松软厚煤层掘进巷道过动压区域顶板管理研究

Study on Roof Management of Driving Roadway Passing Dynamic Pressure Area in Soft and Thick Coal Seams

以松软厚煤层掘进巷道过动压区域顶板管理为对象开展研究。结合具体工程实际,在分析掘进巷道原支护的基础上,对留顶煤掘进支护方案的设计做出分析,并对改良后的方案应用效果做出探究。结果表明,改良的支护方案确保了巷道使用的安全稳定。

Roof management of driving roadway passing dynamic pressure area in soft and thick coal seams was studied.Combining with the concrete engineering practice,based on the analysis of the original support of driving roadway,this paper made an analysis of the design of the support scheme for driving with roof coal retained,and explored the application effect of the improved scheme.The results show that the improved support scheme ensures the safety and stability of the roadway.
