我矿是一座大型露天铁矿,分为兰山(兰家火山)和尖山(尖包包)两个采场,采用平峒溜井运输,溜井布置在矿体中,平峒主要布置在矿体下盘。兰山采场共设1号、2号、3号三个溜井,1号下部为竖溜井、中部为斜溜井、上部为明溜槽;2号为竖溜井;3号下部为竖溜井、上部为斜溜井。尖山采场共设1号、2号二个溜井,1号为斜溜井;2号为竖溜井。竖溜井为圆形,其直径为5米。斜溜井为长方形,其规格为3×4米。平峒至溜井上部垂直高度为293～462米,平峒全长分别为2284米和1280米,穿
Mine is a large open-pit iron mine, which is divided into two stopes, Lanshan (Lanjia Volcano) and Jianshan (Jianbao). The stopes are transported in Pingdingshan and are arranged in the orebody. The Pinghu is mainly arranged in the ore body Under the plate. Lanshan stope a total of 1, 2, 3 three slip wells, the lower part of No. 1 for the vertical chute, the middle ramp inclined well, the upper part of the Ming Chute; No. 2 for the vertical chute; No. 3 for the lower part of the vertical chute, the upper part of the Oblique chute. Jianshan stope a total of No. 1, No. 2 two slippery wells, No. 1 inclined chute; No. 2 for the vertical chute. Vertical chute is circular, its diameter is 5 meters. Oblique chute wells for the rectangle, the size of 3 × 4 meters. Flat 峒 to the upper part of the chute vertical height of 293 to 462 meters, flat 峒 full-length were 2284 meters and 1280 meters, wearing
