钱家营矿充填开采可行性分析及设计

Feasibility analysis and design of Qianjiaying Mine filling mining

通过对钱家营矿资源赋存现状的分析,采用固体充填开采技术解决"三下"压煤问题,充填开采时先建设矸石不升井系统、后建设地面矸石充填系统,优化了矿井生产系统,减少了固体废弃物排放,降低了固体废弃物排放费用,提高了煤炭采出率,获得了较好的经济效益和社会效益。

Through analysis of Qianjiaying Mine resources hosting status by solid filling mining technology to solve the mining problem of mining under village, water body and bridge, when filling mining, waste rock without rising shaft system was set up, then the ground waste rock filling system, the mine production system was optimized, reduced the solid waste emissions and the costs of solid waste discharge, improved the coal recovery rate, obtained better economic benefits and social benefits.
