一、概述某铝矿自1958年建矿以来,一直开采产状为急倾斜的第九号矿区。该矿区包括4个矿段,其中已正规开采的是A矿段。该矿区属龙头山不对称背斜西翼近南北向的倒转单斜构造。含矿层为中石炭系九架炉组,不整合于中上寒武系娄山关白云质灰岩侵蚀面上,整合于中石炭系黄龙灰岩之下,使沉积基底铁矿系直接覆于铝土矿系之上。区内平移断层较多,节理裂隙比较发育,矿体完整性和 I. OVERVIEW An aluminum mine has been mining No.9 mining area with steep slope since it was built in 1958. The mine includes four ore blocks, of which the A segment has been formally mined. The mining area belongs to the inverted south-north reverse monoclinic structure of the Longtoushan asymmetric anticline west wing. The ore-bearing layer is a medium carboniferous nine-stage furnace group that is not integrated with the erosion surface of dolomitic limestone in middle and upper Cambrian Loushanguan and is integrated under the Huanglong limestone of the Central Carboniferous. The sedimentary basement iron ore is directly covered by Above the bauxite department. There are more translatory faults in the area, more developed joint fissures, and the integrity of ore bodies
