摘要以王坡煤矿为试验矿井，采用钻孔冲洗液漏失量观测和钻孔彩色电视系统，探测高强度综放开采覆岩破坏高度，并对监测到的裂隙发育演化进行数字化分析和相似模拟试验研究。研究结果表明：王坡煤矿高强度综放开采覆岩破坏高度为94.00～104.92 m；采动岩体裂隙分布的主要特点是裂隙发育以高角度甚至垂直岩层层面为主，裂隙的发育数量与埋深呈现二次方的递增形式，而裂隙宽度与裂隙数量的分布近似呈正态分布；开采过程中裂隙富集区主要集中在前后煤壁，上覆岩层裂隙密度分布曲线呈两端高中间低，形状如“马鞍”型。

Abstract：Taking Wangpo mine as the experimental mining，by borehole flushing fluid leakage and drilling colour television system，the height of overburden failure caving and fissure development evolution are monitoring. And then，the digital analysis and similarity simulation experiment of fissure development evolution are carried out. The research results show as followings：(1) The overburden failure height of high tension fully mechanized caving mining Wangpo mining is from 94.00 m to 104.92 m. (2) The main distribution characteristic of rock fissure is that the evolution of fissure is mainly with the high angle even vertical to the rock strata；the fissure evolution amount is square increasing with the buried depth；and the fissure width is normal distribution approximately with the fissure amount. (3) The fissure cluster region focus on before and after the coal wall；and the fissure density distribution curves of overlying strata are high at both ends，low of the middle，such as saddle-shaped.
