大倾角薄煤层综采实践与探讨

Practices and discussion on fully mechanized coal mining in deep inclined thin seam

薄煤层开采是许多矿井煤炭开采中不可避免的问题。目前,我国薄煤层开采大多仍采用炮采或普采,不仅劳动强度大、生产效率低,而且开采速度慢,影响近距离其它煤层的开采和高产高效矿井建设。论文针对开滦东欢坨矿大倾角薄煤层综合机械化开采所采取的技术措施及所取得的效果,对相关问题进行了分析探讨,提出了大倾角薄煤层机械化开采的有效方法。

A coal mining in thin seam is an inevitable issue of coal mining in many coal mines. At present, the thin seams in China are mostly mined with a drilling and blasting method or a conventional mining method with a high labor tension and low production rate. The low mining speed in the thin seam has influenced other seam mining operations and the construction of the high production and high efficient mine. The paper analyzed and discussed the results and related issues of the technical measures for the fully mechanized coal mining in the deep inclined thin seam of Kailuan Donghuantuo Mine. The paper provided an effective method of the mechanized coal mining for deep inclined thin seam.
