Abstract
Shanxi Shouyang Luyang Ruilong Coal Industry Co.,Ltd.150103 track crossheading is located in the middle of the mine field,affected by the 150102 track crossheading and goaf on the south side,it is necessary to determine the reasonable coal pillar width.In view of this situation,this paper analyzes the plastic zone distribution and stress environment of roadway surrounding rock under different coal pillar widths by combining theoretical calculation and numerical simulation,and determines that the optimal coal pillar width is 8 m.The practical production shows that the coal pillar has a good control effect on the deformation of roadway surrounding rock,which provides an empirical reference for the study of coal pillar retention under similar conditions.关键词
