摘要
Abstract
According to 26071 roadways with the features of deep mining and broken roof,and on the basis of classification of surrounding rock stability,this paper has designed support parameters with coordinate support technology and analyzed the support effect by numerical simulation.Industrial experimentation shows that during phase boring surface displacement,deep displacement and deep force are within reasonable range in roadway,the biggest area reduction is 12.4%,which can meet the requirement.This technology successfully used at 26071 roadways can provide valuable references for other roadways under deep conditions.关键词
