摘要
宜章金华山煤矿是地质构造复杂矿井,围岩属软岩,通过对±0m永久水仓及车场进行锚网喷注联合支护实际应用,证实锚网喷注联合支护可靠、效益明显,在小型矿井软围岩巷道中推行是可行的。
Aiming at the complicated geological structure of Yizhang Jinhuashan Colliery with soft surrounding rock, anchor--mesh shotcreting support is first implemented in ±0 m water sump and yard, which has been proved reliable, effective and feasible in roadway with soft surrounding rock of small collieries.
