【摘要】 二里河铅锌矿区位于陕西省凤县坪坎镇境内,Ⅱ₁号矿体是本区的主矿体,金属储量占总储量的97%。Ⅱ₁号矿体的基本特征是:鞍部矿体厚大、倾角缓、构造多、品位高,两翼矿体厚度变薄、倾斜-急倾斜,品位贫富不均,鞍部与两翼形成一整体呈鞍状向东潜伏延伸,该类矿床是国内外公认的开采难度较大的矿床。因此,研究一种技术上可行,经济上合理和安全可靠的采矿方法对矿山的可持续开发具有重要意义。论文旨在解决二里河矿区Ⅱ1号矿体的采矿方法,在优化研究时根据二里河矿区Ⅱ1号矿体的开采技术条件,在初选方案的基础上,分析了影响采矿方法选择的因素,建立了采矿方法选择的层次结构模型,采用模糊综合评判理论对五种基本采矿方法方案进行了优选,结合鞍部矿体和翼部矿体的附存特点,得出适合二里河铅锌矿的采矿方法,即采用“底盘漏斗分段空场法、普通分段空场法、浅孔留矿法”灵活开采翼部及鞍部矿体。论文在优选采矿方法的基础上,完成了底盘漏斗分段空场法、普通分段空场法、浅孔留矿法的设计,并详细计算了三种采矿方法的标准矿块矿石采出量。论文并根据生产实践,以典型矿块的开采为例分析了三种采矿方法在二里河铅锌矿的实施效果。最后给出了结论和展望。更多还原

【Abstract】 Erlihe lead and zine mine is in the Denfeng county,Shangxi Province.TheⅡ₁ ore body is the bigest body in Erlihe mine which possessed of 97%in all metal reserves.The ore body of the Erlihe mine is a nek deposit which is thickness,obliquity delay,Being very complex mining technology condition,It is very difficult to mine. How to economic and safety mine the ore resource,it is a very important problem for the Erlihe mine,So It has a huge practice value to choice a right mining method and mine the ore.The paper is for the purpose of solvingⅡ1 ore body mining method of Erlihe lead and zine.on the baises of optimization acts according toⅡ1 ore body mining engineering factor of Erlihe lead and zine.mine in the primary election plan foundation,has analyzed the influence mining method choice factor,has established the mining method choice hierarchical structure model,used the fuzzy synthesis judgment theory to carry on optimal to five kind of basic mining method plan,the union saddle ore body and the wing department ore body attached save the characteristic,obtained Erlihe lead and zine mine the mining method,namely the use "the chassis funnel partition vacant place law,the ordinary partition vacant place law, shallow Kong Liukuang the law" mined the wing department nimbly and the saddle ore body.The paper in the optimal mining method foundation,has completed the design of funnel partition vacant place method,the ordinary partition vacant place method, shallow Kong Liukuang the method design.And in detail calculated three kind of mining method standard ore block ore to pick the output.The paper acted according to an author many year work experience,Has analyzed three mining methods take typical ore block mining as the example in Erlihe lead and zine mine implementation effect.The paper finally has given the conclusion and the forecast.更多还原
