Abstract
Description
Technical Field
[0002] This invention relates to the field of environmental monitoring technology in mining, specifically to a segmented environmental monitoring device and method for mining. Background Technology
[0003] During mining operations, monitoring environmental parameters within roadways and rock masses is crucial for ensuring mining safety and preventing geological disasters. This requires precise collection of environmental data and rock sample indicators at different depths and sections within the rock mass, including rock temperature, humidity, harmful gas concentrations, and physical properties of the rock samples. Existing mine environmental monitoring devices are mostly surface-based or perform borehole drilling at single depths, making it difficult to achieve segmented, simultaneous monitoring of the rock mass along the drilling direction. This results in low monitoring efficiency and insufficient data comprehensiveness and accuracy, failing to provide multi-dimensional geological environmental data support for safety assessments of mining operations.
[0004] A search revealed a Chinese invention patent with authorization announcement number CN115014840B, which discloses a device for monitoring the geological environment in mines. Although it can achieve deep borehole monitoring of mine geology, it can only collect overall environmental data at the drilling location and does not have an independent sampling and testing structure for different segments inside the rock mass. It cannot complete the synchronous testing of multiple rock samples along the drilling axis, making it difficult to obtain differentiated environmental data at different depths of the rock mass. Therefore, it cannot meet the actual needs of segmented environmental monitoring of rock mass in mining operations. Summary of the Invention

The second power output end 6 is composed of a rotating shaft.
[0008] Preferably, the diameter of the first gear is greater than the diameter of the first transmission gear, the diameter of the second transmission gear is greater than the diameter of the first gear, and the diameter of the second gear is less than the diameter of the first transmission gear.
[0009] Preferably, the spiral conveying mechanism includes a round shaft detachably connected to the end of the rotating shaft, and a spiral blade fixedly disposed on the circumferential side of the round shaft. The spiral blade is located in the inner cavity of the drill bit, and the spiral blade is provided with a material accumulation structure for slowing down the axial movement speed of the material in a local area.
[0010] Preferably, the material accumulation structure is configured as a variable torque structure of a spiral blade, wherein the distance between two adjacent blades of the spiral blade gradually increases from the middle position of the sample detection partition to the sampling port and the sample outlet on both sides, and the second sensor is fixedly installed on the material accumulation structure on the spiral blade.
[0011] Preferably, the drill bit is configured as a conical drill body with its diameter gradually decreasing from near the control box to far away from the control box. An L-shaped shovel is provided on the circumferential side of the drill bit at the sampling port of each sample detection compartment. The projection of the L-shaped shovel towards the sampling port is larger than the area of the sampling port. A mounting cavity is coaxially opened at the end of the drill bit with a smaller diameter, and the first sensor is disposed in the mounting cavity.
[0012] Preferably, the plurality of sample detection partitions are separated by at least one annular gasket coaxial with the circular shaft, and the annular gasket slides in contact with the inner wall of the drill bit; The sampling port is opened through the peripheral side of each sample detection compartment near the side with the smaller diameter of the drill bit; The sample outlet is opened through the peripheral side of each sample detection compartment near the side with the larger diameter of the drill bit; Along the axial direction of the drill bit, the outlet on each of the sample detection compartments is further away from the smaller diameter end of the drill bit relative to the sampling port on the sample detection compartment.
[0013] Preferably, the mounting frame is configured as a cross-shaped structure, which includes two vertical telescopic sections and two horizontal telescopic sections, and the two ends of the vertical telescopic sections and the two ends of the horizontal telescopic sections respectively constitute four telescopic support ends; The drill bit is installed at one end of the horizontal telescopic section, the drive and transmission assembly is located inside the control box, and the power source also includes an electric telescopic rod fixed inside the control box. A servo motor is fixedly connected to the telescopic end of the electric telescopic rod, and the output end of the servo motor is fixedly connected to the rotating shaft. A first mounting plate is rotatably mounted on the control box and connected to the connecting shaft. A second mounting plate is fixedly mounted on the drill bit. The first mounting plate and the second mounting plate are detachably fixedly connected.
