断层破碎带软岩巷道支护技术
Support technology of soft rock roadway in fault fracture zone
摘要
Abstract
In order to offer valid technical support for the research of the supporting technology for the soft rock roadway through the fault broken zone,this paper adopted theoretical analysis,three axis compression test of rock,the surface of surrounding rock deformation monitoring and MIDAS / GTS numerical simulation,and analyzed the fault broken zone on the deformation of surrounding rock of roadway.Taking the fault broken zone at 1088 m location of 3-1 coal auxiliary transport roadway in Hong Qing Liang coal mine as engineering background,this study proposed a combined supporting method by changing the original rectangular section to the straight wall arch section,cable anchor and U type steel support.The research results show that choosing a fault core area of the one observation sections in surrounding rock,the surface deformation observation and numerical simulation results were compared and analyzed.The results of numerical simulation and site actual monitoring data are basically consistent.The construction to the fault broken zone 20m range with reinforcement of surrounding rock by grouting to ensure safe through the fault broken zone.关键词
