Abstract

Abstract

Taking an underground mine in Panxi as an example, the exposed area of the stope was estimated based on Mathews stability diagram method and empirical analogy method. It is recommended that the allowable exposed area of the stope roof is 800 to 1200 square meters, and the allowable exposed area of the ore body side is 4000 to 5000 square meters. Based on FLAC^3D numerical simulation analysis, the stope structure parameters were optimized. The results show that with the increase of stope length and stage height, the maximum tensile stress, maximum compressive stress and maximum shear stress around the stope increase. Combined with the existing development system of the mine, it is recommended that the stage height of an underground mine in Panxi is 60 meters and the length of the stope is 60 meters.
