The evolution law of deviatoric stress and asymmetric control technology in roadways during panel mining through overlying residual coal pillars
Abstract Close-distance coal seams (CDCS) are widely distributed, and the layout of the upper and lower panels can be divided into “=” type and “+” type. The “+” superposition of upper and lower coal pillars in CDCS caused strong mine pressure, but there are few studies on the panel crossing residua...
