摘　　要：由五沟煤矿大量的钻探资料及现场试验数据,分析了含水层下大采高缩小防护煤柱综采工作面的工程地质特征。根据相关规程及相似模拟实验对综采工作面开采后导水裂缝带、冒落带高度的计算分析,得出五沟煤矿1012综采面缩小防水煤柱开采在技术上是可行的。The engineering geological characteristics of a fully mechanized mining face whose waterproof coal pillar is reduced under the water-bearing layer are analyzed by a lot of information of drilling and field test data of the Wugou mine.According to correlative regulations and similar simulation experiment,the calculation and analysis about the height of water conducting fractured zone and roof falling zone are carried out for the fully mechanized mining face.The results indicate that the fully mechanized mining face of 1012 in Wugou colliery to reduce waterproof coal pillar for mining is feasible in respect of technology.
