摘　　要：为指导高河煤矿W1309高瓦斯超长综采工作面安全高效开采,工作面布置双尾巷回采巷道,有效降低瓦斯浓度,防止瓦斯积聚并采用UDEC、PFC^(2D)数值模拟的方法对超长综采工作面顶板破断特征以及不同放煤步距下顶煤的采出率进行了研究。To guide the safe and effective mining of the W1309 uhra-long fully mechanized gassy coal face in Gaohe Mine, this thesis proposes the double-tail roadways layout to reduce the gas concentration and prevent the gas accumulation. Also, this thesis studies the breaking features of roof in ultra-long fully mechanized coal face and the mining rate of top coal at different coal drawing steps with the method of UDEC and PFC2D numerical simulation.

关 键 词：超长综放工作面 来压步距 采出率
