| 摘 要： | 济西矿主井由于井口地面下沉,造成凿井井架偏斜变形被拆除,给临时锁口拆除及永久锁口砌筑施工造成困难。通过采用静力爆破技术、安装临时套架及吊盘、挖掘机挖掘及井口布置2台搅拌机拌料等措施,保证了临时锁口拆除及永久锁口安全顺利施工。

| Abstract: | Due to ground subsidence of the main - well, causing deformation and inclination and the sinking headframes are removed, which make difficulties for the temporary locking removement and the permanent lock masonry construction. Through using static blasting technology, installing temporary climbing frame and lifting plate, mining excavators and two blenders mix asphalt guarantee the temporary locking removement and safe and smooth construction of the permanent lock. |
