摘 要:煤矿软岩巷道,尤其是高应力软岩回采巷道,由于它们所处的复杂工程地质条件,其支护问题一直是困扰煤矿安全生产的难点问题之一。本文以高应力软岩回采巷道支护为具体工程实例,通过对0910运输顺槽超前注浆及锚网喷联合支护方案,并进行现场工业性试验、矿压观测并评价支护效果。结果表明,锚网喷联合支护较现有的U型钢支护对高应力软岩巷道具有良好的支护效果。Coal mine soft rock roadways, especially high stress soft rock roadway, due to their complicated engineering geological conditions,the supporting problem is always a difficult problem in the production of coal mine safety. In this paper, by the high stress soft rock roadwaysupport for specific engineering example, through the 0910 transport gateway advance grouting and spray anchor net support plan, and siteindustrial test, the mineral pressure observation and evaluation supporting effect. The results show that the combined support of the anchornetwork is better than the existing U shape steel support for high stress soft rock lane.
