朝阳矿主副井冻结基岩段深孔减冲光爆法掘进和整体钢模板砌壁设计与施工

Deep-hole reduction flush light demolish driving in main and auxiliary shaft freeze bedrock of Chaoyang Coal Mine and the steel form cast-in-place wall of a well design and construction

朝阳矿主、副井冻结基岩采用3 3m深孔减冲光爆法施工,冻结段外层钢筋混凝土井壁平均掘砌速度分别达104 2m/月和106m/月,为爆破界探索出了前所未有的实践成果,给出了冻结壁、冻结管爆破安全和冻结段整体钢模板高度的理论计算.

The main and auxiliary shaft freeze bedrock of Chaoyang Coal mine construction with 3.3m deep-hole reduction flush light demolish are described, average driving speed of outer layer R.C.wall of a well in freeze Section are 104.2m/month and 106m/month. It not only shows the achievements, but also shows the theory calculation of freeze wall of a well and demolish safety.
