Description

Technical Field

[0001] This invention relates to a safety auxiliary device for mine exploration, specifically a device and method for separating gas, liquid and solid water in mine exploration. Background Technology

[0002] Coal is the world's most abundant and widely distributed conventional energy source, accounting for 25% of global primary energy consumption. my country's sustained and rapid economic development, particularly the high-speed growth of industries such as power, metallurgy, building materials, and chemicals, has led to a massive and ever-increasing demand for coal.

[0003] In the development of coal resources, exploration and investigation are conducted to ascertain coal reserves and the geological and hydrological conditions of the coalfield. This may involve extending the mining face of existing coalfields to determine the specific spatial location and condition of water bodies in the roof, floor, sides, and front of the mining face, and then carrying out water release operations to prevent water-related accidents. The purpose is to make necessary preparations for effectively controlling mine water. After the conditions are ascertained, safe methods such as drilling are used to release the water; this is known as "water exploration and release" operation.

[0004] During water exploration and release operations, due to the geological and hydrological characteristics of coalfields, the release of water is often accompanied by the simultaneous emission of toxic and harmful gases such as carbon monoxide, hydrogen sulfide, and methane. If this occurs and the concentration exceeds the prescribed limits, power must be cut off and production halted according to safety operating procedures. Water exploration and release operations can only resume after safety measures have been implemented at the work face. The resulting shutdown can last from 10 to 20 days or even longer. Besides the shutdown, if the water exploration is inaccurate and a large amount of high-pressure water is released, causing water damage, it can also lead to equipment damage and significant losses for coal enterprises. Improper handling can also result in casualties, further exacerbating the impact on coal companies.

[0005] Currently, some gas-liquid separation devices have been applied in domestic mines to prevent safety accidents caused by gas leaks. For example, patent CN202348252U, entitled "A Gas and Coal-Water Separation Device," uses a sealed cavity to collect the mixture and discharges gas through an upper connecting pipe and a coal-water mixture through a lower connecting pipe. Patent CN109294652A, entitled "An Automatic Gas-Liquid Separation Device for a Gas Drainage System," uses an inlet, outlet, and outlet to achieve gas-liquid separation and uses negative pressure to discharge gas. While these two separation devices can achieve gas-liquid separation, they cannot handle sudden, large-scale drilling water releases, and their independent installation within the mine causes difficulties in transportation, hindering the efficient and rapid separation and transportation of exploration water. Summary of the Invention

Detailed Implementation

[0020] Example 1: like Figure 1-3 As shown, a mine exploration water collection and discharge device employs a vertical storage tank, including a vertical tank body 101. The side wall of the vertical tank body 101 has an inlet, a manhole, and a pressure transmitter mounting port. The top surface of the vertical tank body 101 has a compressed air inlet, a waste gas outlet, a spray pipe inlet, and a level transmitter mounting port. The bottom surface of the vertical tank body 101 has an outlet and a slag discharge port. An inlet control valve 2 is installed at the inlet, which is connected to the water intake sleeve of the water exploration drill rod. An outlet control valve 3 is installed at the outlet, which is connected to the drainage pipeline of the roadway. A compressed air control valve 4 is installed at the compressed air inlet, which is connected to the compressed air pipeline of the roadway. A waste gas discharge control valve 5 is installed at the waste gas outlet, which is connected to the negative pressure exhaust pipeline of the roadway. A pressure transmitter 7 is installed at the pressure transmitter mounting port, and a level transmitter 7 is installed at the level transmitter mounting port. The level transmitter 6 is equipped with high and low level signals. A water supply control valve 9 is installed at the spray pipe inlet, which is connected to the tunnel water supply pipeline. The spray pipe inlet is connected via a pipeline to a spray head 15 located inside the tank body. The spray head 15 is located at the center of the inner wall of the top surface of the vertical tank 101, with spray heads arranged circumferentially. A slag discharge and cleaning switch 12 is installed at the slag discharge port. In this embodiment, the slag discharge and cleaning switch 12 is a plug structure; other sealed switch structures with solid waste discharge functions can also be used. The bottom of the slag discharge and cleaning switch 12 is connected to the tunnel slag transport vehicle track.

