| Abstract: | Based on the analysis of geology condition, rock mechanics character, and deformation mechanics of surrounding rock of open-off cut in thick-hard coal seam and its transforming technology, the bolt-cable coupling support design was put forward. Based on the practice result, it is feasible on technology, credible on safety, and reasonable on economic by using the bolt-cable coupling support technology. |
