摘要
同一巷道单一支护形式具有一定的局限性,无法有效实现巷道整体区域的稳定控制。本文以正益煤矿围岩条件复杂的11-104回风顺槽为工程背景,提出11-104回风顺槽分区域差异性联合支护技术,在正常区域采用锚网索联合支护技术,在围岩破碎区域采用锚网索注联合支护技术。该技术应用后,实现了11-104回风顺槽围岩的稳定控制。
In view of the limitation of single support form in the same roadway which cannot effectively realize the stability control of the overall area of the roadway,the author proposes the regional differential combined support technology at 11-104 return air-return crossheading with complicated surrounding rock conditions in Zhengyi Colliery,in which the combined bolt-mesh-anchor support is applied in the normal area while the combined support technology with bolt-mesh-anchor grouting in the broken area of surrounding rock,realizing the stability control of surrounding rock.
