摘　　要：以大佛寺煤矿40110综放工作面为研究背景,通过理论分析、数值模拟等方法,研究厚煤层综放工作面矿压显现规律。研究结果表明,回采工作面推进到一定距离时,巷道应力降低,当工作面推进至84 m时,基本顶发生破断。由此推断,40110工作面初次来压步距约在80~90 m之间,周期来压步距为56~64 m。Taking No. 40110 fully mechanized caving face of Dafosi coal mine as the research background, using theoretical analysis and numerical simulation, the law of strata behaviors in fully mechanized caving face with thick coal seam was stud- ied. The results show that the first weighting distance is about 80 - 90 m,and the periodic distance is about 56 - 64 m.
