摘要
针对坚硬致密、节理裂隙不发育、平均厚度 16m煤层的赋存特点 ,通过对顶煤预先综合弱化技术和工作面回采工艺的研究 ,攻克坚硬煤层大放高综放开采技术难题 ,实现安全、高效生产 。
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.
