DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The deep rock burst roadway support damage detection system according to the embodiments of the present invention includes a plurality of detection devices, a data acquisition device 4, and a data analysis device 5. The plurality of detection devices are arranged in the roadway at intervals along the axial direction of the roadway. The detection device includes a roadway surface detection component 1, a concrete detection component 2, and a cable bolt detection component 3. The roadway surface detection component 1 is used to detect the displacement of the roadway surface. The concrete detection component 2 is arranged in the concrete filling layer on the roadway surface to detect the stress inside the concrete filling layer. The cable bolt detection component 3 is arranged on the roadway wall and connected to the tail end of the cable bolt to detect the tension of the cable bolt. The data acquisition device 4 is communicatively connected to the detection device to acquire the data information detected by the detection device. The data analysis device 5 is communicatively connected to the data acquisition device 4 to receive and analyze the data information acquired by the data acquisition device 4.

[0031] When the deep rock burst roadway support damage detection system according to the embodiments of the present invention is in use, the roadway surface detection component 1 detects the displacement of the roadway surface in real time and collects data. The concrete detection component 2 is located in the concrete filling layer on the roadway surface and collects the stress data inside the concrete. The cable bolt detection component 3 is installed on the roadway wall and connected to the tail end of the cable bolt to collect the tension data of the cable bolt. The data collected by the detection device is sent to the data acquisition device 4 through the communication connection. The data acquisition device 4 receives the data information transmitted by the detection device and performs preliminary sorting and storage. The data analysis device 5 receives the data information of the data acquisition device 4, analyzes and processes the data, and evaluates the damage state and potential risks of the roadway support system.

[0032] The deep rock burst roadway support damage detection system according to the embodiments of the present invention can detect the displacement of the roadway surface, the stress of the concrete filling layer, and the tension of the cable bolt in real time, providing real-time data support for the safe operation of the roadway. Through the collaborative work of different detection components, detailed information of the roadway support structure can be accurately obtained, improving the accuracy of detection. The system can detect different roadway conditions, has strong adaptability, and is not limited to specific roadway structures. By analyzing the collected data, potential problems in the roadway support system can be detected early, and measures can be taken in time to prevent accidents. Compared with the traditional monitoring system, the system structure of the present invention is simpler, the layout and maintenance difficulty are reduced, and the cost is lower. The data analysis device 5 can perform intelligent analysis on the collected data, providing scientific and reasonable suggestions for decision-makers and optimizing the management of the roadway support system.

[0033] Optionally, the data acquisition device 4 includes, but is not limited to, any one or several combinations of industrial computer devices and mobile intelligent terminals, and the data analysis device 5 includes, but is not limited to, any one or several combinations of laptops, tablets, and smartphones.

[0034] In some embodiments, the roadway surface detection assembly 1 includes a bearing base 101, a detection head 102, a rangefinder 103, a level 104, a laser emitter 105, a photosensitive sensor 106, and a detection scale 107. The bearing base 101 is used to connect to the roof of the roadway. The detection head 102 is connected to the bearing base 101 and is located below the bearing base 101. The level 104 is provided on at least one of the bearing base 101 and the detection head 102. The rangefinder 103 is provided at the bottom of the detection head 102 to measure the distance between the rangefinder 103 and the roadway floor. The detection scale 107 is provided on both sides of the roadway, and the photosensitive sensor 106 is provided on the detection scale 107. The laser emitter 105 is provided on both sides of the detection head 102 in the width direction of the roadway, and is respectively used to emit laser towards the photosensitive sensors 106 provided on both sides of the roadway.

[0035] As Figure 2 and Figure 3 shown, the bearing base 101 serves as the base of the system, which is responsible for firmly installing the entire detection head 102 on the roof of the roadway. The detection head 102 is connected below the bearing base 101 and is the place where various detection devices are installed. The rangefinder 103 is installed at the bottom of the detection head 102 to measure the vertical distance from the detection head 102 to the roadway floor, so as to obtain the height information of the roadway. The level 104 is installed on the bearing base 101 or the detection head 102 to ensure the levelness of the entire detection assembly during installation and use, so as to ensure the accuracy of the data. The laser emitter 105 is located on both sides of the detection head 102 and is used to emit laser signals to both sides of the roadway to measure the width of the roadway and the conditions of both sides. The photosensitive sensor 106 is installed on the detection scale 107 and is used to receive the laser signals emitted by the laser emitter 105, and determines the width of the roadway and the displacement of both sides by measuring the reflected light. The detection scale 107 is installed on both sides of the roadway, provides a fixed installation position for the photosensitive sensor 106, and serves as a reference for measuring displacement. Through the setting of the above components, real-time monitoring of the roadway surface can be realized, thereby improving the safety and efficiency of mine operations.

