摘要
黄土岭铅锌矿矿体沿走向呈似层状、波浪状蛇形展布,近地表存在氧化矿,急倾斜薄-中等厚度矿体。黄土岭铅锌矿灵活采用无底柱浅孔留矿法、有底柱浅孔留矿法、后退式挑顶浅孔留矿法三种方案,极大地适应了复杂多变的矿体形态。三种浅孔留矿法均具有机械化程度高,作业效率高,作业环境相对安全,矿体开采适应性强等特点,可供类似矿山借鉴。
For the Lead Zinc Ore of Huangtuling of the planar shape along the strike of the ore bodies are like stratified wavy serpentine,when close to the surface of the primary ore and oxidized ore boundary,inclined thin-medium thickness orebody occurrence characteristics,flexibly put forward by three deformation schemes,including the method of Short-hole shrinkage method without sill pillar,the methods Short-hole shrinkage with sill pillar and the backlift retaining Short-hole shrinkage for mining.The above methods of miningare characterized by high mechanization degree,high operation efficiency,relatively safe operation environment and strong adaptability of ore body mining.If there is mining of similar mines,it can provide reference for them.
