大直径立井井壁结构及井筒断面布置方式的选择

Selection of Wall Structure and Section Layout for Large-diameter Main Shaft

根据麻家梁矿井主立井井筒所穿过岩层的工程地质条件,分析了井筒施工方法的选择和井壁结构的设计,并根据矿井建设规模及选定的提升设备,对井筒断面布置进行了优化。

Based on the engineering geological condition of strata where the main shaft passes in Majialiang mine, the paper presents the engineering method selection and wall structure design. In addition, the section layout of the shaft is optimized in the light of construction scale and selected hoisting equipment.
