摘　　要：针对大采高综放工作面过走向断层存在的割矸量大、工作面推进速度慢等问题,在研究顶底板强度及稳定性的前提下,利用几何模型论证的方法求得不同起坡位置和角度对留煤量和破岩量的影响,提出了改变过断层起坡位置和起坡角度的开采方法。优化后,破岩量和煤炭采出率都有了很大的提高,对相似情况的过断层具有一定的指导作用。In view of the problems such as large amount of gangue cutting and slow advancing speed of the working face passing through the strike fault in the fully mechanized caving face with large mining height,on the premise of studying the strength and stability of the roof and floor,this paper obtained the influence of different slope starting positions and angles on the coal reserve and rock breaking amount by using the method of geometric model demonstration,and put forward the mining method of changing the slope position and angle of the fault.After optimization,the amount of rock breaking and coal recovery rate has been greatly improved,which has a certain guiding effect on the fault passing method under similar conditions.

关 键 词：走向断层 起坡位置 起坡角度
