Coal Mine Abutment Pressure Distribution Based on a Strain-Softening Model
The coal in front of the mining face presents strain softening deformation characteristics. An analytical model is proposed to simulate the abutment pressure distribution over the coal in front of the mining face under elastic and inelastic conditions. A new theoretical formula is derived from calcu...
