Abstract
Taking 930 m level water tank submersible drainage electric pump blockage problem in Xiaolongtan Open-pit Mine pit bottom drainage system as the research object,based on the occurrence status of coal seam floor water,surface water runoff,sediment concentration,hydraulic connection,water inrush law and sudden surge situation,combined with hydrogeological data and historical data,through monitoring statistics and scientific calculation comparative analysis,the article clarifies atmospheric rainfall accompanied by sediment convergence is the main factor leading to the formation of silt blockage pumps,discusses and analyzes several treatment measures.关键词