[0014] A method for using a segmented environmental monitoring device in mining operations includes the following steps: T1. Adjust the multiple retractable support ends of the mounting assembly to fix the device at the predetermined detection position in the tunnel and align the drill bit with the rock wall to be detected; T2. Start the power source. The power source drives the drill bit to rotate through the rotating shaft, the first power output end, the first gear, the second gear, the first transmission gear and the second transmission gear, the connecting shaft, etc., and the electric telescopic rod pushes the drill bit to feed into the rock wall to perform the drilling action. T3. During the drilling process of the drill bit, a first type of environmental data is collected by a first sensor set at the front end of the drill bit. T4.

T6. Summarize and record the first type of environmental data and the second type of environmental data.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention designs a dual-power output drive and transmission assembly. The same power source synchronously drives the drill bit to rotate for drilling and the spiral conveyor mechanism to rotate for sample delivery. The differential design of gear diameters achieves the differential speed between the drill bit and the spiral conveyor mechanism, ensuring that the spiral conveyor mechanism can rotate at different speeds to complete the rock sample delivery while the drill bit is rotating for drilling. At the same time, the variable torque material accumulation structure of the spiral blades can slow down the movement speed of the rock sample, allowing the second sensor to detect the rock sample more fully and improve the accuracy of the detection data.
[0016] 2. This invention achieves simultaneous sampling and testing of rock samples at different depths and in different sections during rock drilling by setting multiple independent sample detection compartments distributed along the axial direction inside the drill bit, along with independent sampling ports, sampling ports, and second sensors in each compartment. This breaks through the limitation of single-depth detection in existing detection equipment and can obtain differentiated environmental data of the rock mass along the axial direction, providing a more comprehensive and accurate geological environmental basis for mine safety assessment.
[0017] 3. The mounting frame of the present invention adopts a cross-shaped telescopic structure. The device is quickly fixed by abutting the inner wall of the tunnel through four telescopic support ends. No additional fixing base is required. It is suitable for mine tunnels of different sizes and has high installation convenience. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.
[0021] Example 1 like Figures 1-13 As shown, a segmented environmental monitoring device for mining includes a control box 1. The outer surface of the control box 1 is provided with a mounting frame 2 having multiple retractable support ends. The mounting frame 2 abuts against the inner wall of the tunnel through its own multiple retractable support ends. The mounting bracket 2 is configured as a cross-shaped structure, which includes two vertical telescopic sections 21 and two horizontal telescopic sections 22. The two ends of the vertical telescopic sections 21 and the two ends of the horizontal telescopic sections 22 respectively constitute four telescopic support ends. When in use, adjust the telescopic length of the four support ends to make them fit tightly against the inner wall of the mine roadway, thus fixing the device in the roadway. This installation structure does not require additional fixing parts, is suitable for mine roadways with a width of 2-5m, and has strong fixing stability and high installation efficiency. The control box 1 has a hollow interior structure, which is used to install the core components of the drive and transmission assembly. One end of the horizontal telescopic section 22 extends to the outside of the control box 1, providing a support base for the installation of the drill bit 3 and ensuring the coaxiality of the drill bit 3 during the drilling process.
[0022] Example 2 like Figures 1-13 As shown, in this embodiment, the drilling and conveying assembly includes a rotatable drill bit 3, which is installed at one end of the horizontal telescopic section 22. The drill bit 3 is configured as a conical drill body, the diameter of which gradually decreases from near the control box 1 to away from the control box 1, and the taper is 1:5. This structure can reduce the resistance of the drill bit 3 when drilling into the rock and improve drilling efficiency. The drill bit 3 has multiple independent sample detection compartments 4 distributed along its axial direction inside. Each sample detection compartment 4 has a sampling port 5 and a sample outlet 6 that communicate with the outside of the drill bit 3. L-shaped shovels 18 are provided on the side of the drill bit around the sampling port 5 of each sample detection layer 4. The projection of the L-shaped shovels 18 towards the sampling port 5 is larger than the area of the sampling port 5. Specifically, the projected area of the L-shaped shovels 18 towards the sampling port 5 is 1.5 times the area of the sampling port 5. During drilling, the L-shaped shovels 18 can shovel rock debris into the sampling port 5, effectively preventing the sampling port 5 from becoming blocked. Multiple sample detection compartments 4 are separated by at least one annular gasket 20 coaxially arranged with the circular shaft 16. The annular gasket 20 slides with the inner wall of the drill bit 3 to ensure the sealing of the sample detection compartments 4, avoid mixing of rock samples from different segments, and ensure the independence of the detection data. The sampling port 5 is opened through the peripheral side of each sample detection compartment 4 near the smaller diameter side of the drill bit 3; The sample outlet 6 is opened through the peripheral side of each sample detection compartment 4 near the larger diameter side of the drill bit 3; Along the axial direction of the drill bit 3, the outlet 6 on each sample detection compartment 4 is further away from the smaller diameter end of the drill bit 3 relative to the sampling port on the sample detection compartment 4.
