This relation is reinforced by real information and the benefits it engenders in the mining economy. Hence, it is important to create optimizing algorithms to reduce the errors of economic calculations. In this work, a logical mathematical algorithm that considers the important designing parameters and the mining economy is proposed. This algorithm creates an optimizing repetitive process among different designing constituents and directs them into the maximum amount of the mine economical parameters. This process will produce the highest amount of ores and the highest degree of safety. The modeling produces a new relation between the concept of the cutoff grade, mine designing, and mine planning, and it provides the maximum benefit by calculating the destination of the ores. The proposed algorithm is evaluated in a real case study. The results show that the net present value of the mine production is increased by 3% compared to previous methods of production design and UPL.展开更多

Therefore, it is of great importance to promote foreign language teaching quality. In this paper, we discuss how to fully utilize the English for Specific Purposes （ESP） theory to enhance professional foreign language teaching quality. ESP refers to a type of teaching concept or approach as the counterpart of English for General Purposes （EGP）, which contains a vast range of aspects. Particularly, we propose two English course design methods based on the ESP theory, that is, 1） language centered curriculum design, and 2） learning centered curriculum design. Finally, experimental results demonstrate that the proposed method can significantly improve teaching quality.展开更多
