Description

Technical Field

[0001] The present invention relates to the technical field of mine rock support, and in particular to a mine rock support monitoring system and method. Background Art

[0002] Mine tunnel roof disasters are usually caused by a variety of factors, among which the geological environment of the mine, such as the stability of the rock layer, the thickness and inclination of the rock layer, the distribution of faults and joints, etc., will directly affect the safety of the roof. Unstable geological conditions may cause the roof rock layer to loosen and break, reducing its bearing capacity. In addition, special parts such as tunnel intersections and turning points are prone to stress concentration due to sudden changes in geometric shapes, making the roof of these parts more prone to disasters.

[0003] In the related technologies, tunnel support is generally reinforced by anchoring, that is, using materials such as anchor rods, anchor cables, and prestressed components to fix structures or rock masses through drilling and anchoring technology to improve their stability and bearing capacity. Under the action of tectonic stress and mining stress, the tunnel rock strata are prone to settlement due to internal shear dislocation. The anchor rods or anchor cables in the related technologies cannot warn of changes in the rock strata, resulting in no effective warning when the tunnel rock strata undergoes settlement and other changes, which can easily lead to tunnel accidents.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] The following describes a mine rock support monitoring system according to an embodiment of the present invention with reference to the accompanying drawings.

[0039] like Figure 1-Figure 4 As shown, the mine rock support monitoring system according to an embodiment of the present invention includes a driving component 1 , a scanning component 2 and a monitoring component 3 .

[0040] The driving member 1 includes a driving base 11 and a moving part 12, the moving part 12 is connected to the driving base 11, and the moving part 12 is movable relative to the driving base 11. It is understandable that the moving part 12 can be a device with a reciprocating function such as a cylinder, an oil cylinder, and a linear module, so that the monitoring member 3 can be installed in the anchor hole. The driving base 11 is provided with a cylinder, an oil cylinder, etc., so that the driving base 11 can be movable in the vertical direction relative to the ground, thereby realizing the function of adjusting the height of the driving base 11. Optionally, the driving member 1 can also be an anchor bolt machine, that is, the telescopic function of the anchor bolt machine is used to realize the installation of the monitoring member 3.

[0041] The scanner 2 is connected to the driving base 11. The scanner 2 includes an information processing unit and a visual scanning unit. The visual scanning unit is used to determine the monitoring area 200 and the monitoring point 300. The monitoring point 300 is placed in the monitoring area 200. The monitoring area 200 includes an area surrounded by multiple anchor points 100. The multiple anchor points 100 are divided into multiple anchor groups. An anchor group includes multiple anchor points 100. In two adjacent anchor groups, the extension direction of the connection line between the multiple anchor points 100 in one anchor group and the extension direction of the connection line between the multiple anchor points 100 in the other anchor group have an angle. The monitoring point 300 is provided with an anchor hole, and the distance between the monitoring point 300 and the multiple anchor points 100 in one monitoring area 200 is equal.

[0042] Specifically, Figure 1-Figure 4 As shown, the visual scanning unit is located at the upper end of the driving base 11 to facilitate scanning of the anchor point 100 position on the rock wall of the mine. It is understandable that the visual scanning unit includes a camera or a visual sensor for capturing images or video data within the monitoring area 200. The information processing unit includes modules such as data processing, data analysis, and data transmission to receive information transmitted by the visual scanning unit and process the information, that is, it can determine the monitoring area 200 based on the information collected by the visual scanning unit, and determine the monitoring point 300 based on the position of each anchor point 100 in the monitoring area 200, so as to drill the monitoring point 300 using a drilling rig. Preferably, the scanner 2 is electrically connected to the control room so that the control room can receive the rock formation status when the scanner 2 is working in real time.

[0043] It should be noted that if Figure 4 As shown, the area surrounded by four anchor points 100 is a monitoring area 200, and one anchor group includes two anchor points 100. In two adjacent anchor groups, the extension direction of the line between the two anchor points 100 is at a certain angle, and the distance from the monitoring point 300 located in the middle of the monitoring area 200 to each anchor point 100 in the monitoring area 200 is equal. Therefore, the monitoring component 3 is placed in the borehole at the position of the monitoring point 300, so that the monitoring component 3 monitors each adjacent anchor point at the same time, and because the distance between the monitoring component 3 and each anchor point 100 is equal, when the mine rock formation settles or water inrush occurs inside the rock formation, the monitoring component 3 can quickly obtain feedback information and transmit it to the control room through the information processing unit, thereby realizing early warning of rock formation disasters.

