摘要
华阳五矿局部发育陡倾挠曲、陷落柱发育,在掘进过程中极易出现煤岩层破碎、瓦斯地质异常等现象,对现有的煤巷掘进过构造施工方案进行了优化,采用了全新的施工工艺和支护技术方案,将支护效率提高40%,支护成本降低9.8%。
In Huayang No.5 Coal Mine,steep deflection and collapse columns are developed locally,and coal and rock strata are easily broken and gas geological anomaly occurs in the process of tunneling.The existing construction scheme of coal roadway tunneling structure is optimized,and the new construction technology and support technology scheme are adopted,which improves the support efficiency by 40%and reduces the support cost by 9.8%.
