冻结法是井筒施工中有效穿过表土层和软岩层的特殊施工方法,一般情况下可采用挖掘机或人工风镐挖掘.周油坊矿在副井施工中遇到了含砾石的坚硬表土层,一般方法很难通过,为此制定了放松动炮的方法通过坚硬表土层,结果表明此方法行之有效,且未引起突水情况

Freezing method isspecial construction method in shaft construction effectively getting through the topsoil and soft rock.Under normal circumstances, excavator or pneumatic pick mining can be used for excavation. Zhouyou?fangmine in auxiliary shaft construction methard topsoil layerwith gravel, it isdifficult to passby general methods, therefore,the relaxation dynamic method of guns was made to get through the hard topsoil layer. The results show that this method is feasibleand effective, withoutcausingwater gushing.
