With the construction of the shaft freeze topsoil continuously improve the speed of the past,the freezing of the construction of the topsoil be difficult to meet the current requirements,and the small excavators in the topsoil of the shaft freeze the use of increased construction progress,and create a certain economic benefits.
随着井筒冻结表土段施工速度的不断提高,以往的冻结表土段人工施工难以满足目前的要求,而小型挖掘机在井筒冻结表土段的使用提高了施工进度,创造了一定的经济效益。
In the frozen surface soil section,information technology construction,is used,and topsoil is dug with by small excavators cooperate with manpower dig with.
在施工赵楼矿主井井筒时,冻结表土段采用了信息化施工,小型挖掘机配合人工挖掘表土, 基岩段采用冷风降温技术和综合防治水技术,在后开工的情况下率先顺利到底,然后施工贯通巷道通风、副井井底,为风、副井顺利到底创造了有利条件,缩短了矿井一期工程的建设周期。
