摘要
福城煤矿副井井筒延伸掘进时采用FJD-6A型伞钻凿岩、光面爆破破岩、HZ-6型抓岩机出矸、MJY3.7/7.5型移动式金属大模板砌壁,实现了副井筒快速、安全掘进。现场应用后,井筒延伸速度达到90 m/月,同时井壁围岩稳定,现场取得显著应用效果。
FJD-6A umbrella rock drilling,smooth blasting rock,HZ-6 clamshell,MJY3.7/7.5 mobile metal large formwork wall have been used in the extended excavation of the auxiliary shaft of Fucheng Colliery,which achieves rapid and safe drilling of auxiliary shaft,with 90 m/month of the shaft extension speed.
