The Application Of Mathematical Programming In The Mining Scheme In Open Pit

Aiming at the actual problem of decreasing quality of the JiDong limestone mine and the continuing need of the higher quality ore which come from the market, in order to realize the goal that the mine can continue to develop and realize the benefit of the social and economic , the paper mainly discusses the product programming (quality neutralization plan) in the next 5 years with mathematical programming.The paper expounds the status quo of the application of mathematical in all sorts of corporation and in the mine corporation, and then indicates the significance of the method in mining scheme. The paper introduces the situation and the problem of the mine at present, put forward the reason of using the linear programming. Then using this method set down the mining scheme and quality neutralization plan. The result expounds that it can bring great economy benefit with this method. The paper discusses the extend of the linear programming: a kind of fuzzy programming, explains that the method is more flexible and reasonable than the linear programming in solving the mine product programming in some aspects. Then using the fuzzy programming to set down the 2004-year product programming. The paper explains that the fuzzy programming is better than the linear programming in effect in some aspects. In the part of software introduction, the paper introduces the linear programming and mine-mixing software in detail and offers the linear programming of mine-mixing during the daily scheme.The created point of the paper is set ting down the product programming of the mine using the mathematical programming, especially in using the fuzzy linear programming. It is more valuable to the mine cooperation, which has lots of variable, and contains lots of nondeterminatal factor and fuzzy character.
