某铁矿采场稳定的暴露面积计算分析

Calculation and Analysis of the Exposure Area of an Iron Mine Stope Stabiility

为了计算某铁矿采矿稳定的暴露面积,针对顶板、侧帮、上下盘围岩在不同采场尺寸下的稳定性问题,采用Mathews稳定图方法对其进行了计算分析,得到了某铁矿顶板、侧帮、上下盘围岩在不同采场尺寸条件下的暴露面积,得出了某铁矿稳定的暴露面积大小范围,从而使矿山能更好地控制顶板、侧帮、上下盘围岩的稳定性。

In order to calculate the exposed area of mine stability,the stability of surrounding rocks of roof,side wall and upper and lower wall in different stope sizes is calculated and analyzed by Mathews stability chart method.The exposed area of an iron ore roof,side wall and upper and lower wall surrounding rocks is obtained, and the stable exposed area range of an iron ore is obtained.So that the mine stability of roof,side wall and wall rock can be better controlled.
