一、地质赋存情况及采矿方法的确定 (一)地质赋存情况:岭前矿7号脉矿体,为接触交带硅(?)岩类型浸染矿体。走向近似东西,延长达1000余公尺。向北倾斜,倾角为20°～40°,延深达150公尺左右。厚度变化由0.8～20余公尺。近地表处氧化较多。矿体分枝,复合,膨缩现象频繁,一般可将整个矿体分为顶、底秀两条矿脉,分支处夹石厚度由几公分至十余公尺,最厚者达30公尺,靠顶盘矿体是辉钼矿赋存
I. Geological occurrence and determination of mining methods (I) Geological occurrence: The No. 7 vein ore body of Lingqian Mine is in contact with the intercalative silicon (?) Rock type dipping ore body. Towards similar things, extended up to more than 1,000 meters. Inclined to the north with an inclination of 20 ° ~ 40 ° and a depth of about 150 meters. Thickness changes from 0.8 to 20 meters. Oxidation near the surface more. Ore body branching, compound, shrinking phenomenon is frequent, the general can be divided into the top ore and the end of the show two veins, branches of the thickness of a few centimeters to tens of meters, the thickest of up to 30 meters, The top plate ore body is molybdenite ore
