摘要
Abstract
This papar is an attempt to investigate the regularity of stress distribution of the coal body at steeply dipping coal seam, by using ANSYS FEM software to simulate the stress characteristics of the coal body at -140 m level wall type working face in north fourth slot of Changgouyu mine. The results show that coal body in front of the working face has the maximum stress concentration factor of 1.92, the working face of lower part is exposed to a higher stress concentration factor, and the maximum stress varying from 4.71 Mpa to 5.12 Mpa occurs between 20 m and 24 m in the lower part of the working face. The study provides theoretical supports for safety production and support design of working face.关键词
