| Abstract: | Based on the analysis of the current supporting situation of roadways whose burial depth are less than 300 meters, 300 to 500 meters and more than 500 meters in Zhengzhou Mining Area. This study classifies the stability of surrounding rock accord- ing to their features, and puts forward relevant supporting methods, which had been put into practice in 28 power substations in the Micun Coal Mine, Zhengzhou Coal Industry Co. , Ltd. The results showed that the deformation of surrounding rock movement has been controlled effectively. |
