概述大冶铁矿尖林山矿体埋藏较深,倾角缓矿体位于铁山侵入体与下三迭纪大冶灰岩的接触处。成因类型属于接触交代高温热液矿床。含矿层的上盘围岩主要是闪长岩,f=8～12稳固性强。现采用无底柱分段崩落采矿法。矿块构成要素:垂直走向布置,阶段40～70米,分段高10米,进路间距10米,断面(宽×高)4×3米~2呈菱形布置,溜井间距沿矿体走向50米,倾向方向50～150
Overview The Daying Mountain ore body in Daye Iron Mine has a deeper burial depth. The slow dip ore body is located at the contact point between the Tieshan Intrusion and the Lower Triassic Daye limestone. The genetic type belongs to the contact metasomatism high-temperature hydrothermal deposit. The main wall of the ore bearing rock is diorite, f = 8 ~ 12 strong stability. Is the use of non-pillar caving mining method. Lime elements: vertically arranged, stage 40-70 meters, 10 meters high, the road spacing of 10 meters, section (W × H) 4 × 3 m ~ 2 diamond-shaped layout, spacing of the slide along the ore body to 50 Meters, the direction of 50 to 150
