Description

technical field [0001] The invention relates to the technical field of auxiliary drainage, in particular to an auxiliary drainage device for preventing and controlling water in coal mine construction and a drainage method thereof. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to dig underground roadways to mine coal, but during the process of digging roadways, there will be continuous There is water influx, which mainly comes from atmospheric precipitation, surface water, aquifer water and fault water. For the needs of coal mining, the water in the roadway needs to be drained. [0003] At present, the water in the roadway is generally discharged through the water pump group. During its use, the water pump group is first transported into the roadway, a...

Problems solved by technology

[0003] At present, the water in the roadway is generally discharged through the water pump group. During its use, the water pump group is first transported into the roadway, and fixedly installed near the place where the water needs to be discharged in the roadway, and then the drainage pipe is laid in the roadway to make the drainage pipe One end of the drain pipe is connected to the water supply end of the water pump group, and the other end of the drainage pipe extends out of the roadway. Finally, a suction pipe is installed at the water pump end of the water pump group, and the suction pipe is immersed in the water of the roadway, and the power supply of the water pump group is connected to realize the roadway. However, the above-mentioned existing technical solutions have the following technical problems: 1. In the course of use, with the continuous excavation of the roadway, it is necessary to continuously extend the suction pipe or move the water pump group to maintain the drainage effect, and the operation is more laborious. Its function is relatively simple, and its practicability is relatively poor, and when there is a landslide in the roadway, it is easy to cause damage to the water pump unit, and the protection effect during operation is poor; However, during the evacuation process of the pumping device after the pumping operation is completed, due to the residual water in the roadway, the roadway is relatively slippery, and the tracked vehicle is prone to slipping when it exits the roadway. Short-term stagnation occurs, while the driving motor that winds the water pipe on the runner keeps rotating at a constant speed, so if the water pipe on the ground does not retain enough length before it exits the roadway, it will cause stagnation near the roadway entrance or even flow back into the roadway; 3. In addition, due to geological structures such as fault rocks, there may be different water accumulation points at different depths in the roadway, especially when the water volume of some water accumulation points is small, it is also necessary to use the water pump to pump the water flow to the ground in a complete and timely manner. Only in the next step can the whole pumping device be moved to the deeper part of the roadway, so the whole pumping operation is slow and the operation efficiency is low
