煤矸石堆积模型

Mathematical Model of heaped-up Gangue

本文就煤矿堆积煤矸石费用问题建立数学模型 ,就不同的征地方式 (建矿初期一次性征完 2 0年所需用地和分批征地方式 )和煤矸石堆数进行了分析讨论 ,得出结论 :在建矿初期一次性征完所需用地 ,且所有煤矸石全堆成一堆的方案是最优的 ,并就不同的出矸率计算出该最优方案的总费用 。

This paper discusses the expenditure of heaping up gangue in coalfield and analyzes different land purchase ways and the heaping up number,from which it comes to a conclusion as follows:The least expenditure is needed only in the case that all land are purchased once at the beginning of coal extraction,and that all the gangue metals are piled in one heap.Also, for the different gangue production rate,a mathematial way of figuring out the total expenditure mentioned above is given.Last but not least,based on the different gangue production rate,a formula of working out the lowest annual average expenditure is accordingly provided.
