摘要
通过采用十字布点法在掘进巷道布置测点记录、分析巷帮与顶底板的位移量、变形速率,对巷道支护方案以及加固措施进行了有效验证。研究表明:12306轨道巷支护优化方案,有效地控制了围岩塑性区向煤体深部的扩展,提高了巷道围岩的稳定性,选用这种优化支护方案是十分合理的。
The displacement and deformation rate of roof and floor plate of roadway are analyzed by using cross distribution point method in the roadway layout record, and the roadway support scheme and reinforcement measures are validated effectively. The research shows that the optimal support scheme of 12306 track roadway can effectively control the extension of surrounding rock plastic zone to deep coal body and improve the stability of roadway surrounding rock. It is very reasonable to select this kind of optimized support scheme.
