Research on surrounding rock deformation features and coordination support technology of high stress gateway
Abstract：Based on the investigation of the engineering geology condition of Shibangou coalmine, the factors that cause the deformation in the tailgate of No. 18002 working face were analyzed by utilizing FLAC software. Then controlling ways of high pre-stress strength bolts and anchor coordination supports were proposed. Research results indicate that the reasons for large deformations are complex. Industrial test results show that the supporting technique could successfully control the deformation under high pressure and create better conditions for mine safety production.
