许疃煤矿主要水害水源类型与防治对策

Types and treatment of mine water disasters in Xutuan Coal Mine

许疃煤矿是受水害严重威胁的矿井,自2001年以来,共发生突水事故4次,最大突水量194 m3/h。为了保证矿井的安全生产,必须加强矿井防治水工作。对许疃煤矿主要水害水源类型新生界四含水、第三系"红层"含水层、老空水、灰岩水的富水特点及补给关系进行了系统分析,在此基础上,对老空区突水、断层突水、陷落柱突水等的防治对策进行了探讨。

Xutuan Coal Mine is badly threatened by water disasters. Water-inrush accidents have occurred four times one of which the biggest water-inrush amount is 194 m^3/h since 2001 in Xuntuan Mine. To protect the mine＇s safe produce, water-proof measures must he applied. The water containing characteristics and supplying relations of the main types water disaster sources in cenozoic fourth aquifer, tertiary red bed, old goaf; and limestone in Xutuan Mine are systematically analyzed. On these bases, prevention and control measures to waterinrush in old goaf, fault and collapse column etc are initially discussed.
