The Lanping North Factories And Mines Segment Digital And Technical And Economic Indicators To Optimize

Under the background of missing in the resources, environment worsen, population inflation and economic sustainable development and economic globalization, the reasonable utilization and development of the mineral resources is becoming a outstanding problem. Society makes higher claims for the geological science which however cannot meet the needs of social development. Carrying on 3DGM, strengthening the quantitative valuation of the mineral resources, raising the processing accuracy of the geology data to realize the aim of dynamic management of mineral enterprise, the full reasonable exploitation, declining the cost and raising the social economic effects , which is an important thing that relate to sustainable development of mineral enterprise.For many years, geologist and mining industry experts have been hoping to interpret and outline more accurately the geologic body underground to understand more accurately the 3D information of the geologic body underground (including stratum, mineral body, fault, fold structure and so on) , calculate mineral body reserve quickly and accurately and understand the spatial grade distribution of the mineral body, so that it can instruct us in exploring the mineral resources effectively, which bring the reform from the traditional mining industry to modern one.The author analyzed the existing problem in developing the mining informationiztion , summarized briefly the theory and technique of the geostatistics, the basic theory of variation function especially the Kriging reserves estimation , compared and analyzed the function of the popular international mining software, established 3D digital mineral deposit models for Lead Zinc Ore of Lanping with the software package of Mathematic-economical Model of The Deposits combining the software function of SURPAC. The achievements as follows:(1) Built up the original geology database after checking accurately the original data and processed reasonably the abnormal grade. The mineral enterprise can renew, save, deliver, express and search their need data at any time.(2) Analyzed the distribution regulation of sample including sample total, average, variance, Standard deviation, frequency distribution and the grade distribution of sample and plotted grade distribution histogram and probability relative frequency graph, the result display that the primary sample and composite sample presents logarithmic normal distribution.(3) Interpreted and determined mineral body underground according to the geological sections and data of mine to set up 3D visual model of mineral body.(4) Setted up theory variation function applying normal Kriging and globosity model to provide reference for analyzing regulation of deposit and instructing exploring deposit .(5) Estimated the value of grade of mineral body applying normal Kriging to set up spacial grade model of mineral body. As a result found out the 3D spacial distribution character of grade of mineral body and summarized the regulation of useful element enriching of mineral body.(6) Outlined dynamically mineral body with many schemes and compared them according to mineral deposit mathematical model and the cost of mining, smelting, transporting .managing and the price of mineral production in market in order to provide reference for enterprise selecting the best mining scheme.The foundation of mathematic-economical model of the deposit is to provide scientific reference for mineral enterprise realizing digital dynamical management, developing and making use of mineral comprehensively, raising the social economic effects of developing mineral resources and to provide a comprehensive information terrace for the aftertime development of mineral enterprise.
