Description

Technical Field

[0001] This application relates to the technical field of mine testing equipment, and in particular to a device for monitoring the geological environment of mines. Background Technology

[0002] Mine geological environment monitoring refers to the regular and systematic observation, monitoring, and evaluation of the mine geological environment to understand the changing patterns and trends of the mining area's geological environment, providing a scientific basis for decision-making in mine operation and management, environmental protection, and other aspects. Its importance cannot be ignored because mining activities have a profound impact on the surrounding environment.

[0003] Ground-based ground-penetrating radar (GPR) is the most widely used method of observation. It transmits high-frequency electromagnetic waves into the ground using a transmitter and antenna. These waves reflect off interfaces where there are significant electrical differences between the soil and rock strata. The echo signals are received on the ground by a receiver and antenna, and then processed, interpreted, and mapped to obtain images of the underground geological structure and depth data. When detecting mine slopes, GPR is typically secured to the ground using pins. To reduce the impact of the external environment, a simple protective casing is usually used. However, during continuous rainy weather, rainwater washes away the slope surface, and the flowing water carries rocks, easily damaging the casing. When the detection location is at the bottom of the mine slope, the GPR is easily covered by rocks and other debris as they accumulate, making equipment retrieval very difficult. Therefore, there is still room for improvement. Summary of the Invention

[0004] In order to improve the protection effect of ground-penetrating radar and reduce the probability of ground-penetrating radar being covered by rocks, this application provides a device for monitoring the geological environment of mines.

[0005] The device for monitoring the geological environment in mines provided in this application adopts the following technical solution:

[0006] A device for monitoring the geological environment of a mine, comprising:

[0007] The ground-penetrating radar consists of a main body, an outer shell, a baffle strip, and an external support frame. The outer shell covers the radar main body, the baffle strip surrounds the perimeter of the outer shell, and the external support frame is inserted into the surface of the mine slope and fixes the baffle strip.

[0008] By adopting the above technical solution, the outer shell and the baffle strip serve as two lines of defense to protect the ground-penetrating radar. The baffle strip, as the first line of defense, can create a closed protective area at the detection location on the mine slope, blocking water flow and most falling rocks to reduce the possibility of rock pile formation. The outer shell, as the second line of defense, can block falling rocks from entering the protected area, which helps reduce the probability of damage to the ground-penetrating radar. The setting of two lines of defense helps to improve the protection effect of the ground-penetrating radar and reduce the probability of the ground-penetrating radar being covered by rocks, making it easier to maintain the integrity of the ground-penetrating radar and to facilitate the retrieval of the ground-penetrating radar by the detection personnel. In addition, the use of an external bracket to support and fix the baffle strip helps to improve the stability of the baffle strip. In this solution, the baffle strip, external bracket, and outer shell are all simple structures, which are easy to carry and install.

[0009] Preferably, the external support includes a plurality of positioning rods, the plurality of positioning rods being perpendicular to the surface of the mine slope, and the partition strip being sleeved between the plurality of positioning rods.

[0010] By adopting the above technical solution, the positioning rod serves as the fulcrum of the partition belt, which helps the partition belt maintain a certain shape and is easy to install, thereby improving the stability and installation efficiency of the partition belt.

[0011] Preferably, the partition strip is triangularly arranged around the periphery of the outer shell, with one corner of the triangular area enclosed by the partition strip facing the top of the mine slope.

[0012] By adopting the above technical solution, the two hypotenuses of the triangular area enclosed by the barrier strip serve as guiding surfaces, which facilitates the guidance of falling rocks and water flow to both sides, thereby reducing the situation of rock accumulation and the situation of falling rocks remaining outside the barrier strip.

[0013] Preferably, the external bracket further includes a plurality of diagonal braces, each of which corresponds to a plurality of positioning rods. The top of each positioning rod is provided with a positioning hole, and the diagonal brace is obliquely inserted into the positioning hole of the corresponding positioning rod. The inclined lower end of the diagonal brace is inserted into the mine slope, and the inclined upper ends of the plurality of diagonal braces converge above the outer shell. Connecting members are connected between the inclined upper ends of the plurality of diagonal braces.

[0014] By adopting the above technical solution, a stable triangular structure is formed between each pair of diagonal braces, and the diagonal braces are kept in an inclined state through the positioning holes of the positioning rods. At the same time, the connection stability between the positioning rods and the diagonal braces is improved, which is conducive to improving the stability of the partition strip.

[0015] Preferably, the external bracket further includes a plurality of U-shaped inserts, each of which corresponds to a plurality of diagonal braces. The diagonal braces pass through the inner side of the corresponding U-shaped inserts, and the ends of the U-shaped inserts are inserted into the surface of the mine slope inside the partition strip. The plurality of U-shaped inserts surround the periphery of the outer shell.

[0016] By adopting the above technical solution, the U-shaped insert rods limit the diagonal bracing rods, further improving the stability of the diagonal bracing rods. Several of the U-shaped insert rods are inserted into the surface of the mine slope inside the barrier zone and surround the outer shell, forming a third line of defense inside the barrier zone. This can block falling rocks that jump into the inner side of the barrier zone, which helps to reduce the impact of falling rocks on the ground radar body.

