Effect of support and surrounding rock is one of the key factors of high once mining full height mining technology efficiency of mine. The 8101 large mining height working face as the engineering background,analysis,numerical calculation and simulation and oth-er means of integrating the theory,it studied the interaction mechanism of support and surrounding rock in Wangzhuang Coal Mine. The thick seam mining all high support and surrounding rock interaction,the method to calculate the working resistance can meet the re-quired support safe and efficient production of coal wall;analyzes the characteristics and spalling mechanism,large mining height work-ing face coal wall spalling failure forms of the crack is presented,it made the reinforcement technology of coal wall grouting correspond-ing. Related research results in the field practice,this method the broken roof,control of the coal wall damage,ensure the safety in work-ing face rapid development,and achieved very good results.