[0036] In some embodiments, there are at least two laser emitters 105, which are symmetrically distributed on both sides of the detection head 102 in the width direction of the roadway. The detection scale 107 is provided at the intersection position of the roof and the side of the roadway. The detection scale 107 is a cross-shaped scale, and the number of photosensitive sensors 106 is multiple, and at least one photosensitive sensor 106 is provided at the center position of the cross-shaped scale.

[0037] Two or more laser emitters 105 are symmetrically distributed along the width direction of the roadway, which helps to eliminate or reduce the measurement errors caused by the position offset of the emitters and improve the measurement accuracy. The cross-shaped scale is located at the intersection of the roof and the sidewall of the roadway and can serve as an accurate reference point, which helps to more accurately determine the projection position and angle of the laser beam. The use of multiple photosensitive sensors 106 can increase the redundancy of the system, ensuring that at least one sensor can work properly even under harsh or complex environmental conditions. Setting at least one photosensitive sensor 106 at the center position of the cross-shaped scale can ensure that the laser signal can be received even when the light conditions in the roadway are poor, thus improving the reliability of the system.

[0038] In some embodiments, the distance between adjacent two roadway surface detection components 1 along the roadway axis is 3m - 10m.

[0039] If the distance is too small, it may lead to repeated detections and increase the system complexity; if the distance is too large, it may lead to detection blind spots. The distance of 3m - 10m can ensure detection coverage while avoiding waste of resources. The roadway dimensions may vary due to geological conditions and design purposes. The interval range of 3m - 10m can adapt to roadways of different widths and heights, improving the versatility and flexibility of the system. A reasonable distance helps to improve the data acquisition speed on the premise of ensuring data quality, thus improving the efficiency of the entire detection system. An appropriate distance can reduce the mutual interference between adjacent detection components and the measurement errors caused by complex reflection and refraction phenomena in the roadway. The cost of the detection components and the installation and maintenance costs are factors to be considered in system design. By optimizing the distance, the system cost can be reduced while meeting the detection requirements.

[0040] In some embodiments, the detection device includes a plurality of concrete detection components 2, and the plurality of concrete detection components 2 are arranged in a rectangular array along the roadway axis direction in the concrete filling layer of the roadway sidewall.

[0041] By arranging the rectangular array of concrete detection components 2 in the concrete filling layer of the roadway sidewall, a comprehensive detection of the concrete layer of the roadway sidewall can be achieved, ensuring the quality and stability of the entire filling layer. The layout of multiple detection components can provide more data points, and the design of the rectangular array can be adjusted according to the size and shape of the roadway to adapt to different geological conditions and roadway structures. The layout of the rectangular array can detect multiple positions simultaneously, reducing the time consumption of a single detection point, thus improving the detection efficiency. The detection components of the rectangular array can adopt a unified data acquisition and processing system, which is convenient for centralized management and analysis of the data.

[0042] In some embodiments, the concrete detection assembly 2 includes a pallet 201, a first pressure sensor 202, and an elastic protective cover 203. The pallet 201 is provided with a receiving groove 2011 on at least one end surface in its thickness direction, at least a part of the first pressure sensor 202 is disposed in the receiving groove 2011, and the elastic protective cover 203 is covered on the first pressure sensor 202.

[0043] For example, as Figure 4 shown, the pallet 201 serves as the basis of the detection assembly, providing structural support and protecting the sensor from direct impact and external pressure. By providing the receiving groove 2011 on at least one end surface of the pallet 201, at least a part of the first pressure sensor 202 can be embedded therein, further protecting the sensor from the external environment. The design of the receiving groove 2011 helps to ensure the stable installation of the sensor and prevent the sensor position from shifting due to vibration or other factors during the detection process. The first pressure sensor 202 located in the receiving groove 2011 can more accurately measure the pressure change of the concrete filling layer, improving the sensitivity and accuracy of the detection. The elastic protective cover 203 covering the first pressure sensor 202 provides an additional protective layer to prevent concrete or other substances from directly contacting the sensor and protecting the sensor from wear or damage. The material and design of the elastic protective cover 203 need to be able to adapt to a certain degree of deformation without affecting the normal operation of the sensor.

[0044] Thus, the design of this concrete detection assembly 2, through the structures of the pallet 201, the receiving groove 2011, and the elastic protective cover 203, not only provides effective protection for the sensor, but also improves the stability, accuracy, and reliability of the detection system, thus providing strong support for the detection and evaluation of the roadway concrete structure.