[0017] Preferably, the outer side of the outer shell is provided with a plurality of connecting rings, and the plurality of connecting rings correspond one-to-one with a plurality of U-shaped inserts, the U-shaped inserts passing through the corresponding connecting rings and being inserted into the mine slope.

[0018] By adopting the above technical solution, the outer shell is fixed to the mine slope, which helps to improve the stability of the shell.

[0019] Preferably, the outer side of the partition strip is provided with several protrusions.

[0020] When the barrier belt is made of non-rigid materials such as belts, direct impact of falling rocks can easily cause wear on the outer side of the barrier belt, and it is prone to breakage under repeated use. By adopting the above technical solution, several protrusions are arranged on the inner side of the barrier belt. When falling rocks hit the barrier belt, the protrusions play a blocking role, reducing the probability of direct contact between falling rocks and the barrier belt, which helps to reduce the wear of the barrier belt and facilitates the reuse of the barrier belt.

[0021] Preferably, each of the positioning rods has a roller rotatably connected to its outer circumferential surface, and the partition belt is sleeved between the rollers.

[0022] By adopting the above technical solution, the barrier belt rotates when subjected to external impact, thereby achieving a force-dissipating effect and helping to reduce the damage to the barrier belt caused by falling rocks.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Two lines of defense are set up around the ground-penetrating radar body. The first line of defense is a barrier strip that encloses a protective area at the detection location on the mine slope to block water flow and most falling rocks, reducing the possibility of rock pile formation. The outer shell serves as the second line of defense, which can block falling rocks from jumping into the protective area, thus reducing the probability of damage to the ground-penetrating radar body. The two lines of defense reduce the probability of the ground-penetrating radar being covered by rocks, making it easier for the detection personnel to retrieve the ground-penetrating radar body. In addition, the use of external brackets to support and fix the barrier strip helps to improve the stability of the barrier strip.

[0025] 2. By using positioning rods, U-shaped inserts, and diagonal braces to form a stable triangular structure, and simultaneously fixing the baffle and the outer shell, the overall stability of the mine geological environment monitoring device is improved. The U-shaped inserts are inserted into the mine slope surface inside the baffle and surround the outer shell. The U-shaped inserts form a third line of defense inside the baffle, which can block falling rocks that jump into the inner side of the baffle, thus reducing the impact of falling rocks on the ground radar body.

[0026] 3. Several protrusions are arranged on the outer side of the barrier to block and reduce the probability of direct contact between falling rocks and the barrier, which helps to reduce wear and tear on the barrier and facilitates its reuse. By setting rollers on the positioning rod, the barrier rotates when subjected to external impact, thereby relieving the force and reducing damage to the barrier from falling rocks.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a device for monitoring the geological environment of a mine, specifically for monitoring in continuous rainy weather and at the bottom of a mine slope 1. (Refer to...) Figure 1 and Figure 2 A device for monitoring the geological environment of a mine includes a ground-penetrating radar body 5, an outer casing 4, a baffle strip 2, and an external support 3. When detecting ore geology, the ground-penetrating radar is placed on the surface of the mine slope 1, then the outer casing 4 is placed over the radar body, and the baffle strip 2 is placed around the outer casing 4. The external support 3 is inserted into the surface of the mine slope 1 and fixes the baffle strip 2.

[0033] Specifically, refer to Figure 1 and Figure 3 The external support 3 includes three positioning rods 33, three diagonal bracing rods 32, and three U-shaped insert rods 31. The three positioning rods 33 are vertically inserted into the surface of the mine slope 1. Each positioning rod 33 has a roller 332 rotatably connected to its outer circumference. An annular baffle 2 is fitted between the three rollers 332 and arranged in an equilateral triangle. One corner of the triangular area enclosed by the baffle 2 faces the top of the mine slope 1, so that the two hypotenuses of the triangular area enclosed by the baffle 2 serve as guiding surfaces, which facilitates the guidance of falling rocks and water flow to both sides, reducing the accumulation of rocks and the amount of falling rocks left outside the baffle 2.

[0034] The outer and inner circumferential surfaces of the baffle belt 2 are evenly distributed with several protrusions 21. When falling rocks impact the baffle belt 2, the protrusions 21 on the outer side of the baffle belt 2 act as a barrier, reducing the probability of direct contact between the falling rocks and the baffle belt 2, which helps to reduce wear on the baffle belt 2. In continuous rainy weather, the water flow mixed with rocks continuously impacts the baffle belt 2 and the protrusions 21. The baffle belt 2 can rotate under the linkage of the roller 332, thereby achieving a force-dissipating effect and helping to reduce damage to the baffle belt 2 from falling rocks. Since some rocks may jump into the inner side of the baffle belt 2, which can easily cause the falling rocks to be squeezed inside the baffle belt 2, a discharge chute 11 is excavated at the mine slope 1. The discharge chute 11 is located below the baffle belt 2. Part of the discharge chute 11 is located within the area enclosed by the baffle belt 2. Falling rocks can be discharged from the discharge chute 11 outside the baffle belt 2 under their own weight, which helps to reduce the accumulation of falling rocks inside the baffle belt 2. A protrusion 21 is provided on the inner side of the baffle belt 2. When the protrusion 21 on the outer side of the baffle belt 2 is hit by falling rocks, it can drive the baffle belt 2 to rotate, thereby causing the protrusion 21 on the inner side of the baffle belt 2 to move, and then causing the falling rocks stuck between the inner wall of the unloading chute 11 and the inner side of the baffle belt 2 to fall into the unloading chute 11, which is conducive to the normal discharge of falling rocks on the inner side of the baffle belt 2.

