安庆铜矿水文地质特征及矿坑水害防治

Hydrogeological Features and Control of Pit Floodin Anqing Copper Mine

介绍了安庆铜矿的水文地质特征,指出随着向深部开采,造成地面塌陷和地表水下灌,致使矿坑最大涌水量出现不断增大的趋势。针对这一情况,对井下出水点进行封堵及地表综合治理,使最大涌水量的增势得以控制,从而得出上堵下排、避免矿井带压开采的防治措施。

The Paper introduces the hydrogeological features of Anqing Copper Mine and points out land subsidence and surface water pouring downwards caused by the deepening mining may result in the increasing trend of the maximum outflow rate within the pit.After plugging the downhole outflow points and comprehensive treatment of the surface,the increasing trend of the maximum outflow rate was controlled.The measures of plugging in the upper and discharging downwards,avoiding mining with pressure are obtained for the control of pit flood.
