[0002] Currently, mine water tanks are typically inclined shafts. Once filled, the water is drained and then cleared manually, either by excavation or mechanical equipment with human assistance. However, the inclined shafts make it difficult for conventional mechanical equipment to enter, making excavation very difficult. Currently, various technologies are being researched for the comprehensive treatment of coal slurry water in coal mines. However, all existing technologies are single processes that can only partially address the problem and cannot completely resolve the existing problems of coal slurry water in the mines. Human assistance is still required underground.

[0004] In summary, the existing technology not only does not meet the safety requirements of the Security Bureau of "safety with fewer people and safety with no people", but also cannot effectively solve the problem of water tank excavation. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The present disclosure can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0025] To address the safety risks posed by water inrush during mining, underground coal mines typically build two to three water silos to store this water. Some mines use less water, typically 400-600 cubic meters per hour, but others use significantly more, typically 1,500-2,000 cubic meters per hour. Especially during periods of heavy rain, the mines experience significant water inflow, with large amounts of water (averaging 1,800 cubic meters per hour) flushing coarse coal slime into the silos. This flow of coarse particles quickly fills the silos, shortening the excavation cycle to as little as two months, increasing the frequency and urgency of desilting operations. The large amounts of coarse coal slime, including large lumps of coal, that enter the silos with the water flow not only exacerbate the rate of siltation but also make excavation operations extremely difficult, increasing manpower requirements and labor intensity.

[0026] The current method for clearing a water silt is to use a mobile excavator (with a pump) and a filter press to clear the silt after it is full. The silt is then manually stirred, pumped to the filter press for filtration, and then transported by mine cart. However, existing submersible slurry pumps, handling coarse particles, are susceptible to severe wear, frequent failures, and high maintenance costs, which hinder desilting efficiency and economic efficiency. Furthermore, excavation operations require a large number of personnel to work in a dangerous underground environment for extended periods, violating the safety principle of "fewer people means more safety, while no one means less safety" and posing a significant safety hazard. Furthermore, when clearing a water silt, a backup silt must be activated, posing a certain safety hazard. Current manual excavation methods, such as shovels, loaders, scrapers, and chain bucket elevators, are inefficient, labor-intensive, and pose significant environmental risks. Even with existing mechanical excavation methods, manual assistance is required, which is time-consuming and labor-intensive and does not completely solve the water silt clearing problem. This makes it difficult to meet the safety and environmental requirements of modern coal mines. Each excavation takes 30 days and requires a large amount of manpower (630 workers each time). The total annual labor cost is extremely high, and the frequent manual operations further increase the operating costs.

[0027] In summary, in order to solve the above problems, the embodiment of the present invention provides a comprehensive coal slurry water treatment system and water tank in coal mines, which can reduce the frequency of water tank cleaning, shorten the one-time cleaning time, and improve the quality of cleaning. It can also achieve the effect of automatic cleaning and real-time cleaning, and can reduce safety hazards, realize unmanned or less-manned operation, and solve a major technical problem in coal mine scenarios.

[0028] For ease of understanding, first, a comprehensive treatment system for coal slurry water in a coal mine provided by an embodiment of the present invention is described. The comprehensive treatment system for coal slurry water in a coal mine provided by an embodiment of the present invention is arranged at the front end of a preset water tank. In one embodiment, a tunnel can be excavated at the front end of the water tank, and the comprehensive treatment system for coal slurry water in a coal mine provided by an embodiment of the present invention is arranged based on the tunnel, so as to pre-treat the particulate material in the water body, and the water body particles do not enter the water tank, thereby solving the safety hazard problem of entering the tank for treatment. The comprehensive treatment system for coal slurry water in a coal mine provided by an embodiment of the present invention includes a plurality of water treatment branches, and the water treatment branches are arranged side by side along the direction of water flow. The embodiment of the present invention simplifies the treatment process by changing a large amount of water to a small amount of water, so that the treatment capacity of each branch is equivalent to the water consumption of a general mine, which is easier to manage and control. Taking 1,800 cubic meters per hour of water as an example, when there are three water treatment branches, the flow rate of each branch is about 600 cubic meters per hour.