[0035] To reduce the impact of the inner protrusion 21 of the partition belt 2 on the normal rotation of the partition belt 2, an annular groove 333 is provided on the outer wall of the roller 332. The annular groove 333 allows the inner protrusion 21 of the partition belt 2 to pass through, which helps to maintain the smooth rotation of the partition belt 2.

[0036] In this embodiment, three diagonal braces 32 correspond one-to-one with three positioning rods 33. Positioning rods 33 have positioning holes at their tops, and the diagonal braces 32 are obliquely inserted through the corresponding positioning holes of the positioning rods 33. The lower inclined ends of the diagonal braces 32 are inserted into the mine slope 1, and the upper inclined ends of the three diagonal braces 32 converge directly above the outer casing 4. Connectors 34 connect the upper inclined ends of the three diagonal braces 32. In this embodiment, the connector 34 is a rubber plug with three connecting holes on its outer wall. These three connecting holes correspond one-to-one with the three diagonal braces 32, and the upper inclined ends of the diagonal braces 32 are inserted into the corresponding connecting holes. The connector 34 connects the three diagonal braces 32 to form a triangular support system, facilitating force transmission when impacted by falling rocks and maintaining the overall balance and stability of the mine geological environment monitoring device.

[0037] In this embodiment, three U-shaped inserts 31 correspond one-to-one with three diagonal braces 32. The diagonal braces 32 pass through the inner side of the corresponding U-shaped inserts 31, and the ends of the U-shaped inserts 31 are inserted into the surface of the mine slope 1 on the inner side of the retaining strip 2. The inner side of the U-shaped inserts 31 presses down on the outer circumference of the diagonal braces 32 towards the mine slope 1 to improve the tightness between the U-shaped inserts 31 and the diagonal braces 32. In addition, the U-shaped inserts 31 are provided with pins, which are horizontally inserted through the two vertical sections of the U-shaped inserts 31, thereby restricting the diagonal braces 32 in the restrictive holes formed by the inner side of the U-shaped inserts 31 and the pins, which helps to improve the connection stability between the diagonal braces 32 and the U-shaped inserts 31.

[0038] Reference Figure 1 and Figure 2 The vertical sections of the three U-shaped rods 31 converge toward the outer shell 4. Three connecting rings 41 are fixed to the outer wall of the outer shell 4. The three connecting rings 41 correspond one-to-one with the three U-shaped rods 31. The U-shaped rods 31 first pass through the corresponding connecting rings 41 and then insert into the mine slope 1, thereby stabilizing the outer shell 4 on the surface of the mine slope 1. The three U-shaped rods 31 surround the outer shell 4, thereby forming a third line of defense inside the barrier 2, which can block falling rocks that jump into the inner side of the barrier 2, and help reduce the impact of falling rocks on the ground radar body 5.

[0039] The implementation principle of a device for monitoring the geological environment in mines according to an embodiment of this application is as follows:

[0040] When installing the mine geological environment monitoring device, mark the installation positions of the ground-penetrating radar body 5 and the three positioning rods 33 at the mine slope 1, and excavate a discharge chute between the installation marks of the two lower positioning rods 33. Then, place the ground-penetrating radar body 5 at the marked point in the detection area of ​​the mine slope 1, and insert the positioning rods 33 into the mine slope 1 in a direction perpendicular to the surface of the mine slope 1. Then, cover the outside of the ground-penetrating radar body 5 with the outer shell 4, and fit the annular partition belt 2 between the rollers 332 of the three positioning rods 33.

[0041] Then, the diagonal bracing rods 32 are installed. The diagonal bracing rods 32 pass through the positioning holes on the corresponding positioning rods 33, and the inclined lower ends of the diagonal bracing rods 32 are inserted into the mine slope 1. The inclined upper ends of the three diagonal bracing rods 32 converge above the outer shell 4 and are connected and fixed by rubber plugs, thus forming a triangular support system.

[0042] Next, the U-shaped insert rods 31 are installed. The vertical sections of the three U-shaped insert rods 31 converge towards the outer shell 4. The U-shaped insert rods 31 are engaged with the corresponding diagonal braces 32. The vertical section of the U-shaped insert rod 31 passes through the corresponding connecting ring 41 before being inserted into the mine slope 1, thereby stabilizing the outer shell 4 on the surface of the mine slope 1. Finally, the pin is fixed to the U-shaped insert rod 31. The positioning rod 33, the U-shaped insert rod 31, and the diagonal braces 32 form a stable triangular structure, which simultaneously fixes the partition strip 2 and the outer shell 4, thus improving the overall stability of the mine geological environment monitoring device.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
