摘　　要：以小龙潭露天矿坑底排水系统930 m水平水仓潜水排水电泵闷泵问题为研究对象,基于煤层底板水的赋存状态、地表水径流、泥沙汇流、水力联系、涌水规律、突涌性情况,结合水文地质资料和历史数据,通过监测统计和科学计算对比分析,明确了大气降雨伴随泥沙汇流是导致淤泥闷泵形成的主要因素,同时探讨分析了几种治理措施。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.
