Background

The limestone karst area of China is large and wide in distribution, the area is about 2Mkm2, and the limestone karst area accounts for about one fifth of the total area of the whole country. These areas are also important coal producing areas. 60% of coal mines are threatened by karst confined water of the bottom plate in different strengths, and the area and the severity of water damage are the first of all major coal mining countries in the world. In long-term large-scale development, shallow resources are gradually reduced and exhausted, and underground mining depths are also increasing. At present, many mines have entered deep mining, the deepest of which is nearly 1500 m. The pressure of the coal seam floor bearing karst confined water is large, and the water pressure value reaches 2.0-6.5 MPa. In addition, the thickness of a water-resisting layer between a coal bed and an underlying limestone karst aquifer is generally only 10-20 m and can reach 50-60 m at most, the probability of water inrush is greatly increased, and well flooding accidents are increased year by year.

After the gushing water takes place, well water need be taken away, because reasons such as personnel's activity and mechanical work in the well, ground has a large amount of powdered ore in the well, forms the rare mud form after mixing with water, then leads to the pumping efficiency to reduce when mud is thick partially when the extraction at present suction pump, and causes the pump body to damage easily.
