Mine Supervision Appraisal

Based on studying the domestic and international relative materials and synthesizing the development information of mining industry, referring to the characteristics of the mineral resources, the thesis clarifies the necessity of the supervision and management to mine and through the analysis and summary to the state of the domestic and international mine supervision and management, defines the study range, contents and significance of the thesis.The work of the thesis is mainly inside. Combining some previous and present practice and perceptual knowledge acquired during the mine investigation, through the study and analysis to all parts of contents in mining industry chain, the thesis abstracts the possible supervision contents of all parts in this chain, then, narrates and analyzes to work mine points, supervision basis and the modes and methods of the mine supervision so that the all the supervision acts are applicable in practical work. What's more, it should be done to shorten the supervision time and frequency under ensuring the supervision effect and increase the supervision efficiency.The thesis narrates some important economic and technological indexes which may influence the final profit of the developing mineral resources, including the mine capital construction investment, mine reserves, ore grades, mining stoping rate, ore loss rate, ore dilution rate, oredressing recovery percentage, mine production cost, mineral products sales price, etc and supervises these indexes by the proper ways.Furthermore, the thesis analyzes the influence degree of the indexes to resource profit and lists them in order from strong to weak in order to emphasize or accept or reject reasonably during the mine supervision according to the actual need of mine development.After studying comprehensively all relative contents, the thesis constructs mine supervision appraisal system. The system covers all the key parts of the whole mining industry chain from the mineral resources exploration to mineral products sales in order to improve the systematicness and practicality of mine supervision. For matching the mine supervision appraisal system, the result after a series of studies, the thesis constructs a mimic mine supervision appraisal agency according to the supervision essence and the usual organization pattern. What's more, in the thesis, the author gives some advice on the management, operation and team building.The mine supervision appraisal system in third chapter of the thesis is suitable to the fine supervision to the whole process, including the mineral exploration and mine construction and operation or different stages based on the needs. For improving the efficiency of the mine supervision, the thesis chooses the mine reserve, mine production, ore dilution, mine production cost, mineral products price accordingly to consist of the mine supervision simplified appraisal system and narrates the supervision significance and implementing acts of the five indexes in details. The system may make the mine supervision more efficient and reach the effect of from points to sides and controlling the overall the production through supervising the key indexes. The system is especially suitable to the stage of the mine production and operation.
