Abstract
Aiming at the problem of large deformation and difficult maintenance of deep roadway under the influence of high geo-stress and strong dynamic pressure,taking the surrounding rock control of 1105 roadway in Hudi Coal Industry as an ex-ample,the deformation characteristics of deep soft rock roadway and the control countermeasures of surrounding rock are an-alyzed and discussed by means of geological data analysis,surrounding rock morphology observation,borehole peeping of surrounding rock fracture and field test.The results show that the deep high geo-stress,syncline tectonic stress,advanced mining stress,roadway crossing layer and surrounding rock fracture development are the main causes of roadway deforma-tion.Based on the deformation characteristics and mechanism of 1105 roadway,the active and passive combined support countermeasures of grouting concrete-filled steel tube+high-strength anchor mesh cable spray support'for strong dynamic pressure roadway are proposed,which can provide reference for surrounding rock control of deep roadway under similar con-ditions.关键词
