| Abstract: | Base the seam conditions of hard, density, undeveloped joints and cracks, and 16 m average thickness, with the pre-comprehensive weakening technology and the mining technology study of the coal mining face, the difficult issue of the fully mechanized high top coal caving mining in hard seam has been overcame with a safe and high efficient production. The mine economic benefit has been improved. |
