摘要
Abstract
By using FLAC3D software, deformation failure regularity of surrounding rock in mining roadway with easy caving roof under different length and diameter of bolt was simulated , the stress distribution of mining face , deformation distribu-tion laws and bolt reasonable supporting parameters of mining roadway systematically analyzed .The research results show that advanced abutment pressure is about 30m which needs advanced supporting , the reasonable bolt supporting parameters are that the bolt length is 1.8m and the bolt diameter is 18mm.关键词
