为保证建井顺利通过含水量较大的冲积层段,通常采用冻结法。北阳庄矿井风井井筒冻结采用单圈插花布置冻结孔、低温大流量快速冻结方案,并采用可视监测、监控信息化施工技术,创造了蔚州矿区第一个优质冻结井。
In order to ensure that well construction passes smoothly through alluvial sections with large water content, freezing method is usually adopted. Beiyangzhuang mine shaft air shaft freezing with a single loop flower arrangement frozen hole, low temperature and large flow rapid freezing program, and the use of visual monitoring, monitoring of information technology, to create the first high-quality Wells Yuzhou mine wells.
