浅埋煤层巷道顶板稳定性分类研究
|
摘要
为了对晋北煤业公司矿井浅埋煤层部分顶板进行分类,在一采区皮带巷、一采区轨道巷布置了顶板结构及岩性探测钻孔。结合晋北煤业矿井浅埋煤层实际情况,对顶板结构探测及其岩性力学进行了分析,确定了晋北煤业公司煤矿5上#煤的顶板稳定性分类,为指导安全施工提供了技术保障。
In order to classify the partial roof of the shallow coal seam of Jinbei Coal Industry Company, the roof structure and lithology exploration drilling were arranged in the belt roadway of No.1 mining area and the track lane of No.1 mining area. Based on the actual situation of shallow coal seam in Jinbei Coal Industry Company, this paper analyzed the structure detection and lithology mechanics of the roof, and determined the roof stability classification of 5 up#coal in coal mine of Jinbei Coal Industry Company, which provided technical support for guiding safety construction.
