Problems solved by technology

[0002] Coal mine floods are one of the five major disasters in mine coal production. The main causes of flood accidents are accidents in the process of coal mine exploration, water discharge, development, tunneling, and coal mining. They are generally divided into aquifer water, surface water, etc. When the influx of various pipelines into the mine exceeds the normal drainage capacity, it will cause mine floods. The frequency of flood accidents increases, and the suddenness is strong and the casualties are large. In order to prevent coal mine floods, the monitoring and early warning of mine water filling , to have timely and quantitative early warning; once a large amount of water gushes suddenly, it is necessary to take emergency rescue measures immediately, quickly determine the nature of the flood, understand the location of the water inrush, the scope of influence, the static water level, the estimated amount of water inrush, the supply water source and the affected ground Afterwards, grasp the scope of the disaster area, find out the distribution of the accident personnel, analyze the places where the trapped persons may hide, so as to organize rescue quickly, and actively take measures such as draining, blocking, and intercepting according to the size of the water inrush and the drainage capacity of the mine; but now The coal mine flood emergency rescue device in the technology only plays the role of blocking. Once the water gushing speed is too fast, it is difficult to ensure the safety of personnel only by blocking
