The Application of Cable Anchor Support Technology in Soft Thick Mudstone Roadway

The maintenance of soft-rock roadway always troubles the underground geotechnical engineering,and it becomes an important factors of blocking the safety-mining.To further knowing the control mechanism and putting forward control idea of soft roadway,experimental study has been done within a typical soft-rock roadway in a coal mine based on analyzing roadway surrounding rock deformation features and rupturing crack laws of inter surrounding rock by field observation.The control idea of this roadway with high strength cable anchor has been put forward.Though industrial test,the surrounding rock deformation and the development law of inter crack can be effectively controlled by this support technology.The stability of such roadway surrounding rock can be achieved.
