| 摘 要： | 介绍了某岩溶大水铁矿床的水文地质条件及其近矿体帷幕防治水工程的实施情况。通过对钻孔涌水量、注浆量、注浆压力、检查孔效果、地表水位变化及帷幕体下围岩内部位移变化等方面的综合分析,认为该铁矿近矿体注浆帷幕为高堵水率、且围岩稳固的井下近矿体注浆帷幕,解决了矿山因水害困扰无法正常生产的问题,为安全高效开采提供了保障。

| Abstract: | Hydrogeology condition and water prevention project with curtain of a karst inundation iron mine are introduced in this paper.Through comprehensive analysis of drills water inflow,grouting capacity,grouting pressure,effect of inspection holes,surface water level variation and displacement variation in rock under grouting curtain,the grouting curtain of nearly orebody in iron mine is deduced to have high water plugging rate and steady surrounding rock.And the grouting curtain solves the problem of water disaster,and provides security of mining safety and efficiently. |
