摘要
钻井水溶采矿是利用钻井连通地表和地下矿体,通过水的流通将地下矿床中的有用组分溶解,再通过人为施加的压力把地下饱和含矿溶液压出地表,进行有用组分提取的一种采矿方法。该采矿方法优势明显,可开采埋藏较深的可溶性矿床,具有投资少、见效快、设备和工艺简单、生产费用和能耗低、对环境污染小等优点;此方法同时也存在回采率较低、不易控制溶蚀范围、当开采埋藏浅的矿床易引起地表塌陷等问题。
In the drilling well water dissolution mining, the underground orebody is connected with surface drilling well is by the drilling well. The useful component of deposit is dissolved by the water flow, and then the underground saturated solution is pressed onto the surface by the artificial pressure in order to abstract the useful component. The superiority of this mining method is clear, which can be used in the mining of deep soluble deposit, with low cost, rapid effect, equipment and technique simple, low energy expense and environment pollution light. Nevertheless, the shortages of this method are recovery low, dissolution range control not easy, surface collapse resulted easily as the mining of shallow ore deposit, etc.
