The Optimize Study On Mining Method Of Erlihe Lead And Zine Mine

Erlihe lead and zine mine is in the Denfeng county,Shangxi Province.Theâ…¡₁ 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 solvingâ…¡1 ore body mining method of Erlihe lead and zine.on the baises of optimization acts according toâ…¡1 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.
