滇西红牛铜矿矿坑涌水量变化原因分析

Cause Analysis on Water Inflow Change of Mine Pit of Hongniu Copper Mine in Western Yunnan

香格里拉市红牛铜矿在生产过程中,矿区地下水涌水量远大于设计排水量,造成设计排水方案不能满足矿山正常生产的排水需求。系统分析了造成矿坑涌水量变化的原因,采用水文地质比拟法进行了矿坑涌水量预测,3822 m中段旱季平均排水量28481 m^(3)/d,雨季平均涌水量42957 m^(3)/d,最大涌水量63054 m^(3)/d,为矿山排水方案变更提供可靠依据。

In the production process of Hongniu copper mine of Shangri-La,the underground water inflow of mine is much large than the designed water discharge capacity,therefore,the designed water discharge scheme can not meet the water discharge requirements of normal production of mine.The reason for water inflow change of mine pit was analyzed systematically,the hydrogeology analogue method was adopted to predicated the water inflow of mine pit,the average water discharge capacity of 3822 m middle section in dry season is 28481 m^(3)/d,the average water inflow capacity in rain season is 42957 m^(3)/d,the maximum water inflow capacity is 63054 m^(3)/d,it supplies reliable reference to water discharge scheme changing of mine.
