East Lead And Zinc Three-dimensional Deposit Model Development And Application Of Research

Deposit model is a digital mineralizing model of orebody spatial morphology, spatial distribution of resource, geo-environment of deposit and mining engineering. It is based on information technology and the theory of geostatistics. It is the foundation to realize reserves estimation, CAD, production scheduling Establishment, virtual simulation of stoping process and production management. 3D digital deposit model is the foundation of construction of mine informatization.3 D digital deposit model is a group of related real 3D space digital deposit modeles. It usually includes geodatabase, solid model and block model etc. There were interdependent relations among them, and they are created in sequence. The author has discussed the method of creating geodatabase, solid model of orebody, surface terrain, mine engineering and block model, according to the flow chart of constructing deposit model. This paper analysed the distribution of lead and zinc grade in Daliangzi lead-zinc deposit by geostatistics. The search ellipsoid was set up to enhance the adaptability of distance power inverse ratio method to anisotropic deposit, and the grade and the reserves of ore and metal are estimated by this method. The calculated results are reliable and consistent with practical matters of deposit by contrasting the former results of geological exploration.The visual display and interaction of orebody, geologic structure, mine engineering and surface terrain in real 3D space are realized by establishing 3D digital deposit model. It affords an environment and means to mine engineering design based on real 3D space. It provides basis for scientific production scheduling Establishment, too.A solution to building informational and digital mine is offered after the practical matter of production in Huidong lead-zinc mine analysed. The scheme of setting up integrated communication system in surface and underground based on the leaky cable technology and how to create virtual mine based on virtual reality technology are studied. Informational and digital mine establishment is a foundational work of mine. It affects production technology and management roundly and chronically. The application of research results that were achieved in this paper will improve the level of production technology and management in mine remarkably.
