摘要
Based on the triaxial mechanical property test of coal samples, this paper discusses the bolting mechanism to. the flimsy coal mass in roadway driving along next goaf in fully-mechanized top-coal caving face. Through engineering practice, the bolting supporting effect to coal mass in roadway driving along next goaf is analyzed.
