平朔井工开采煤层顶底板水文地质条件评价及防治水对策研究

摘要

针对平朔井工一矿所面临的煤层顶底板水害威胁,在分析矿井采矿、地质等条件的基础上,确定了与煤层顶底板水文地质条件相关的若干因素,分别运用“三图法”和“脆弱性指数法”对该矿煤层顶板涌突水条件和底板突水脆弱性进行了评价,并制定了具体的防治水措施.%Aiming at water hazards menace of Pingshuo No. 1 coal mine roof and floor, the paper ascertains relevant factors of coal mine water bursting on the base of analyzing the mining and geology conditions, and evaluates the roof hydrogeology conditions and floor water bursting vulnerability. At last, it sets down a series of measures of preventing water hazards.
