薄煤层复杂地质条件下掘进支护技术研究

Experimental Research on Quickly Tunneling Technique about Thin Seam under Complicated Geological Conditions

宝源集团广得资源有限公司因掘进支护方式落后而影响矿井安全高效生产,需改革支护方式。针对该矿薄煤层复杂地质条件的实际,对锚喷网联合支护方式和支护参数进行了研究应用,检测结果证明采用的支护方式和支护参数满足对巷道稳定控制的需要,效益明显。

It needs reform and impove the laggard supporting mode which have badly affected the high yield and high efficiency in Company of Baoyuan Group Company. Given the thin seam under complicated geological conditions, the research on shotcrete rockbolt mesh combined support way and corresponding parameter has been carried out. The montoring effect shows that the the supporting method and parameter used can satisfy the need for stabilized control in roadway with obvious benefits.
