冻结施工技术在西部某矿井井筒工程中的应用

Application of freezing construction technology in the shaft of a western coal mine

基于西部某矿进风立井地质水文特点,选用了单圈插花长短腿布孔设计方案,并对冻结施工技术进行了阐述,既为掘砌施工创造了良好的施工环境,又取得了较好的经济效益,为西部类似地层冻结井方案设计提供借鉴。

Based on the geological and hydrological characteristics of a western coal mine,the design of air intake shaft is the single ring flower leg length hole layout scheme. It describes the freezing construction techniques,both thinking about a good work environment creating for the continuous excavation and construction,and good economic benefits achieving. The frozen shaft scheme design provides references for the similar strata in western.
