摘要
就王坡井田3号煤层综放开采的可行性在煤层强度、顶底板情况、煤层结构和节理裂隙等5个方面进行了顶煤冒放性评价,并运用了天地公司开采所事业部的综放开采顶煤冒放性评价软件进行了评判,认为该煤层采用综放开采是可行的。在工作面配套设备方面实现了高可靠性,提出了搞好3号煤层瓦斯抽放工作是综放工作面实现高产高效的关键技术。
the caving capability of top-coal are evaluated in five aspects of intensity of coal seams, properties of roof and floor, structure of coal seams and joint cracks in this paper. And software from Tiandi Company is used for evaluating 3~# coal seam of Wangpo mine. Application of the longwall with top-caving mining in the coal seam is feasible. High reliability can be achieved in aspect of coal face equipment matching. The viewpoint is brought forward that the work of gas suction in 3~# coal seams is the key technique for realization of high output and efficiency in longwall with top-caving mining face.
