Stress distribution and surrounding rock control of mining near to the overlying coal pillar in the working face
The occurrence of overlying coal pillar (OCP) exerts a strong effect on the stress and strain distribution of the surrounding rock in the stope. In this paper, the stress distribution characteristics are analyzed via the numerical calculation with the account of OCP presence or absence. In addition,...
