Residual Strength Estimation Method of Soft Coal Based on Equivalent Residual Strain Ratio
In underground mining engineering, the residual strength of surrounding rock has an important influence on the secondary stress distribution caused by excavation. Generally, the residual strength of coal can be measured by experiments, but for soft coal, due to its large postpeak deformation charact...