[0029] in, Figure 1 The schematic diagram of the structure of a comprehensive coal slurry treatment system for underground coal mines provided by the embodiment of the utility model is shown as follows: Figure 1As shown, each water treatment branch includes a first material processing system 10 and a second material processing system 20, which are arranged sequentially along the water flow direction. The first material processing system 10 includes dredging equipment 101 for processing coarse particles in the mud. The second material processing system 20 includes a sedimentation tank 201 and a filter press 202 positioned at a predetermined position within the sedimentation tank 201. Figure 1 The multiple water treatment branches are distinguished by water treatment branch a, water treatment branch b, and water treatment branch c. The sedimentation tank 201 is used for sedimentation treatment of the coal slurry water output by the first material treatment system 10, and the filter press 202 is used for filter press treatment of the coal slurry water after sedimentation. In specific implementation, for gushing water with a large amount of coarse particles, the embodiment of the utility model designs a first material treatment system 10 and a second material treatment system 20, including a clearing device 101, a sedimentation tank 201 and a filter press 202, which not only performs sedimentation treatment on the gushing water to gradually settle the suspended matter to the bottom of the tank, but also processes the granular materials of different particle sizes in the water to meet the discharge standards.

[0030] In summary, the embodiment of the present invention provides a comprehensive coal slurry water treatment system for underground coal mines. Through the combination of the first material processing system 10 and the second material processing system 20, it realizes the graded treatment of materials of different particle sizes, thereby improving the treatment efficiency. Moreover, the modern excavation equipment 101 and the filter press 202 have a high level of automation, which reduces manual intervention and improves safety. In addition, the above-mentioned method can effectively treat the particles in the gushing water, realize the entry of clean water into the warehouse, reduce the frequency of the water warehouse being filled, and thus reduce the frequency of excavation. Moreover, it can improve the excavation efficiency, shorten the one-time excavation time, and reduce the impact on production. It can also ensure that the excavation is thorough, avoid residual coal slurry water affecting subsequent production, and improve the quality of excavation. In addition, the embodiment of the present invention does not require manual assistance and can be operated unmanned or with a small number of people on duty. Moreover, it supports remote control to realize the operation of the ground control room above the well, reducing the need for personnel underground and reducing the safety hazards of excavation. It can achieve the effect of automatic cleaning and real-time cleaning, solving a major technical problem in the coal mine scene.

[0031] Furthermore, based on the above-mentioned embodiment, the embodiment of the present invention also provides another comprehensive coal slurry water treatment system in coal mines. The second material processing system 20 further includes a slurry pump 203, which is disposed in the cavity of the sedimentation tank 201; the output end of the slurry pump 203 is connected to the input end of the filter press 202; and the slurry pump 203 is used to transport the coal slurry water material to the filter press 202. For finer materials, the coal slurry water treated by the first material processing system 10 (i.e., the excavation equipment 101) is pumped into the filter chamber of the filter press 202. The filter press 202 applies pressure to the filter chamber, forcing the liquid to be discharged through the filter cloth or filter screen, while the solid particles are trapped on the filter cloth to form a filter cake. Continued application of pressure further dehydrates the coal slurry water to achieve solid-liquid separation. Among them, the second material processing system 20 is equipped with a monitoring system, which is used to monitor the processing process parameters of the coal slurry water, including the flow, pressure and concentration of the coal slurry water; the monitoring system communicates with a preset controller, and the controller is used to control the pumping rate of the mud pump 203 based on the processing process parameters.

