摘　　要：黄兰矿区龙潭煤系主要形成于中二叠世晚期的层序1海侵体系域阶段,古环境对煤层的形成控制较为明显,厚煤层呈北东向形成于三角洲和滨岸平原泥炭沼泽环境中;黄丰桥、兰村向斜由南往北煤层的稳定性变好。在找矿应用中先期利用矿井编录成果分析矿区构造与成煤条件;将地质效果与降低勘查成本相结合,坚持勘查技术手段为地质服务的目的,提高了区内地质工作的研究程度,实现了矿区新增煤炭资源储量达数亿吨。Longtan coal series in Huanglan mining area is mainly formed in the sequence of transgression system in the late of the middle Permian, and the formation and control of the coal seam is obvious in the paleoenvironment. The thick coal seam is formed in the northeastern direction of the delta and the coastal plains peat swamp environment in Huangfengqiao, Lancun diagonal from south to north coal seam stability is better. In the application of ore prospecting, the mine structure and coal forming conditions are analyzed by using the results of mine catalogs in advance. The combination of geological effect and reduced exploration cost is the purpose of geological service, and the research degree of geological work in the area is improved. Mine reserves of coal resources up to hundreds of millions of tons.
