内蒙古大雁二矿三采区涌水灾害分析与治理

Analysis and Prevention for Hazard of Water Inrush of Panel No 3 in Mine No 2 Dayan

大雁二矿三采区自１９９２ 年开拓运输和回风巷道以来， 分别在＋ ５３０～＋ ５５０ ｍ 和＋ ６１５ ｍ 标高出现涌水异常， 涌水量达３００ ｍ ３／ｈ， 表现出与我国北方非碳酸盐岩半干旱地区矿井涌水完全不同的特征。本文分析研究认为， 这种异常涌水现象与补给水源为地表水—海拉尔河和涌水通道为第四系砂砾含水层及断裂构造密切相关。据此提出了三采区涌水的防治意见与措施。

There emerged unusual mine inflow at +530～550 m and +650 m in the panel No.3 in the mine No.2 Dayan.Since the panel's transport tunnel and air return way have tunneled in 1992, the amount of inflow reaches 300 m 3/h, showed different character to non carbonate and semi dry area in North China. After studied and analyzed, regard the unusual inflow has intimate relations with water provision resource Hailaer River and path the Quaternary loose sand and pebble water bearing stratum and fault structures. Thus, presents the preventive advice and measure.
