铲坑煤矿防治水方案探讨

Discussion on Flood Prevention for ChanKeng Coal Mine

永定县铲坑煤矿主要有二号、三号、四号、五号井,属联合改造矿井。该矿三号井2007年发生"10.7"透水事故,导致三号井、四号风井及周边小窑积水,此水患对该矿区二号井、五号井的安全生产造成了严重影响。通过对三个方案进行技术、安全和经济比较,选择较为合理的水害治理方案并提出切合矿井实际的水害治理措施,较好解决了目前该矿区二号井、五号井的水患问题。

The Chankeng Coal Mine in Yongding County is a jointly reconstructed mine,including no.2,no.3,no.4,and no.5 pits.The ＂10.7＂ flooding accident that happened in coal mine 3 in 2007 has led to hydrops of coal mine 3,air shaft 4 and the pits around,which had an extremely bad influence on the safe production of coal mine 2 and 5.By comparing three methods in terms of technology,security and economic effects,a better solution to the problem of flooding is selected,which can better solve the flooding problem on no.2 and no.5 pits.
