Abstract:

In the process of exploring the optimal depletion mode of mineral resources，the author had previously published two papers，which respectively discussed the optimized mining distribution question of the ore about two or three different grades and reserves，and formed a relatively simplified prototype of a mathematical model of the mineral resources optimal depletion，but it was not always coincide with the actual conditions of the mine （the grade and reserves of ore often are multifarious）.In order to further improve and establish a more realistic optimal depletion mode of mineral resources，we take the optimized mining distribution of aurum ore as an example.Through scientific abstraction，simplification，and using the mathematical method and quantitative analysis，to deduce，induce and summarize the optimized mining distribution problems of many kinds of different grade and reserves of ores，what was obtained is a general applicability，easy to operate，intuitive and simple optimal depletion mode of mineral resources.We think that the model has achieved the desired goal，and has certain utility value and exploratory significance，and can achieve optimal depletion of mineral resources.
