| 摘 要： | 针对矿山充填接顶困难、充填体承载强度不足等难题,建立了充填接顶率与顶板岩层中最大Mises应力强度的回归模型,探讨了两者之间的定量关系。通过对新桥矿实测数据模拟,发现它们之间存在着显著的线性相关关系。研究表明,当充填接顶率达到50%以上时,充填体强度即可满足要求,从而大大降低了充填成本,对指导矿山接顶充填具有重要意义。

| Abstract: | In accordance with some problems in mines,such as difficulty in roof-contacted filling,unsatisfactory load-bearing capacity of filling body and so on,a regression analysis method is established to determine the quantitative relationship between the rate of roof-contacted filling and the maximum Mises stress intensity in roof rock masses.Through the regression analysis of some measured data from Xinqiao mine,obvious linear relationship between the rate of roof-contacted filling and the maximum Mises stress i... |
