井底车场巷道变形破坏原因分析及防治对策

Reason Analysis on Bottom Roadway Deformation in Pit Bottom and Its Prevention Countermeasures

为了对慧祥煤矿井底车场巷道变形、底鼓进行治理,在分析巷道破坏原因的基础上,提出防治对策,改进了支护方式。研究结果表明,大埋深构造应力区域碎裂膨胀软岩巷道采用"棚、锚、喷、注"联合支护方式支护,技术上可行,经济上合理。

To control the deformation and failure of roadway in Huixiang Coal Mine,the causes of damage were analysed in the paper, relevant countermeasures were also proposed, and the supporting methods were also improved. Research results show that, broken soft rock roadway in regions with large depth and tectonic stress were supported by ＂ shed,anchor,spraying,injection＂ combined supporting mode, the technology is feasible, economic and reasonable.