[0021] like Figure 3 As shown, a baffle 13 is provided inside the vertical tank 101, and the baffle 13 is located on the side of the slag discharge port facing the water outlet.

[0022] When the vertical storage tank is in standby mode, the inlet control valve 2, outlet control valve 3, compressed air control valve 4, exhaust gas discharge control valve 5, water supply control valve 9, and pressure relief valve 11 are all in the closed state.

[0023] After the exploration and release operation begins, the water inlet control valve 2 and the exhaust gas discharge control valve 5 are opened. When the exploration and release water containing exhaust gas and slag gushes out, the exploration and release water is introduced into the vertical tank 101 through the water inlet control valve 2 by the water inlet sleeve and pipeline of the exploration drill rod. In the vertical tank 101, the exhaust gas contained in the water is released and, together with the air in the vertical tank 101, is extracted and discharged under the combined action of the continuously shrinking volume and the negative pressure exhaust pipeline. The slag in the water gradually settles to the bottom of the vertical tank 101.

[0024] Water is introduced into tank 1 until the liquid level reaches the high-level signal level of level transmitter 6. Level transmitter 6 then signals, and inlet control valve 2 closes. Subsequently, exhaust control valve 5 closes, outlet control valve 3 opens, and compressed air control valve 4 opens. Water in vertical tank 101 is discharged into the drainage pipeline of the tunnel through outlet control valve 3 by gravity and compressed air pressure. When the water level in vertical tank 101 drops to the low-level signal level of level transmitter 6, level transmitter 6 signals, and outlet control valve 3 and compressed air control valve 4 close. During drainage, the system records the drainage time. The system has a preset lower limit for drainage time. When the drainage time exceeds the preset lower limit, it indicates that the amount of slag deposited in vertical tank 101 is small and does not require cleaning. When the drainage time is less than the preset lower limit, it indicates that the amount of slag deposited in vertical tank 101 is large, occupying a significant portion of the tank's internal volume, and urgent cleaning is required.

[0025] During the water intake and discharge process, the water flows from the inlet to the outlet, and larger slag particles are blocked by the baffle at the discharge port.

[0026] After the water is drained, if the drainage time is less than the preset lower limit, the cleaning operation begins. First, check that the pressure transmitter 7 reading is within a safe range and open the pressure relief valve 11 to further ensure that there is no pressure inside the vertical tank 101. Then, open the slag discharge and cleaning switch 12. Since the baffle is located on the side of the slag discharge port facing the water outlet, most of the sediment is located at the slag discharge port, making it convenient for workers to clean. The cleaned slag falls directly into the slag transport vehicle in the roadway connected to the slag discharge and cleaning switch 12. While cleaning the slag, workers check the sediment and attachments on the inner wall of the vertical tank 101. If there is a lot of sediment and attachments, open the water supply control valve 9, and the spray head 15 sprays circumferentially to clean the inner wall of the vertical tank 101, thereby keeping the inner wall of the vertical tank 101 clean.

[0027] After slag discharge and cleaning are completed, close all ports of vertical tank 101 and wait for the next processing.

[0028] like Figure 9 As shown, the mine exploration drainage gas, liquid and solid separation device of the present invention can use any number of vertical storage tanks, which are arranged in parallel and sequentially along the roadway direction, to facilitate pipeline layout and slag discharge.