[0023] Example 3 like Figures 1-13 As shown, in this embodiment, the spiral conveying mechanism is disposed inside the drill bit 3. The spiral conveying mechanism extends along the axial direction of the drill bit 3 and penetrates multiple sample detection compartments 4. The spiral conveying mechanism slides in cooperation with the inner wall of the sample detection compartment 4. The screw conveyor mechanism includes a round shaft 16 that is detachably connected to the end of the rotating shaft 7, and a screw blade 17 that is fixedly disposed on the circumferential side of the round shaft 16. The round shaft 16 and the end of the rotating shaft 7 are detachably connected by a flange, which facilitates later maintenance and replacement. The spiral blade 17 is located in the inner cavity of the drill bit 3 and is welded to the circumferential side of the round shaft 16. The spiral blade 17 is provided with a material accumulation structure for slowing down the axial movement speed of the material in a local area. The material accumulation structure is set as a variable torque structure of the spiral blade 17. The distance between two adjacent blades of the spiral blade 17 gradually increases from the middle position of the sample detection partition 4 to the sampling port 5 and the sample outlet 6 on both sides. The second sensor includes the material accumulation structure fixedly set on the spiral blade 17. This structure slows down the movement speed of the rock sample in the middle area of the sample detection layer 4. A humidity sensor and a rock sample hardness sensor are fixedly installed on the spiral blade 17 in each sample detection layer 4 as second sensors, and the probe of the second sensor is facing the material accumulation structure. The short-term accumulation of the rock sample in this area can enable the sensor to fully contact the rock sample and improve the accuracy of rock sample index detection. When the spiral conveyor rotates, it transports the rock sample entering through the sampling port 5 to the discharge port 6, realizing continuous collection and transportation of rock samples, and simultaneously completing the synchronous detection of rock samples in each segment.
[0024] Example 4 like Figures 1-13 As shown, in this embodiment, the drive and transmission assembly is located inside the control box 1, including a power source and a rotating shaft 7 connected to the power source. The rotating shaft 7 has a first power output end 8 connected to the drill bit 3 and a second power output end 9 connected to the screw conveyor mechanism. The power source includes a first gear 10, a second gear 11, a first transmission gear 12, and a second transmission gear 13, all of which are located inside the control box 1; The first gear 10 is coaxially fixedly connected to the rotating shaft 7, and the second gear 11 is coaxially sleeved on the outside of the rotating shaft 7, with an annular gap 14 between the inner circumferential surface of the second gear 11 and the circumferential surface of the rotating shaft 7. The first transmission gear 12 is eccentrically set with the rotating shaft 7 and meshes with the first gear 10; the second transmission gear 13 is eccentrically set with the rotating shaft 7 and meshes with the second gear 11; the first transmission gear 12 and the second transmission gear 13 are coaxially fixedly connected. The first power output end 8 includes an eccentrically set connecting shaft 15, which realizes the transmission of the rotational power of the second gear 11 to the drill bit 3. The two ends of the connecting shaft 15 are fixedly connected to the second gear 11 and the drill bit 3 respectively. The rotating shaft 7 is directly connected to the round shaft 16 of the screw conveyor mechanism to form the second power output end 9, realizing the synchronous drive of the drill bit 3 and the screw conveyor mechanism by the same power source. The diameter of the first gear 10 is greater than the diameter of the first transmission gear 12, the diameter of the second transmission gear 13 is greater than the diameter of the first gear 10, and the diameter of the second gear 11 is less than the diameter of the first transmission gear 12. The gear ratio ensures that the rotational speed of the drill bit 3 is higher than that of the screw conveyor mechanism, thus ensuring that there is a speed difference between the two. This allows the screw conveyor mechanism to perform its function of conveying rock samples normally, thereby ensuring that the screw conveyor mechanism can transport samples. The power source also includes an electric telescopic rod 23 fixed inside the control box 1. A servo motor 24 is fixedly connected to the telescopic end of the electric telescopic rod 23, and the output end of the servo motor 24 is fixedly connected to the rotating shaft 7. The electric telescopic rod 23 can drive the servo motor 24 and the rotating shaft 7 to move axially, thereby realizing the feed action of the drill bit 3. The feed stroke can be adjusted according to the detection requirements, and the maximum feed stroke is 1.5m. A first mounting plate 25 is rotatably mounted on the control box 1. The first mounting plate 25 is connected to the connecting shaft 15. A second mounting plate 26 is fixed on the drill bit 3. The first mounting plate 25 and the second mounting plate 26 are detachably fixedly connected by bolts. This connection structure can ensure that the rotational power of the connecting shaft 15 is stably transmitted to the drill bit 3, and facilitates the disassembly and replacement of the drill bit 3, adapting to the testing needs of rock masses with different hardness.
