Abstract: In terms of the problem of large deformation in soft rock roadway affected by long-term and high mining stress,the deformation mechanism of soft rock and dynamic pressurized roadway was analyzed by means of on-site investigation,surrounding rock stress and deformation monitoring,and numerical simulation,based on a case study located at the belt downhill of Fengshuigou Coal Mine of typical soft rock mines.From the perspective of blocking stress transmission path in deep roof and high-strength support in the shallow part of the roadway,the collaborative control technology for soft rock high-stress roadways was proposed,which consists of dual-active blasting cracks prefabricated in the roof and U-shaped steel support combined with anchor cable high-strength support.Before the belt downhill of 5th coal was not affected by the dynamic pressure of working face,the stress environment of the surrounding rock was optimized, and surrounding rock stability was improved,through the implementation of longshort holes blasting in the deep roof of coal pillar and high-strength anchor cable support in shallow.Based on monitoring methods such as surrounding rock stress,CT of electromagnetic wave,drilling peep,surrounding rock displacement,a comprehensive set of monitoring technology system has been developed to protect the shallow surrounding rock and destroy the deep surrounding rock of the roof of the roadway,ensuring the effect of protecting roadway by the dual-active advance pressure relief.
