摘要
彭庄矿井表土段采用冻结法施工,由于精心安排,认真分析,掘砌过程中现场实测,创造出良好的掘砌条件,冻结总工期比设计提前了63天。由于对巨野矿区认识不足区,采用245m处套内壁。本文具体论述了上部砂层和下部粘土层施工的具体对策,使主、副井安全、快速的通过了表土和风化基岩段,
The shaft sinking of pengzhuang colliery was used freezing alluvium technology.The paper summarizes the experiential and technical assistance used in construction,which makes the total process advance sixty-three days.However,for the lack of proper data,the process was once forced to pause to build the inner shaft at the depth of two hundred and forty-five meters.This paper also specially illustrate and analyse the upper quartz and the under alluvium,and it assures the safe and speedy construction.
