Summarization of thin seam mining and research on thin seam mining in Shenfu Dongsheng Coal Field;

Present status and development of fully mechanization technology for thin seam mining;

This paper study the long hole loosen blasting technology for bottom floor rock of fully-mechanized face in coal seam based on theoretical analysis, such as Explosive Mechanics, Rock Mechanics and Damage Mechanics etc, and what s more, the commercial testing in status quo has verified it.
