摘要 在3107煤巷掘进期间,施工围岩窥视钻孔,观察巷道围岩应力破碎情况,进行合理有效的锚杆支护设计,进一步提高煤巷围岩稳定性,有效防止了掘进期间巷道围岩出现破碎、变形,保证了巷道安全快速掘进。 During the excavation of 3107 coal roadway,the construction surrounding rock peeps at the boreholes,observes the stress fracture of the surrounding rock of the roadway,carries out reasonable and effective bolt support design,further improves the stability of the surrounding rock of the coal roadway,effectively prevents the breakage and deformation of the surrounding rock during the excavation,and ensures the safe and rapid excavation of the roadway.
