Research on the optimizing of product structure under condition of raw coal from multiple-seams and different coal type in a coal mine

When a colliery mined multiple-seams and different coal type,how to determine the production structure so as to gain maximum profit and to utilize the coal resource effectively is an issue should an enterprise considered.The paper using a set of actual data taken from a mine as an example,calculated the product structure and predicted the economic benefit of the planned mining proportion.The result shows that the optimal benefit and production structure could be forecasted with the scientific arithmetic and that a referential proportion of mining different coal seams could be provided.
