摘要
结合某矿二副井箕斗装载硐室的施工实例,数值模拟分析了硐室施工中各个阶段围岩位移、应力的分布特点,确保了硐室开挖的安全进行,并为硐室的支护设计奠定了基础。
Combining with the construction of the second skip loading chamber auxiliary shaft of some mine,the paper has the numeric simulation analysis of the distribution features for the displacement and stress in the chamber construction,and ensure the safety of the chamber excavation,so as to lay the foundation for the support design of the chamber.