[0029] Example 2: like Figure 4 , 5 As shown, a mine exploration water collection and discharge device employs a horizontal storage tank, including a horizontal tank body 201. Inlet and outlet are respectively installed on the lower sides of the horizontal tank body 201. An inlet control valve 2 is installed at the inlet, which is connected to the water intake sleeve of the exploration drill rod. An outlet control valve 3 is installed at the outlet, which is connected to the drainage pipeline of the roadway. A compressed air inlet and an exhaust gas outlet are provided at the top of the horizontal tank body 201. A compressed air control valve 4 is installed at the compressed air inlet, which is connected to the compressed air pipeline of the roadway. An exhaust gas discharge control valve 5 is installed at the exhaust gas outlet, which is connected to the negative pressure exhaust pipeline of the roadway. The horizontal tank body 201 is also equipped with a level transmitter 6 and a pressure transmitter 7. The level transmitter 6 is equipped with high and low level signals. A spray pipe 14 is horizontally installed along the axis inside the tank body 1. The spray pipe 14 penetrates the horizontal tank body 201. Spray nozzles are installed on the pipe wall inside the horizontal tank body 201. The two ends of the spray pipe 14 are the drive side and the water supply side, respectively. The spray pipe 14 is sealed to the two end walls of the horizontal tank body 201 through bearings. The drive side on the left is connected to the rotary drive motor 8, and the water supply side on the right is connected to the rotary joint 10. The spray pipe 14 and the water supply control valve 9 are connected to the two sides of the rotary joint 10, respectively. The water supply control valve 9 is connected to the tunnel water supply pipeline. To further reduce costs, or to design a separation device specifically for handling large-scale exploration water outflows, multiple tanks with spray pipes connected in series can be used. In this structure, the tanks containing the series spray pipes are horizontally coaxial. One end of the series pipeline is a rotary drive motor 8, and the other end is a water supply control valve 9. Each tank's spray pipe has a rotary joint between it and the water supply control valve 9. A pressure relief port is located on the upper right side wall of tank 1, and a pressure relief valve 11 is installed thereon. The inlet control valve 2, outlet control valve 3, compressed air control valve 4, exhaust gas discharge control valve 5, water supply control valve 9, and pressure relief valve 11 are all valves with on / off functions. The bottom of the horizontal tank 201 is provided with a slag discharge port, and the slag discharge port is equipped with a sludge removal switch 12. In this embodiment, the sludge removal switch 12 is a plug structure, but other sealed switch structures with the function of discharging solid waste slag can also be used. The bottom of the sludge removal switch 12 is a roadway slag transport vehicle track. A baffle 13 is provided on the inner wall of the horizontal tank 201 on the side of the slag discharge port facing the water outlet. In this embodiment, there are two slag discharge ports, arranged from the water inlet to the water outlet. The gap between the baffle at the slag discharge port near the water inlet and the bottom of the inner wall of the tank 1 is larger than the gap between the baffle at the slag discharge port near the water outlet and the bottom of the inner wall of the tank 1. Further, if such a baffle 13 is used... Figure 3-5In the baffle structure, the size of the hole or gap of the baffle at the slag discharge port on the side closer to the inlet is larger than the size of the hole or gap of the baffle at the slag discharge port on the side closer to the outlet.

[0030] When the horizontal storage tank is in standby mode, the inlet control valve 2, outlet control valve 3, compressed air control valve 4, exhaust gas discharge control valve 5, water supply control valve 9, and pressure relief valve 11 are all in the closed state.

[0031] After the exploration and release operation begins, the water inlet control valve 2 and the exhaust gas discharge control valve 5 are opened. When the exploration and release water containing exhaust gas and slag gushes out, the exploration and release water is introduced into the horizontal tank 201 through the water inlet control valve 2 by the water inlet sleeve and pipeline of the exploration drill rod. In the horizontal tank 201, the exhaust gas contained in the water is released and, together with the air in the horizontal tank 201, is extracted and discharged under the combined action of the continuously shrinking volume and the negative pressure exhaust pipeline. The slag in the water gradually settles to the bottom of the horizontal tank 201.