[0044] The monitoring component 3 is used to be installed in the anchor hole. The monitoring component 3 includes a monitoring body 31, a first monitor 315 and a second monitor 316. The first monitor 315 and the second monitor 316 are both connected to the monitoring body 31, and the first monitor 315 and the second monitor 316 are arranged in sequence along the length direction of the monitoring body 31. The first monitor 315 is used to monitor the vibration of the rock mass, and the second monitor 316 is used to monitor the water inrush in the anchor hole.

[0045] It is understandable that if Figure 1-Figure 3 As shown, the monitoring body 31 is installed in the borehole, and the outer peripheral wall of the monitoring body 31 contacts the inner wall surface of the borehole to ensure that the monitoring component 3 can be firmly installed in the anchor hole while remaining stable to withstand rock vibration and potential water inrush pressure.

[0046] The first monitor 315 may be a vibration sensor, which can capture vibration signals generated by rock mass due to stress changes. The vibration sensor may be a piezoelectric sensor, an electromagnetic sensor or other types of sensors, which can convert vibration into electrical signals for analysis by the information processing unit.

[0047] The second monitor 316 may be a liquid level sensor or a pressure sensor, which is used to detect the level or pressure change of the liquid in the anchor hole. That is, the liquid level sensor may work in an ultrasonic, capacitive or float manner to monitor the occurrence and extent of water inrush. The pressure sensor may measure the change of water pressure to determine whether water is flowing into the anchor hole.

[0048] Therefore, the mine rock support monitoring system of the embodiment of the present invention can set the monitoring area 200 according to the anchoring area in the mine tunnel, and drill a hole at the monitoring point 300 determined in the monitoring area 200, and then place the monitoring device 3 in the borehole to realize real-time monitoring of the rock vibration and water inrush in the borehole, so that early warning can be issued according to the changes in the rock formation to avoid the occurrence of tunnel accidents.

[0049] In some embodiments, the monitoring body 31 has a drainage channel 3121, the extension direction of the drainage channel 3121 is consistent with the length direction of the anchor hole, the second monitor 316 is arranged in the drainage channel 3121, the monitoring body 31 has a first drainage channel 3122, the first drainage channel 3122 passes through the side wall of the monitoring body 31 and is connected to the drainage channel 3121, the axial direction of the first drainage channel 3122 has an angle with the radial direction of the monitoring body 31, there are multiple first drainage channels 3122, and the multiple first drainage channels 3122 are arranged at intervals along the circumference of the monitoring body 31.

[0050] Specifically, Figure 2 and Figure 3As shown, the extension direction of the monitoring component 3 is consistent with the extension direction of the anchor hole, and the opening of the drainage channel 3121 is located at the left end of the monitoring component 3. The liquid in the anchor hole can be discharged through the first drainage channel 3122 and the drainage channel 3121, so that the construction personnel in the tunnel can observe it in time.

[0051] It can be understood that the first drainage channels 3122 are arranged at intervals along the circumference of the monitoring body 31, which can facilitate the liquid existing around the monitoring device 3 in the anchor hole to flow to the drainage channel 3121 through multiple drainage channels. The liquid collected in the drainage channel 3121 can be discharged from the opening of the drainage channel 3121, making it easier for construction personnel to observe.

[0052] like Figure 2 and Figure 3 As shown, the radial direction of the monitoring body 31 is orthogonal to the left and right direction, and the angle between the axial direction of the first drainage channel 3122 and the radial direction of the monitoring body 31 is α, that is, the first drainage channel 3122 is arranged obliquely, which can effectively prevent the stones in the anchor hole from directly falling into the drainage channel 3121 through the first drainage channel 3122, and larger stones are easily accumulated at the outer port of the first drainage channel 3122, which can not only block other stones from falling in, but also there is a gap between the stones and the first drainage channel 3122, which is also convenient for the flow of liquid in the anchor hole.

