摘要

越南下龙煤矿主井井筒掘砌到底后,井筒与巷道4个连接处和装载硐室施工时,以及井筒罐道梁、管道等装备安装时,需要将井筒十字中线向下移设。通过十字中线移设整体稳线测量技术的应用,在井下恶劣环境中,实现了井筒十字中线的高精度快速移设,取得了较好的技术经济效果。
        After the main shaft of Halong Coal Mine in Vietnam was dug and supported to the bottom,the cross middle line of the shaft should be downwardly relocated while 4 joints between the shaft and roadways and the loading chamber were constructed,and the buntons,pipelines and other equipments of the shaft were installed.Through the application of the overall stability line measurement technology for cross line relocation,under severe environmental conditions underground,a high accuracy fast relocation of the cross middle line in the vertical shaft was realized,and the good technical and economical effects were obtained.