[0032] Furthermore, the second material processing system 20 also includes a deep cone thickener, the underflow of which is connected to the input of the slurry pump 203. The deep cone thickener is used to settle the coal slurry water and output a high-concentration underflow of the coal slurry water, which is then transported to the filter press 202 via the slurry pump 203. In a specific implementation, the gushing water enters multiple water treatment branches, which distribute the water volume of the gushing water. The gushing water flows through the cleaning equipment 101, which cleans the coal slurry water (or other gushing water). The cleaned slurry (i.e., fine material) enters the sedimentation tank 201 and is processed by the deep cone thickener. The deep cone thickener's unique structure (cylindrical upper part and conical bottom) allows solid particles to settle to the bottom under the action of gravity, and the clarified liquid is discharged from the upper overflow port. Furthermore, the deep cone thickener is equipped with a dosing device. In one embodiment, the dosing device is located at the input of the deep cone thickener. Among them, flocculants such as PAM (polyacrylamide) and PAC (polyaluminum chloride) are provided in the dosing device. PAM and PAC are added as flocculants while feeding. PAM helps to increase the coagulation effect of the particles, while PAC can improve the stability and sedimentation rate of the flocs. In specific implementation, the above-mentioned controller is also used to control the dosage of the dosing device based on the treatment process parameters of the slurry (i.e., coal slurry water), and improve the solid-liquid separation efficiency through flocculation and sedimentation, thereby obtaining a higher concentration of bottom flow and clearer overflow water. The bottom flow of the concentrator is transported to the filter press 202 for treatment by a pump, so that the clean water can be put into the warehouse.

[0033] In one implementation, the mud pump 203 can be a centrifugal mud pump 203, a piston mud pump 203, a diaphragm mud pump 203, a screw mud pump 203, or a plunger mud pump 203, each of which extracts or transports the mud through a corresponding stirring or extraction mechanism to transfer the mud to the filter press 202. In an embodiment of the present invention, the mud pump 203 is a submersible mud pump 203. Furthermore, in an embodiment of the present invention, a stirring blade can be provided at the input end of the mud pump 203, and the stirring blade is coaxially mounted with the pump motor to simultaneously stir the mud during operation of the pump. The input end of the mud pump 203 is positioned toward the bottom of the sedimentation tank 201, and the output end can be positioned above it. The high-concentration underflow can be pumped to the filter press 202 due to the pump pressure.

[0034] Furthermore, the mud pump 203 can be provided with multiple output ports, one of which is connected to the filter press 202, and the other output ports can serve as flushing ends of the sedimentation tank 201. The opening and closing of each output port is controlled by a controller to achieve different pumping functions of the mud pump 203. Furthermore, the sedimentation tank 201 of the embodiment of the present invention can be a multi-stage sedimentation tank 201 structure, with multiple sedimentation tanks 201 arranged in sequence along the direction of water flow, and the overflow of the current sedimentation tank 201 enters the sedimentation tank 201 behind to treat the gushing water in multiple stages. Furthermore, each water treatment branch can also be provided with multiple second material processing systems 20 side by side along the direction of water flow, that is, in each water treatment branch, the gushing water after the branch is further diverted for treatment. In one embodiment, a single sedimentation tank 201 can be a trough structure with a length of 10 meters and a width of 2 meters, wherein it can be a deep cone sedimentation tank 201. Corresponding to the embodiment of the present invention, each water treatment branch can be provided with two rows side by side along the direction of water flow, with 8 sedimentation tanks 201 provided in each row. It should be noted that the size and number of sedimentation tanks 201 are designed based on the processing capacity, the settling velocity of the suspended matter, the required residence time and the specific process requirements. Figure 2 The schematic diagram of another comprehensive treatment system for coal slurry in underground coal mines provided by the present utility model is shown. Figure 2 In the figure, a top view of the second material processing system 20 of a single water processing branch is mainly shown. Figure 2 The mud pump 203 is arranged in the sedimentation tank 201, and the output end of the mud pump 203 is located at its side end, for connecting with the filter press 202 ( Figure 2 Correspondingly, the position of the deep cone concentrator is set based on the demand. Figure 2 Not shown.

