Analysis for the Safety Status of Rock Mass Material in Mining Hole Using the Theoretical and Numerical Method

Abstract:

The mechanical behavior of rocks is nonlinear. Most conventional calculation of stress around the mining hole is based on a linear Mohr–Coulomb failure criterion. In the past few years, there has been an increasing recognition that stress–strain relations do not remain linear, even for low stress levels, and the strength parameters of both geomaterials depend on stress levels. In recent years, many efforts have been focused on stability problems of geotechnical structures with the theoretical and numerical method. In order to further understand the stress state to predict the safety degree of mining hole, in this paper, analysis for the safety status of rock mass material in mining hole using the theoretical and numerical method are done to give guidance for the real practice.