[0053] Preferably, in the direction from the opening of the anchor hole to the end of the anchor hole, the cross-sectional area of ​​the first drainage channel 3122 gradually decreases. It can be understood that the cross-sectional area of ​​the first drainage channel 3122 gradually decreases from left to right, so that after the monitoring element 3 is inserted horizontally or obliquely upward into the anchor hole, it is easier for the liquid in the drainage channel 3121 to flow out, thereby ensuring that the construction personnel can observe the changes in the water inrush of the anchor hole more quickly.

[0054] In some embodiments, in the direction from the mouth of the anchor hole to the tail of the anchor hole, the monitoring body 31 includes a connecting section 311, a drainage section 312 and a monitoring section 313 connected in sequence, and the monitoring section 313 has an annular groove 3131, and the annular groove 3131 is opened on the wall surface of the monitoring section 313 along the circumference of the monitoring section 313, and the first monitor 315 is arranged in the annular groove 3131; the monitoring component 3 also includes a cover plate 314, the cover plate 314 is connected to the monitoring section 313 and is adapted to the annular groove 3131, and there are multiple cover plates 314, and the multiple cover plates 314 are arranged at intervals along the circumference of the monitoring section 313.

[0055] Specifically, Figure 2 and Figure 3As shown, the annular groove 3131 is located at the right part of the monitoring section 313, and the right part of the monitoring section 313 is provided with a chamfer to facilitate the insertion of the monitoring member 3 into the anchor hole. It can be understood that there can be multiple first monitors 315, and multiple first monitors 315 are arranged in the annular groove 3131 at intervals, and the annular groove 3131 provides installation space for the first monitor 315. There are multiple cover plates 314, and multiple cover plates 314 are arranged in the annular groove 3131 at intervals along the circumference of the monitoring section 313, and the multiple cover plates 314 correspond to the multiple first monitors 315 one by one, so as to provide shielding for the first monitors 315.

[0056] That is to say, multiple first monitors 315 are installed in the annular groove 3131, and multiple cover plates 314 are used to cover the multiple first monitors 315 respectively, so as to prevent rocks with pointed ends or sharp end faces from contacting the first monitors 315 during the detection process, thereby preventing the first monitors 315 from being damaged, thereby improving the service life of the monitoring component 3.

[0057] In addition, if Figure 2 and Figure 3 As shown, the drainage channel 3121 is placed in the connecting section 311 and the drainage section 312, that is, the connecting section 311 and the drainage section 312 are hollow structures, while the monitoring section 313 is a solid structure, which not only provides a flow channel for drainage of the anchor hole, but also ensures the overall rigidity of the monitoring section 313, improves the deformation resistance of the monitoring section 313, and further ensures the monitoring time of the first monitor 315 and the effectiveness of information feedback.

[0058] In some embodiments, the monitoring unit further includes an elastic member 317, and the elastic member 317 connects the cover plate 314 and the bottom wall of the annular groove 3131. Figure 2 and Figure 3 As shown, when the monitoring section 313 is squeezed by the rock mass, the cover plate 314 will directly squeeze the first monitor 315 located in the annular groove 3131, and the elastic member 317 is connected between the cover plate 314 and the bottom wall of the annular groove 3131, which can slow down the squeezing of the first monitor 315 by the cover plate 314, thereby ensuring the monitoring time of the first monitor 315.

[0059] In some embodiments, the monitoring body 31 further has a second drainage channel 3132 , which passes through the bottom wall of the annular groove 3131 and is connected to the drainage channel 3121 . There are multiple second drainage channels 3132 , which are arranged at intervals along the circumference of the monitoring section 313 .

[0060] Understandable, such as Figure 2 and Figure 3As shown, since there is a gap between the cover plate 314 and the annular groove 3131, after water burst occurs in the anchor hole, the liquid can flow into the annular groove 3131, and the multiple second drainage channels 3132 can introduce the liquid in the annular groove 3131 into the drainage channel 3121, thereby preventing the liquid in the anchor hole from accumulating in the annular groove 3131, which not only ensures that the water burst in the anchor hole is discharged in time to warn the construction personnel, but also ensures the working environment of the first monitor 315.

[0061] In some embodiments, the monitoring component 3 also includes a blocking protrusion 318, which is connected to the drainage section 312 and arranged adjacent to the first water diversion channel. The blocking protrusion 318 is located on the side of the opening of the first water diversion channel adjacent to the anchor hole. The blocking protrusion 318 is arranged along the circumference of the drainage section 312, the monitoring unit is placed in the anchor hole, and the blocking protrusion 318 is against the inner wall surface of the anchor hole.

