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

Abstract

Abstract: 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.

Key words: Stope, Mathews stability chart, exposed area