[0025] Example 5 like Figures 1-13 As shown, in this embodiment, the detection assembly includes at least one first sensor disposed at the front end of the drill bit 3 and at least one second sensor disposed in each sample detection compartment 4. The input terminal of the control box 1 is electrically connected to the first sensor and the second sensor respectively, which can collect and transmit detection data in real time. At the same time, a touch screen is provided on the outside of the control box 1, which can directly display the detection data and adjust parameters such as the drilling speed and feed stroke of the device, making operation convenient. The smaller diameter end of the drill bit 3 has a coaxial mounting cavity 19, and the first sensor is set inside the mounting cavity 19.
[0026] A method for using a segmented environmental monitoring device in mining operations includes the following steps: T1. Adjust the multiple telescopic support ends of the installation assembly, adjust the length of the vertical telescopic section 21 and the horizontal telescopic section 22 according to the size of the mine roadway, so that the four support ends are tightly against the inner wall of the roadway, fix the device in the predetermined detection position in the roadway, and align the drill bit 3 with the rock wall to be detected, ensuring the perpendicularity of the drill bit 3 to the rock wall. T2. Start the power source and start the servo motor 24 through the touch screen of the control box 1. The servo motor 24 drives the rotating shaft 7 to rotate. Through the gear transmission structure, the power is transmitted to the drill bit 3 and the spiral conveying mechanism respectively, so that the drill bit 3 rotates and the spiral conveying mechanism rotates synchronously. At the same time, start the electric telescopic rod 23, which pushes the servo motor 24 and the drill bit 3 to feed into the rock wall and perform the drilling action. The feed speed is adjusted to 5cm / min. T3. During the drilling process of drill bit 3, the first sensor (temperature sensor, harmful gas sensor) installed in the installation cavity 19 at the front end of drill bit 3 collects the first type of environmental data such as the temperature and concentration of harmful gases of the rock mass at the front end of drill bit 3 in real time, and transmits the data to the data acquisition module. T4. During the drilling process of drill bit 3, the rotating L-shaped shovel 18 shovels rock debris into the sampling port 5 of each sample detection compartment 4. The power source drives the spiral conveyor mechanism to rotate continuously through the rotating shaft 7, and transports the rock sample that has entered each sample detection compartment 4 from the corresponding sampling port 5 to the corresponding outlet port 6. The rock sample is finally discharged from the outside of drill bit 3 from the outlet port 6. T5. During the process of conveying rock samples by the screw conveyor, the rock samples briefly accumulate at the material accumulation structure in the sample detection compartment 4. The second sensors (humidity sensor and rock sample hardness sensor) set in each sample detection compartment 4 fully contact the rock samples, collect the second type of environmental data such as humidity and hardness of the rock samples in real time, and transmit the data to the data acquisition module. T6. Summarize and record the first type of environmental data and the second type of environmental data, and send the data to the remote monitoring terminal through the wireless transmission module. The touch screen displays the real-time detection data in sync, completing one segmented environmental detection. If it is necessary to continue to detect deeper rock masses, the feed stroke of the electric telescopic rod 23 can be adjusted and the above steps T2-T6 can be repeated.
