一、概述黄田矿区系震旦纪浅海沉积的宣龙式铁矿床,矿体倾角为15°～25°,设计年产量40万吨。整个矿床划分为五个区,目前只开采四区和五区。沿矿床倾向自上而下分为十三个阶段,阶段高18—20米,阶段斜长50—60米,矿区建设分为二期,零平巷至七平巷为一期工程,八平巷至十三平巷为二期工程。四区一期工程采用平峒一肓斜井开拓,五区一期工程采用斜井开
I. Overview The Huangtian mining area is a sedimentary Xuanlong iron ore deposit of Sinian shallow sea with a dip angle of 15 ° ~ 25 ° and an annual designed output of 400,000 tons. The entire deposit is divided into five districts, currently only four districts and five districts. According to the deposit tendency, it is divided into thirteen stages from top to bottom, the stage is 18-20 meters high, the stage is inclined 50-60 meters long, the mining area construction is divided into two stages, Alley to Lane 13 for the second phase project. Four districts of a project using flat 峒 a 肓 inclined shaft to open up a five-phase project using inclined open
