高预应力锚索支护优化方案探讨

Discussion on Optimization Scheme of High Prestress Cable Supporting

通过科学分析地质条件和巷道破坏机理,采用高预应力锚索支护优化方案,解决了煤巷掘进期间的煤质松软、巷道变形大、多次维修及施工成本高等难题,为巷道安全快速掘进提供了条件,也创造了较好的经济效益。

Through scientific analysis of geological condition and roadway damage Mechanism and adaptation of the optimized scheme of high pre-stress cable supporting, the paper solved a series of problems during the heading excavation process, such as soft coal seam, roadway with large deformation, high maintenance and construction cost. Also, the paper provided conditions for safe and quick excavation of roadway, and made great economic benefits.
