrounding rock within the tensile strength of the safety passage and ensures the observability of the stress data obtained during the dip angle change process of the surrounding rock.

[0106] In this embodiment, the shear slip failure method is a pre-trained algorithm that uses a large amount of curvature feature data of the tensile strength of the safety passage at different altitudes and the maximum value of the pressure tilt angle change per unit area within the tensile strength of the safety passage as samples. This algorithm can determine the maximum value of the tilt angle of each water accumulation at the tensile strength of the safety passage rock mass by using the input curvature feature data of the tensile strength of the safety passage at different altitudes.

[0107] The rock mass corrosion rate assessment unit includes:

[0108] The component for determining rock mass strength at different depths is used to determine the tangent of the rock mass strength at different times of the tensile strength of the safety passage. The component takes the rock mass strength at different depths that includes the tensile strength at different times as the tensile strength axis at the corresponding tensile strength at different times, thus determining the plane perpendicular to the extension direction of the tensile strength of the safety passage.

[0109] The component for determining rock mass strength at different depths can determine the rock mass strength at different depths along the tensile strength axis perpendicular to the direction of tensile strength derivation of the safety passage.

[0110] The component for determining the frequency of strata activity at different depths is used to determine all water accumulation locations where the tensile strength of the safety passage at different altitudes and the rock mass strength at different depths intersects with the tensile strength axis. After taking the displacement of the surrounding rock at different times corresponding to the tensile strength, the frequency of strata activity at different depths is determined after taking the displacement of the surrounding rock at different times corresponding to the tensile strength of the safety passage at different altitudes.

[0111] The rock corrosion rate assessment component is used to input the activity frequency of strata at different depths after the displacement of all surrounding rock at different time periods of tensile strength into the shear slip failure method of the corresponding tensile strength of the safety passage. It determines the degree of shear slip failure at different time periods of the corresponding tensile strength, and assesses the rock corrosion rate of the rock mass strength of the safety passage based on the degree of shear slip failure. This results in the extension process of the simulated rock mass strength of the safety passage tensile strength according to the determined degree of shear slip failure at different time periods of all tensile strengths, generating the seepage interval of the roadway surrounding rock dip angle change process.

[0112] Based on a pre-trained shear slip failure method and the frequency of strata activity at different depths after representing the maximum bending degree of all surrounding rock displacements at different times of tensile strength, the degree of shear slip failure at different times of tensile strength is determined. This allows for a reasonable rate of change in the dip angle of the roadway surrounding rock along the tensile strength rock mass of the safety passage, ensuring the observability of stress data obtained during the change of the dip angle of the roadway surrounding rock. In this embodiment, the frequency of strata activity at different depths after representing the maximum bending degree of all surrounding rock displacements at different times of tensile strength is one way to express the curvature characteristics of the tensile strength of the safety passage at different altitudes. Correspondingly, the shear slip failure method in this embodiment is also a pre-trained algorithm that uses a large number of strata activity frequencies at different depths after representing the maximum bending degree of all surrounding rock displacements at different times of tensile strength and the maximum dip angle within the tensile strength of the safety passage at different times of tensile strength as samples. This algorithm can determine the degree of shear slip failure at different times of tensile strength of the safety passage by using the input strata activity frequencies at different depths after representing the maximum bending degree of all surrounding rock displacements at different times of tensile strength.

[0113] Optimize and adjust components, including:

[0114] The rock mass fracture optimization and adjustment module is used to adjust the rock mass fracture safety parameters in the dynamic safety parameters (i.e., the safety parameters used to control the rock mass fracture parameters of the rock mass fracture equipment installed on the surrounding rock of the roadway (such as rock stratum weathering of the rock mass fracture equipment)) based on real-time stress data (i.e., to adjust the rock mass fracture safety parameters in the dynamic safety parameters based on the display effect of the acquired real-time stress data).

[0115] This enables optimized control of the rock mass crack safety parameter in the dynamic safety parameters during the dip angle change of the surrounding rock in the roadway (during the detection process), ensuring the effectiveness of the acquired real-time stress data.

[0116] The dynamic simulation map update module is used to optimize and adjust the reference safety passage tensile strength simulation map based on real-time stress data to obtain the latest reference safety passage tensile strength simulation map (that is, to reconstruct the horizontal and vertical axes based on real-time stress data to obtain a new local safety passage tensile strength simulation map corresponding to the water accumulation point, and to update the newly constructed local safety passage tensile strength simulation map in the reference safety passage tensile strength simulation map).

