| The application of 3D geological modeling technology to build a mathematical model provides a scientific tool,reasonable optimization of mine 3D models will make abstract complex orebody distribution becomes intuitive simple and efficient, the mine mining design and production decisions play a very important influence.Based on Cheqiongzhuobu gold(antimony) mine as the research object,based on the basis of geological data through to the mining strata structure orebody characteristics,ore characteristics,wall rock alteration and mineralization fluid research,analyzes the Cheqiongzhuobuh gold antimony deposit genesis,and established the Cheqiongzhuobu gold(sb) mine geology database,three the entity model of the ore bodies,the block model. Entity model can more accurately reflect the relative position of ore body in space, and the extension trend of vertical direction and horizontal direction, pointed out the situation,the scientific planning of production for mine provides intuitive clear basis. In this paper,the principle of geostatistics applied to block model,the drilling data processing specific values,build a reasonable variation function,the ore body of the block model is established in this paper,build up the grade model, then conclude reserves calculation method, the traditional reserves calculation method and Surpac software provides the methods of comparative analysis,inspection precision rationality of the calculation of reserves.Basic geological data of the mining area through the comprehensive analysis of the three-dimensional has a more reasonable explanation to the ore deposit origin,by constructing orebody model showed the ore body in three-dimensional space,clearly express the orebody occurrence location of three dimensional space and relations,by building its grade block model,intuitive to observe its grade distribution and trend, and calculation of reserves of ore deposits,ore deposit for the future development,and provided guarantee to improve mine economic benefit. |