[0062] Specifically, Figure 2 and Figure 3 As shown, the blocking protrusion 318 is located on the left side of the first channel, and the monitoring component 3 is placed in the anchor hole. The blocking protrusion 318 can be against the wall of the anchor hole to ensure that the liquid in the anchor hole quickly accumulates on the right side of the blocking protrusion 318 and flows into the drainage channel 3121 through the first drainage channel 3122 and the second drainage channel 3132, so that the liquid in the anchor hole is quickly gathered and discharged, which is convenient for observation by construction personnel.

[0063] like Figure 2 and Figure 3 As shown, the blocking protrusion 318 can be annular, and the blocking protrusion 318 can be made of soft rubber material to improve the sealing performance between the blocking protrusion 318 and the wall of the anchor hole. It can be understood that the blocking protrusion 318 is arranged near the opening of the first drainage channel 3122, so that the stone in the anchor hole falls near the opening of the first drainage channel 3122 and can overlap on the blocking protrusion 318, thereby increasing the gap between the stone and the opening of the first drainage channel 3122, which is more convenient for the flow of liquid.

[0064] In some embodiments, the monitoring component 3 also includes a sealing component 319, which includes a connecting portion 3191 and a fixing portion 3192. The connecting portion 3191 is detachably connected to the connecting section 311, and the fixing portion 3192 is connected to the connecting portion 3191, and the fixing portion 3192 is arranged along the circumference of the connecting portion 3191. In the direction from the mouth of the anchor hole to the tail of the anchor hole, the radial size of the connecting portion 3191 gradually decreases.

[0065] Specifically, Figure 2 and Figure 3As shown, the fixing portion 3192 is annular, and the connecting portion 3191 and the fixing portion 3192 can be connected by welding, or the connecting portion 3191 and the fixing portion 3192 can be integrally cast. The connecting portion 3191 and the connecting section 311 can be detachably connected by snap connection or thread connection. A plurality of connecting holes are provided on the connecting portion 3191. After the fixing portion 3192 and the connecting section 311 are connected, the plugging member 319 can be fixed to the rock wall through the connecting holes by screws or the like.

[0066] It can be understood that the radial dimension of the connection portion 3191 gradually decreases from left to right, so that when the monitoring member 3 is inserted into the anchor hole from right to left, the connection portion 3191 and the orifice of the anchor hole are engaged by extrusion and friction, thereby preventing the monitoring member 3 from being easily separated from the anchor hole. The following describes a mine rock support monitoring method according to an embodiment of the present invention.

[0067] The mine rock support monitoring method of the embodiment of the present invention is implemented by using the mine rock excavation system according to any one of the above embodiments, and includes the following steps:

[0068] Determine the location of the anchor point of the mine rock wall and define the monitoring area. That is, according to the anchor point of the rock wall in the mine, use the scanner to scan and record part of the anchor area on the rock wall and determine the monitoring range (i.e. monitoring area).

[0069] The monitoring point is determined according to the position of the anchor point in the monitoring area. According to the range of the monitoring area recorded in the visual scanning unit, the information processing unit is used to locate the anchor point position in the area, and then a monitoring point is determined so that the monitoring point is at the same distance from the anchor point in the monitoring area. A laser transmitter can also be installed on the driving base. After the monitoring point is determined, the laser transmitter is used to mark the monitoring point to facilitate subsequent drilling.

[0070] Drill holes at the locations of the determined monitoring points. You can use an anchor bolter or a drilling rig to drill holes at the determined monitoring points.

[0071] Install the monitoring component in the drilled hole. Adjust the height of the driving base and insert the monitoring component into the drilled hole using the moving part.

[0072] The first monitor and the second monitor are used to respectively monitor the rock mass vibration and water inrush in the borehole in real time.

[0073] In some embodiments, the mine rock support monitoring method of the embodiment of the present invention further includes the following steps: if the monitoring information monitored by at least one of the first monitor and the second monitor exceeds a preset safety threshold, a warning signal is issued.

[0074] It is understandable that a warning device, such as a buzzer, a warning light, etc., can be set on the monitoring device, or a warning device can be set in the control room. When the information monitored by the monitoring device exceeds the preset safety threshold, a start signal is sent to the warning device, so that the warning device can send a warning signal to alert the construction personnel in the control room and the mine.