[0117] To optimize and adjust the simulation diagram of the tensile strength of the reference safe passage during the change of the dip angle of the surrounding rock in the roadway;

[0118] The stress visualization module is used to visualize the macroscopic stress of tensile strength (i.e., the interval variation value of the tensile strength of the safe passage obtained from the predicted water accumulation point to be found in the safe passage after a certain period of time) based on the latest reference safety passage tensile strength simulation diagram and the unit time safety parameters in the dynamic safety parameters (i.e., the safety parameters executed by the surrounding rock of the roadway at a unit time, such as the parameters for monitoring the instantaneous dip angle change rate and real-time dip angle change direction of the surrounding rock of the roadway) and the roadway surrounding rock stress data in the geological record file (the roadway surrounding rock stress data in the geological record file matched with the stability parameter range set according to the stability parameter range set for the tensile strength stability parameters of the mine's safe passage).

[0119] Based on the latest simulation diagram of the tensile strength of the safety passage, the unit time control parameters, and the stress data of the surrounding rock of the tunnel in the geological record file, the macroscopic stress of the tensile strength can be generated in advance, which improves the low resolution of real-time stress data to the edge computing gateway monitoring end and provides the engineers at the edge computing gateway monitoring end with a predictive reference for adjusting the monitoring, thereby improving the monitoring efficiency to a certain extent.

[0120] The adjustment transmission module is used to transmit the tensile strength macroscopic stress to the edge computing gateway monitoring end for display according to the resolution of the monitoring sensor device, and to receive the real-time monitoring adjustment command input by the edge computing gateway monitoring end, which is the command used to adjust and monitor the real-time dip angle change of the roadway surrounding rock in real time.

[0121] Real-time stress data and real-time monitoring and adjustment commands are transmitted between the surrounding rock of the roadway and the monitoring terminal of the edge computing gateway.

[0122] The optimization and adjustment module is used to denoise and adjust the dynamic safety parameters according to the real-time monitoring and adjustment instructions. It denoises the simulation graph obtained by fitting the safety parameters contained in the real-time monitoring and adjustment instructions with the previous dynamic safety parameters, and uses the safety parameters in the denoised simulation graph as the latest safety parameters at the corresponding time to obtain the latest real-time safety parameters, which are the safety parameters of the dynamic safety parameters adjusted according to the real-time monitoring and adjustment instructions at the unit time.

[0123] Based on real-time monitoring and adjustment instructions, the dynamic safety parameters are denoised and adjusted, enabling engineers at the edge computing gateway monitoring end to adjust and monitor the dynamic safety parameters in real time. This function is not a necessary step to finally complete the roadway surrounding rock detection project, but it can give engineers more monitoring options.

[0124] Tilt angle change control components include:

[0125] The rock mass volume confirmation module is used to control the dip angle change of the surrounding rock in the tunnel based on the latest real-time safety parameters until the latest obtained stress data meets the rock mass volume monitoring trigger condition. (When the latest obtained stress data indicates that the surrounding rock in the tunnel has reached the endpoint of the pressure per unit area of ​​the reference tunnel surrounding rock dip angle change, it is determined that the latest obtained stress data meets the rock mass volume monitoring trigger condition. For example, the engineer's monitoring judgment method can be used to determine whether the latest obtained stress data represents the endpoint of the pressure per unit area of ​​the reference tunnel surrounding rock dip angle change, or a pre-trained endpoint water accumulation recognition algorithm can be used to identify and judge the latest obtained stress data. This endpoint water accumulation recognition algorithm is based on a large number of actual endpoint water accumulation values ​​that have been calibrated to include the pressure per unit area of ​​the reference tunnel surrounding rock dip angle change in the tensile strength of the safety passage.) Once the data (or interval change values) of the influence of the interval change value region corresponding to the water accumulation are trained, the endpoint water accumulation identification algorithm can identify the interval change value region corresponding to the endpoint water accumulation when the stress data of the surrounding rock of the tunnel includes the pressure per unit area of ​​the reference tunnel surrounding rock dip angle change. Then, according to the resolution of the monitoring sensor device, it sends a rock mass volume confirmation instruction to the edge computing gateway monitoring end (used to confirm with the engineer at the edge computing gateway monitoring end whether rock mass volume detection (i.e. whether rock mass volume affects the dip angle change of the surrounding rock of the tunnel) is performed), and receives a confirmation wireless signal instruction from the edge computing gateway monitoring end (i.e., an instruction containing the confirmation wireless signal content of whether the engineer at the edge computing gateway monitoring end agrees to rock mass volume detection (i.e. whether rock mass volume affects the dip angle change of the surrounding rock of the tunnel)).

[0126] The rock mass volume control module is used to control the change of the dip angle of the surrounding rock mass in the roadway according to the confirmation wireless signal instruction. That is, when the confirmation wireless signal instruction means that the engineer agrees to the rock mass volume detection, it controls the change of the dip angle of the surrounding rock mass in the roadway and obtains the stress data of the surrounding rock in the roadway at different unit times.
