板集煤矿为缩短主井井筒工程建设周期,在钻井法施工表土段到钻爆法施工基岩段的工序转换过程中,突破传统的单项作业接替延续的施工方式,优化施工方案,合理布局,采取各工序平行交叉作业,即固井(壁后充填)、永久井架的安装、基岩段凿井大临工程等多项工序同时平行交叉作业的施工方式,填补各项工程施工间隙,有效地提高了工序转换效率,实现工序快速转换,为加快建井速度,缩短建井周期节省了宝贵的时间。
In order to shorten the construction period of main shaft and wellbore, in the process of converting process from drilling surface construction to drilling and blasting construction basement, the conventional coal-mining operation is replaced by the continuous construction method, the construction plan is optimized, the layout is reasonable, Take the cross-operation of the various processes parallel, that is cementing (wall filling), the installation of a permanent derrick, the foundation rock shaft drilling a number of processes at the same time parallel cross-operation of construction methods to fill the construction gap effectively Improve the conversion efficiency of the process, to achieve rapid conversion process, saving precious time to speed up the construction of wells and shortening the period of well construction.
