红墩子矿区深厚冲积层冻结法施工实践

Practice on Frozen Construction of Deep Alluvium in Hongdunzi Mining Area

通过红墩子矿区红四煤矿风井井筒深厚冲积层冻结施工的设计、施工和信息化检测,获得红四煤矿不同地层岩性冻结壁发展综合规律,提出了冻结施工的一些建议,为今后类似地层井筒冻结方案设计优化及冻结孔合理布置提供借鉴,具有一定的参考价值。

By analyzing the design, construction and information inspection of frozen construction of deep alluvium of air shaft in Hongsi Colliery, Hongdunzi Mining Area, the paper introduced the comprehensive rules of rock frozen wall developing in different formation and put forward some suggestion on frozen construction, which provided reference and had a certain reference value for the design optimization of shaft frozen scheme and the reasonable layout of freezing hole in similar formation.
