摘要
经对大柳塔煤矿回采方法及效率的研究,总结了提高回采率的一些经验和做法;通过优先合理布置综采面,在不宜布置综采面的边角区域合理布置旺采;再通过旺采工艺改革,积极提高旺采回采率,实现了煤炭资源的合理开发和利用。
The paper studies the mining methods and efficiency of Daliuta mine and concludes some experiences of increasing the recovery rate. Fist, fully-mechanized mining faces are arranged rationally in advance, and then in some corner areas, Wanggeweili mining technology is adopted. Finally, the Wanggeweili mining is reformed to increase the recovery rate to realize the rational development and utilization of coal resources.
