应城石膏矿四分矿井巷开拓工程,有主井、副井、风井三条竖井及中段平巷、上山等,是矿井延续生产的关键工程,要求尽早建成投产。为加快工程进度,我们对主井井架采用平卧组装、整体提升、空中旋转吊装新工艺,在有限的场地内,用较短的时间和较简单的机具,将主井施工井架一次吊装成功,实现了施工井架组装与井筒锁口掘砌平行作业。 Yingcheng gypsum mine quarter mine road development project, there are the main shaft, vice shaft, shaft shaft and the middle lane, up the mountain, is a key continuation of the mine production, requiring completion and put into operation as soon as possible. In order to speed up the progress of the project, we adopted the new technology of supertalling, lifting and hanging in the air of the main shaft derrick. In a limited space, the derrick of the main shaft was hoisted successfully in a short time and with relatively simple machinery. Achieved the construction of derrick assembly and wellhead lock dig parallel work.
