立井过侏罗系破碎带井壁结构设计及施工方法选择

Vertical shaft structure design and the selection of the construction method through the Jurassic fracture zone

针对油坊壕矿井侏罗系破碎带凿井技术难题,通过分析研究提出了三个井筒侏罗系破碎带采用冻结法施工方案,并根据现行钢筋混凝土设计规范,提出了高强混凝土井壁结构。

aiming at the technological problem of the shaft sinking through Jurassic fracture zone in Youfanghao mine, through the analysis, proposed the freezing construction method to sink three shafts through Jurassic fracture zone, according to the current code for design of reinforced concrete, put forward the high strength concrete shaft lining structure.
