摘　　要：上行开采在赵家梁矿应用是否可行,通过物理材料相似模拟实验及计算机进行数值模拟,结合理论分析,得到5-2煤层采后覆岩运动规律及"三带"特征,冒落带高度18m,为采高6倍,裂隙带高度49m,为采高16.3倍,4-2上煤层及其顶、底板岩层裂隙最大10cm,8cm,7cm.裂隙在下沉带盆底闭合得出可实现上行开采的结论。The feasibility for the application of the ascending mining method in Zhaojialiang coal mine is elaborated. According to resemble simulation experiments, computer experiments and theory analysis, the basic law of overlayer strata movement and ＂three-band＂ characteristics of rock movements in working face are studied after mining of 5^-2 coal seam, and the influence of 4^-2上 coal seam is analysed. Experiments show that ascending mining can be achieved.
