摘　　要：以极不充分开采理论为基础,结合林南仓矿-650水平东二小采区开采实验,研究了间续开采的第1阶段开采的宽度与留设宽度的计算办法,并用概率积分法对该区域一次性全采预计结果与间续开采的实际地表移动变形情况相比较,结果表明,地表建筑物的破坏情况,后者比前者要轻微.应用计算机模拟的方法结合关键层理论对上覆岩层的移动变形特征进行研究,探索间续开采引起地表建筑物破坏较轻的原因.Based on the theory of extremely insufficient mining,we study the calculation method for mining width and pillar width for the first stage of the stepwise mining combining with the practice at-650 m level of the small mining section in Linnancang coal mine.In addition,we compare the prediction result of ＂one-time-fully mining＂ with that of the stepwise mining using the probability integral,showing that the destruction of surface buildings is much smaller than that by prediction.We illustrated the features of movements on the earth＇s surface through the computer simulation firstly and sudied the features of movements and distortion of terrane on the coals based on the key stratum theory to explore why it can decrese the breakage of buildings in different stages.
