Open pit mine inner dump aquifer communication method
The invention discloses an open pit mine inner dump aquifer communication method. The open pit mine inner dump aquifer communication method comprises the work procedures of plugging an original aquifer, building an artificial water-resisting layer, building an artificial aquifer, dredging the aquifer, conducting artificial water replenishing and the like. According to the open pit mine inner dumpaquifer communication method, the original aquifer is plugged with degradable plastics, water resource loss is reduced, and the safety of a pit is guaranteed; construction raw materials of the artificial water-resisting layer come from the mine lot, the construction difficulty is low, cost is low, and the waterproof effect is guaranteed; the aquifer adopts the manner that the middle part bulges, and it is avoided that natural settling of the inner dump causes the aquifer to be compacted, sink and even be blocked; the artificial aquifer is arranged into multiple strips, a water retaining wall is built to reduce the influence of the internal water pressure on the stability of the inner dump, artificial water replenishing according to regions in a later period can be achieved, and water cannot flow into the pit; the artificial water replenishing manner is adopted to accelerate communication between the artificial aquifer and the original aquifer of the inner dump, underground water circulation in the mine lot is guaranteed, pit water can be utilized, and pit water waste is reduced.
本发明公开了一种露天矿内排土场含水层贯通方法，包括封堵原始含水层、再造人工隔水层、再造人工含水层、疏通含水层，人工补水等工序。本发明中，采用可降解塑料对原始含水层进行封堵，减少了水资源的损失，保证了矿坑的安全；人工隔水层构建原料来自矿区，施工难度小，成本低，保证隔水效果；含水层采用中间隆起的形式，避免内排土场自然沉降造成含水层压实下陷甚至堵塞；人工含水层分条设置，建设挡水墙减少内部水压对内排土场稳定性的影响，可实现后期的分区域人工补水且不会让水流入矿坑；采用人工补水方式，加速内排土场人工含水层与原始含水层联通，保证矿区内地下水循环，可对矿坑水进行利用，减少矿坑水浪费。
