一、矿体賦存情况及开採技术条件马拉格锡矿的铅矿位于老阴山区,矿床成因类型属中温热液矿床。矿体在走向上成矿节产出,呈雁行状排列。采场多以矿节划分。矿石为土状氧化矿,较松软,f为2～3,主成分为褐铁矿、磁铁矿。铅品位平均为7％。顶底板为大理岩,f为7～8,节理层理比较发育,形成一定空塘即坍塌冒落,逐渐陷落至地表。矿体倾角40～85°,厚度一般10米,厚的20米,薄
First, the occurrence of ore bodies and mining technology conditions Lead mine in the Malage tin deposit is located in the old Yin Mountain area. The genesis of the deposit is of medium temperature hydrothermal deposit. Ore body in the direction of ore-bearing section output, was geese arranged. Stopes are divided by mine section. Ore ore oxide soil, more soft, f is 2 to 3, the main component of limonite, magnetite. The average grade of lead is 7%. Top floor is marble, f is 7 ~ 8, more rational development of the joint layer, the formation of a certain collapse of the empty pond that is, and gradually fallen to the surface. Ore body angle 40 ~ 85 °, the thickness of 10 meters, 20 meters thick, thin
