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。
The third mining area of Dayan No.2 mine has been characterized by abnormal water influx at elevation of +530 to +550 m and elevation of +615 m respectively since opening up of transport and return airways in 1992 with a water inflow of 300 m 3 / h. Acid rock salt semi-arid area mine gushing completely different characteristics. This analysis shows that this phenomenon of abnormal water gushing is closely related to recharge of surface water - Hailar river and gushing channel to Quaternary gravel aquifer and fault structure. Based on this, the opinions and measures of prevention and treatment of gushing water in three mining areas are put forward.
