摘要
在尖山铁矿破碎机硐室施工过程中对围岩的暴露面积和收敛速率间相关性进行了分析，并对硐室拱顶收敛速率与暴露面积关系进行了回归分析、给出了表达式，指出了尖山铁矿破碎机硐室施工过程中的空顶距、分层高度等参数。
On constructing of underground hall, the exposure area and convergence velocity of surrounding rock is varlable. This paper put up the relativity analysis and regression analysis to the two index with the underground breaker hall of Jianshan Iron Mine,advance the formula between the two index.Mecenwhile, the paper put forword also some constructing parameter,such as control distance of roof control altitude of wall etc.