[0032] Water is introduced into the horizontal tank 201 until the liquid level reaches the high-level signal level of the level transmitter 6. The level transmitter 6 then signals, and the inlet control valve 2 closes. Subsequently, the exhaust control valve 5 closes, the outlet control valve 3 opens, and the compressed air control valve 4 opens. Water in the horizontal tank 201 is discharged into the drainage pipeline of the tunnel through the outlet control valve 3 by gravity and compressed air pressure. When the water level in the horizontal tank 201 drops to the low-level signal level of the level transmitter 6, the level transmitter 6 signals, and the outlet control valve 3 and compressed air control valve 4 close. During the drainage process, the system records the drainage time. The system has a preset lower limit for the drainage time. When the drainage time is greater than the preset lower limit, it indicates that the amount of slag deposited in the horizontal tank 201 is small and does not require cleaning. When the drainage time is less than the preset lower limit, it indicates that the amount of slag deposited in the horizontal tank 201 is large, occupying a significant portion of the tank's volume, and urgently needs cleaning.

[0033] During the water inlet and outlet processes, the water flows from the inlet to the outlet. Larger slag particles are blocked at the corresponding slag discharge port by a baffle plate that is close to the inlet and has a large gap between it and the bottom of the inner wall of tank 1, with large holes / slits. Smaller slag particles are blocked at the corresponding slag discharge port by a baffle plate that is close to the outlet and has a small gap between it and the bottom of the inner wall of tank 1, with small holes / slits.

[0034] After the water is drained, if the drainage time is less than the preset lower limit, the cleaning operation begins. First, check that the pressure transmitter 7 reading is within a safe range and open the pressure relief valve 11 to ensure that there is no pressure inside the tank 1. Then, open the slag discharge and cleaning switch 12. Since the baffle is located on the side of the slag discharge port facing the water outlet, most of the sediment is located at the slag discharge port, making it convenient for workers to clean. The cleaned slag falls directly into the slag transport vehicle in the tunnel connected to the slag discharge and cleaning switch 12. While cleaning the slag, the workers check the condition of the sediment and attachments on the inner wall of the tank 1. If there is a lot of sediment and attachments, open the water supply control valve 9, start the rotary drive motor 8, and spray water from the nozzles on the spray pipe 14. At the same time, the spray pipe rotates continuously to clean the inner wall of the tank 1, thereby keeping the inner wall of the tank 1 clean.

[0035] After slag discharge and cleaning are completed, close all openings of tank 1 and wait for the next processing.

[0036] In this embodiment, the spray pipe 14 and the two side walls of the tank 1 Figure 4 , 5 In addition to the bearing connection shown, the following method can also be used: the spray pipe 14 is connected to the drive side end wall of the tank 1 by a bearing seal, and is connected to the water supply side end wall by a rotary joint. That is, the rotary joint is installed on the water supply side end wall of the tank 1, the rotating part is connected to the spray pipe 14 facing the inside of the tank, and the fixed part is connected to the water supply control valve 9 facing the outside of the tank. Using this method can further reduce the manufacturing cost.

[0037] like Figure 10 As shown in the present embodiment, any number of horizontal storage tanks can be used, and the horizontal storage tanks are connected in parallel and arranged sequentially along the roadway direction to facilitate pipeline layout and slag discharge.

[0038] In embodiments one and two, there is a gap between the baffle 13 and the bottom of the inner wall of the vertical / horizontal tank to facilitate water flow. The baffle can also be provided with holes, slits, mesh structures, or other forms that facilitate water flow, such as... Figure 6-8 As shown.

[0039] It should be noted that in embodiments one and two, the number of slag discharge ports and baffles can be one or more. When there are multiple baffles, it is sufficient to ensure that the distance between the baffle near the water inlet and the bottom of the inner wall of tank 1 is greater than the distance between the baffle near the water outlet and the bottom of the inner wall of tank 1. Figure 6-8 In the partition structure, it should be ensured that the size of the hole or gap of the partition near the slag discharge port on the side closer to the water inlet is larger than the size of the hole or gap of the partition near the slag discharge port on the side closer to the water outlet.