[0045] In some embodiments, there are two pallets 201, which are connected by a spring piece 6, and the two pallets 201 are arranged within the same plane range of the concrete filling layer on the roadway sidewall.

[0046] As Figure 4 shown, the design of the two pallets 201 can provide a larger support area, increasing the overall stability of the detection assembly and helping to improve the accuracy of the measurement data. The connection of the spring piece 6 can provide a certain degree of flexibility, allowing the two pallets 201 to still maintain good contact and stability when the concrete filling layer on the roadway sidewall is uneven or has minor deformations. Through the elastic connection of the spring piece 6, the pallets 201 can adapt to different thicknesses of the concrete filling layer on the roadway sidewall, ensuring that the sensor can be correctly installed at the predetermined position under different construction conditions. The design of the two pallets 201 helps to evenly distribute the pressure, reducing sensor damage or data errors caused by local pressure concentration.

[0047] In some embodiments, the anchor cable detection assembly 3 includes a bearing plate 301, a mounting bracket 302, a fixed buckle 303, a movable buckle 304, a second pressure sensor 305, and a third pressure sensor 306. The bearing plate 301 is used to connect to the roadway sidewall. The bearing plate 301 has a first through hole 3011. The mounting bracket 302 is connected to the bearing plate 301 and defines an installation space 8. The fixed buckle 303 is disposed in the installation space 8 and connected to the mounting bracket 302. The movable buckle 304 is disposed in the installation space 8 and is disposed closer to the roadway sidewall than the fixed buckle 303. The movable buckle 304 is slidably connected to the fixed buckle 303. The second pressure sensor 305 is disposed between the movable buckle 304 and the bearing plate 301. The third pressure sensor 306 is disposed between the movable buckle 304 and the fixed buckle 303. The anchor cable passes through the first through hole 3011 and is connected to the movable buckle 304.

[0048] The bearing plate 301 is used to connect to the roadway sidewall. It provides a stable platform for transmitting the tensile force of the anchor cable to the roadway sidewall. The first through hole 3011 allows the anchor cable to pass through and be connected to the movable buckle 304. The design of the fixed buckle 303 and the movable buckle 304 allows the movable buckle 304 to slide relative to the fixed buckle 303 when the anchor cable is subjected to a tensile force, so that the movement and force-bearing conditions of the anchor cable in actual use can be simulated. The second pressure sensor 305 is located between the movable buckle 304 and the bearing plate 301 and is used to measure the pressure of the anchor cable on the bearing plate 301, that is, the pre-tightening force or working load of the anchor cable. The third pressure sensor 306 is located between the movable buckle 304 and the fixed buckle 303 and is used to measure the pressure change caused by the relative displacement between the movable buckle 304 and the fixed buckle 303 due to the force on the anchor cable, which helps to analyze the tensile and compression conditions of the anchor cable. The anchor cable passes through the first through hole 3011 of the bearing plate 301 and is connected to the movable buckle 304. In this way, when the anchor cable is subjected to a force, the bearing plate 301, the movable buckle 304, and the sensors will all be subjected to the force accordingly, so that the working state of the anchor cable can be detected.

[0049] Based on the data of the second pressure sensor 305 and the third pressure sensor 306, the force-bearing condition of the anchor cable can be detected in real time, providing data support for the safety assessment of the roadway. Detecting abnormal changes in the force on the anchor cable in a timely manner can prevent potential safety accidents and ensure the stability of the roadway and the safety of the operating personnel. The design and installation position of the sensors can accurately measure the force on the anchor cable, providing a basis for the tensioning and locking of the anchor cable. The design of this detection assembly can adapt to different roadway conditions and anchor cable systems and has good versatility.

[0050] In some embodiments, a fourth pressure sensor 7 is provided on the end face of the bearing plate 301 adjacent to the roadway sidewall.

[0051] The fourth pressure sensor 7 is installed on the end face of the bearing plate 301 adjacent to the roadway side. Such a position selection helps to directly detect the pressure change of the concrete filling layer on the roadway side, because this area is a key part of the roadway support structure that bears pressure, which is crucial for evaluating the stability and bearing capacity of the concrete layer. By detecting the pressure change of the concrete filling layer, pressure anomalies caused by factors such as roadway excavation, blasting operations, and groundwater level changes can be discovered in a timely manner, so as to take corresponding measures to prevent roadway deformation or damage.

[0056] S4, data analysis. According to the detected data, the damage state of the roadway is analyzed, and the analysis results are promptly summarized and reported. At the same time, the roadway support structure is repaired and maintained according to the detection results.
