大倾角煤层巷道支护的改进研究与实践

Improved Study and Practice of Support for Seam Roadway with Large Dip Angle

掘进和支护大倾角煤巷时存在高帮打眼、架棚和维修都较困难的问题。通过对巷道支护相关情况的数值模拟和理论分析,并以数值模拟和理论分析的结果为依据,设计适合大倾角巷道支护状况的支架,能取得较好的支护效果。

Several difficult problems such as high flank hole drilling and support setting and maintenance exist while driving and supporting coal roadway with large dip angle. Through numerical simulation and theoretical analysis on roadway support and by taking the results of the numerical simulation and theoretical analysis as the basis, a support suitable for roadway support with large dip angle was designed, and better support effect can be obtained.
