北阳庄矿二采区出水后开采方案设计

Mining plan design after water in No. 2 mining area of Beiyangzhuang Mine

基于北阳庄矿二采区东翼运输巷严重突水影响二采区正常生产的情况,结合该矿出水后水文地质条件和现有的井巷工程,对两个方案的技术及经济进行比较,提出适合该矿二采区出水后的开采方案。通过对方案的设计调整,最大程度降低了出水对工程带来的影响,达到矿井安全开采条件。

Based on the serious water affecting No. 2 mining area production in the east wing transportation roadway in Beiyangzhuang Mine, combined with hydrogeologieal conditions and roadway engineering, the two plan was compared, the mining plan after water was given, whieh reduced the negative effect to the maximum, achieving the mining condition.
