立井基岩
3) shaft lining in bedrock section
基岩段井壁
1.
Ground pressure stress of shaft lining in bedrock section of deep vertical shaft and extra deep shaft is revealed by theoretical analysis,which provides a basis for optimized design of shaft lining in bedrock section.
揭示深立井及超深立井基岩段井壁地压应力的理论分析方法,为基岩段立井井壁的优化设计奠定基础。
4) shaft bedrock driving
立井基岩掘进
1.
Because small width, vertical development and no crosswise development of the micro-crack can not produce the good effect of injecting in the construction of shaft bedrock driving, it is a good way to adopt the injecting technique of the high-power and large-diameter blasting propellant to produce crack.
在对立井基岩掘进施工裂隙水的治理中,因微裂隙宽度小、竖向发育、横向不发育而导致注浆效果不甚理想的情况,提出采用高威力大直径爆破药柱爆炸止裂注浆技术,以沟通横向裂隙和扩大裂隙区半径,加大注浆帷幕的范围和强度,从而达到治水和加固围岩的目的。
5) the freezing of shaft
立井冻结段
