特殊“S”型覆岩结构冲击地压危险区划分
Risk area division of rock burst hazard in special "S"-shaped overlying multi-strata spatial structure
摘要
Abstract
In order to avoid rock bumps accidents,and ensure the mining safety,two methods were used to study the stress distribution and evolution law of working face 23up03 in different mining process,which includes analysis by overlying multi-strata spatial structure theory and FLAC3D numerical simulation.In addition,the hazard area of rock burst was divided.This paper obtained the conclusion that after 23up02 and 23down07 were mined,when 23up03 working face was pushed to the front and back of the 30m near the 23up02 open-off cut,the rock burst disaster may occurs along the mining face roadway side near goaf.关键词
