| Abstract: | In accordance with present operation condition in Xinqiao Mine discussion on highly linear relation rate of supporting pit roof and strength of the biggest Mises stress in roof rock masses,was made using finite element and regression analysis method.The result of prediction is stability of roof rock masses,when the rate of supporting pit roof is past 50%.It can be helpful for other related mines. |
