摘　　要：针对矿山排水系统改扩建项目普遍存在的难点,结合国内某金属矿山工程现状,对该矿目前已有的Ⅱ矿区主排水系统进行分析,认为存在排水能力与排水需求不匹配的问题。分别对Ⅰ矿区新建排水系统的排水管网设计及Ⅱ矿区排水系统的改造方案进行了详细计算分析和分析。针对Ⅰ矿区新建排水系统输送距离长、路径复杂,易受到停泵水锤的冲击,设置了消除水锤的防护缓冲系统。分析认为,该水锤防护系统可以有效保护泵房内的设备设施。For the difficulties commonly existed in the water drainage upgrading of the expansion mine project,and based on the current situation of a metal mine project in China,this article analyzes the existing main drainage system of mine area II and considers that there is a mismatch between the drainage capacity and the drainage demand.This article provides a detailed analysis and calculation on the drainage network design of the new drainage system in mine area I and the renovation plan of the drainage system in mine area II respectively.The new drainage system in mine area I has a long conveying distance and a particularly complex path,which is very susceptible to the impact of water hammer caused by pump stoppage,so a protective buffer system is set to eliminate water hammer,and hydraulic calculation and implementation effect of the drainage pipe network were analyzed.The analysis shows that the water hammer protection system can effectively protect the equipment and facilities in the pump room.
