| Abstract: | The severe subsiding area had happened in the 255main transport roadway of Linglong Gold Mine, which damaged secure production. The geology of subsiding area is complicated with many unknown cases. The grouting and bolting technique is designed based on analysis of surrounding rock in roadway and actual conditions in spot. The design laws and cruxes of the grouting and bolting are described. The design methods of it are presented, including grouting holes radius and location , material ratio and length of reinforcement bars and holes, inter-relations of them are included too. |
