Linear-Programming-Based Coal Preparation and Blending Technique

摘要

The purpose of this study is to formulate and code a mathematical model of the coal blending and preparation process at the Martiki Coal mine in Lovely, Kentucky, which will reduce wash loss by improving the daily tonnage and specific gravity decision. A model of the Martiki Coal Corporation blending and preparation process is developed with minimization of wash loss as the objective. Solution is by iterative linear programming using the Tucker Tableau algorithm on an Apple II microcomputer. Output serves as an aid to preparation plant personnel in making the daily specific gravity and tonnage decision. Each percentage reduction in Martiki's 1984 wash loss would have decreased disposal costs and increased revenues by approximately $550,700.
