矿井立井清水排水系统优化设计

Optimal Design of Mine Shaft Clean Water Drainage System

西部地区水文地质条件复杂,一些矿井采取提前疏放顶板砂岩水的措施,增加了涌水量,因而实际排水量往往比预测值要大,矿井排水系统难以满足要求,需要进行改造。矿井立井排水系统改造时,直接利用供水管兼做井下涌水的排水管,不必增加井筒中排水管路和扩建矿井水处理站,即可排出涌水和减少地面矿井水处理量,为立井排水系统改造提供了新的途径。

For the complicated hydrogeological conditions in the western region of China,some mines have taken measures to drain the roof sandstone water in advance for mine safety,the inflow of water is increased,the actual water discharge amount is often more significant than the predicted value.The mine drainage system is difficult to meet the requirements and needs to be modified.In the mine drainage system reconstruction,water supply pipes can be directly utilized as the drainage pipes for discharge the underground water,which can discharge the gushing water without increasing the number of drainage pipes in the shaft and expanding the mine water treatment station,it can discharge the gushing water and reduce the treatment capacity of surface mine water,and a new modification method of the mine drainage system is provided.
