冬瓜山铜矿千米竖井工作面突水淹井及其治理

Water Irruption Flooding on Working Face of 1000m Deep Shaft and Its Control in Dongguashan Copper Mine

竖井千米深处工作面突水淹井，国内没有先例，国际罕见。本文密切结合工程实际，从深井工作面突水原因分析入手，沿袭以往浅井、中深井治水的经验，采用工程类比法确定抛石注浆及工作面预注浆的施工方案。施工中利用水力平衡原理，使治理工程一次成功，堵水率达９８％，总体性能达国际领先水平。

The water irruption flooding on the working face of 1000m deep shaft was not found in China,also was rare in the world.In close combination with the engineering reality,from the beginning of analyzing the causes of water irruption on the working face of deep shaft,by experiences in controlling the flooding of shallow and deeper shafts in the past,the plan on an engineering analogy method determining the throwing grout and the face pregrouting was adopted.The principle of hydraulic equilibrium was used in the construction to make the water controlling works meet with once success.The water intercepting rate was up to 98%,and the total performance of this works was in a position of international leading level.
