Stress environment of entry driven along gob-side through numerical simulation incorporating the angle of break
Angle of break (AOB) is the acute angle created by the coal seam bedding plane and caving line formed by roof strata movement after extraction of a longwall panel. It has a significant influence on stress redistribution both in the gob and abutment. Throughout numerical simulation investigations up...
