一、1号试验采区的基本情况二矿区1号试验采区为中瑞技术合作的试验采区。采区对西部1号矿体进行回采。采区范围在14~(+25)～16~(+25)行线;1300中段～1250中段之间,长100米,高50米。采区内富矿厚约100米,上盘贫矿较厚,下盘贫矿较薄,贫矿两侧为超基性岩体。超基性岩体上、下盘直接围岩为:中薄层大理岩(Ⅲ_3)、肉红色花岗岩(V)(见图1)。
First, the basic situation of the No. 1 test mining area No. 2 mining area test mining area for the Sino-Swiss technical cooperation test mining area. Mining area on the 1st West ore body mining. Mining area in the range of 14 ~ (+25) ~ 16 ~ (+25) line; 1300 middle ~ 1250 middle of the length of 100 meters, 50 meters high. Mining area rich in ore thickness of about 100 meters, on the plate thicker lean mine, lower plate lean mine thinner, lean ore on both sides of the ultrabasic rock mass. On ultramafic rocks, the direct surrounding rock of the lower plate is medium thin marble (Ⅲ_3) and meat red granite (V) (see Figure 1).
