摘要
柳林地区的煤矿巷道围岩存在地质构造复杂、应力大等特点,而且其软岩巷道围岩比较疏松,掘进过程中容易塌陷。对软岩巷道容易破坏的原因进行了分析,结合柳林地区煤矿巷道实际,提出了采用锚网喷、36U型钢棚以及壁后注浆的方式联合支护措施。试验结果显示,此联合支护技术在软岩巷道中实用、高效。
Aiming at the characteristics of complex geological structure and large stress in roadway surrounding rock of LiulinColliery, the paper has analyzed the causes of easy destruction of soft rock roadway and proposed a combined support of wiremesh spray, 36U profile steel canopy and grouting behind segment, which proves to be practical and high efficient in soft rockroadway.
