The Research For The Theory Of Wasteless Mining Appraise

The production development during twentieth century is the fastest than before since mankind being, and destroy to the environment of the earth is the greatest, too, of which, the mining industry is the major destroyer, and the major polluter, and the major source of disasters.Mining brings on severe deteriorate to the earth environment, as it affords us useful resource. This deterioration has become the global problem, which increasingly threatens the existing for the mankind. Just as the scholar Eowen.Iadz of Hungary says, now, mankind has come to a crossing for death or revival. Both the mankind and the world would go to die, If mankind could not change current production mariner and thinking manner on effect, and could not alter his consciousness and culture, establishs a entirely new thought for zoology value and zoology ethic.Wasteless mining is a new idea and a developing thought or view, and is an important subject in mining development in 21 century and is increasingly received universal attention at home and abroad, which was brought forward after human has thought over with agony his social historical development. Therefore, it has become an important development direction for our mining industry to protect mine's environment, and to keep mine production with continuance and steadiness for a long periodWithin recent years, many new problems were brought forward through wasteless mining experience, in which, the right design and objective appraise for the wasteless mining is one of its problems. Because it is very short for the idea of wasteless mining to be put forward, there are no relative systemic theories and methods published both at home and abroad. Therefore, it is very important for developing and improving its theories and methods.At the first, the paper describes the importance and the present status of the application of wasteless mining in our country, and gives a special discussion for its conception ,research approaches, and some apply pathways for wasteless mining, then makes a brief description of decision-making and optimizing theories and methods applied in the paper's design and appraisal for the wasteless mining. After that, the author, based on the wasteless mining theories and his research experience, put forward creatively a new method to design and appraise for the wasteless mining, in which the modern applicable visualization technique are applied. At the end the paper gives a practice example to explain its usage and to prove its success. In the paper some of original opinions and methods put forward by the author have great importance to develop and improve the design and the appraise theory system in wasteless mining.As we know, the key to actualize the wasteless is to decrease the waste in mining as possible, and to look for efficient ways to eliminate brought waste.To decrease the brought waste in mining, it is necessary to choose right mining grade of the resource, and to decrease the waste in excavation and mining, based on the specialty of the mining. So it has to design the mining technology and the process rightly, in which, the key is the resource utilization and the mining scheme and the design for mining process.At the aspect of resource appraise, the paper appraises and analyses it from its benefit and its mining grade, and puts forward up their methods for appraise and calculation, in order toTHE RESEARCH FOR THE THEORY OF WASTELESS MINING APPRAISEdecrease the brought waste in mining, and to increase the resource utilization and the benefit of the mining. Furthermore, the criterion and the calculation method for the right ratio of waste and ore in mining excavation are introduced, to control the waste rightly in the mining preparation.The optimization for mining process is mainly to design and choose the best mining scheme and the best mining techniques, which is the one of most important aspect to actualize wasteless mining, and decides the mining benefit and the wasteless mining effect.At the aspect of mining scheme selection, the paper analys...
