In view of the large, non-uniform deformation and serious damage of the support system of the perimeter rocks of the deep acute inclined crushing roadway, the 31201 transportation roadway of Linyi Mining Group was used as the engineering background to analyze the causes of roadway deformation and destruction through field research, theoretical analysis and field experiments. The research results showed that the top plate coal rock body strength was low, the level of stress was high, with asymmetric distribution, the key parts were easy to destroy, the top plate water was for the roadway deformation of the main reasons for the destruction, based on the above study "high strength anchor net cable spray" + "abnormal broken section grouting reinforcement "the joint support scheme was proposed. Engineering practice showed that the scheme can effectively control the deformation and damage of the deep sharply inclined crushing roadway and provide technical support for the control of roadway perimeter rock under similar geological conditions.
