摘要
Abstract
Taking the 8916 working face as an example, mastered the forms of the coal wall spalling in full-mechanized caving mining face with large mining height in hard roof and hard coal seam,and analyzed its spalling mechanism. Combined with the practice of 8916 working face, given the inlfuence factors of spalling full-mechanized caving mining face with large mining height in hard roof and hard coal seam,and gave the preventive measures.关键词
