| 摘 要： | 大同矿区坚硬顶板、坚硬煤层(以下称“两硬”)的条件严重制约厚煤层的高产高效开采技术的应用，尤其是采出率难以提高。经过10多年的科技攻关，对顶煤弱化、顶板控制及装备等技术的试验，得出了一种在两硬条件下矿井高产高效及高采出率的综放开采技术，取得较好的经济效益。

| Abstract: | The conditions of hard roof and hard seam in Datong mining area have seriously restricted the high production and high efficient mining technology in thick seams. Specially, it is hard to improve the coal recovery rate. After 10 years of science and research development in the top coal softening, roof control, equipment, and other technologies, a fully mechanized coal caving mining technology with high production, high efficiency and high coal recovery under the two hard conditions was developed with a good economic benefit. |