[0035] Furthermore, in order to improve processing capacity, reduce the load of a single machine, and improve reliability, the embodiment of the present invention has multiple cleaning devices 101, and multiple cleaning devices 101 are connected in sequence along the direction of water flow, which can achieve the effect of step-by-step filtration, reduce the risk of clogging of subsequent equipment, and ensure the smooth operation of the entire system. Among them, each cleaning machine is responsible for processing a portion of coarse particles in the mine water, and can focus on processing particles in a specific particle size range, which can improve the overall processing efficiency, and achieve more refined graded processing, and improve the processing effect. Moreover, it can also reduce the load of a single device, extend the service life of the equipment, and reduce maintenance costs. If a certain cleaning machine fails, other cleaning machines can still continue to work, and will not cause the entire system to completely shut down, thereby improving the reliability and stability of the system. Furthermore, the working parameters of each cleaning machine can be flexibly adjusted according to actual needs to meet the needs of different working conditions. Correspondingly, Figure 3 The schematic diagram of the structure of a dredging device 101 provided by the embodiment of the present invention is shown. The figure illustrates the connection structure of multiple dredging devices 101. The number and arrangement order of the dredging devices can be designed according to the actual flow rate of the water body and the composition of the particulate matter. In the embodiment of the present invention, four dredging devices connected in series can be designed, and two are shown in the figure. Figure 2 and Figure 3 The structural layout of a single water treatment branch can be seen.

[0036] Furthermore, each water treatment branch in this embodiment of the present invention is equipped with an inspection robot, which is mounted above the water treatment branch area via an inspection track and is used to inspect the water treatment branch. The inspection robot patrols back and forth, takes photos, generates images, calculates and determines the operating status of each device in the water treatment branch, and can promptly issue an alarm when an abnormality occurs.

[0037] Furthermore, a flow meter is installed in each water treatment branch, and a branch gate valve is installed at the inlet end of the water treatment branch. The flow meter is communicatively connected to a preset PLC control system module; the PLC control system module is used to control the opening of the branch gate valve based on the flow rate detected by the flow meter, and control the water volume so as to evenly distribute the water volume to each water treatment branch for easy processing.

[0038] Furthermore, the first material handling system 10 is also equipped with a monitoring system module. By adding monitoring system modules to key areas of the equipment, the equipment in the first material handling system 10 can be monitored. The monitoring system of the second material handling system 20 is also configured similarly. This allows staff to observe the situation constantly from the control room, promptly address faults, and improve operational efficiency.

[0039] Furthermore, a pressure sensor is provided in each water treatment branch, and the water treatment branch is also equipped with an air supply system; the pressure sensor is communicatively connected to a preset PLC control system module; the PLC control system module is used to control the air supply volume of the air supply system based on the sensing value of the pressure sensor to ventilate the water treatment branch. Among them, the air supply volume can be determined by the computing center system control module to achieve ventilation of the water treatment branch (such as the lane), ensure that the gas meets the standard, and ensure the normal operation of the robot. Furthermore, the embodiment of the utility model is also designed with an intelligent remote maintenance system module, through which the user is promptly guided to perform maintenance, thereby improving the working efficiency of the equipment and reducing energy consumption.

[0040] In summary, in the embodiment of the present invention, a tunnel can be excavated at the front end of the water tank and a multi-branch structure can be set in the tunnel to form multiple water treatment branches. In addition, a horizontal sedimentation tank 201 of 100 meters (such as 150 meters) can be built to achieve the above functions.

[0041] In summary, the other water treatment system provided by the embodiment of the present invention has a simple and practical process, reliable operation, and convenient operation and management. By pre-treating coarse-grained materials, the problem of water tank excavation is solved from the source. Various types of equipment are comprehensively adopted, and the best use conditions and advantages of each equipment can be utilized to give full play to its best functions and effects.
