[Abstract]:With the development of 3D visualization technology and the popularization of 3D geological software, our country pays more and more attention to the popularization and application of 3D geological software. Three-dimensional geological software can be widely used in the establishment and management of mine geological database, the 3D display of orebody solid model and geological structure, the estimation of geostatistical reserves, and the design of mine production. Open-pit mining boundary optimization and production schedule and other aspects. The application of 3D geological software has greatly improved the level and working efficiency of mining industry. This paper summarizes and analyzes the research status of 3D visualization modeling and the development and application of 3D mining software at home and abroad. According to the modeling flow of Micromine 3D geological software, the model of Meiling copper-zinc gold ore body is constructed, and the reserve of Meiling copper-zinc gold deposit is estimated by distance inverse proportional weighting method. The model of copper zinc ore body grade in Meiling is established. The variation function of ore body in different directions is calculated by using variation function method as main analysis tool and copper grade value as regional variable. According to the variation range of variation function model of orebody strike and tendency direction, the exploration net degree of ore deposit is determined. The best value of copper metal price under different market conditions is obtained by using the open-air boundary optimization function module of Micromine software. The main research results of this paper are summarized as follows:. (. 1) the model of Meiling copper polymetallic deposit is constructed on the platform of Micromine. It includes the establishment of 3D geological database and the establishment of solid model (orebody model, main fault structure model and terrain model). Based on the statistical analysis of the results of borehole sampling, the Cu grade model of Meiling copper body is constructed by choosing the distance weighted inverse ratio method. According to the estimated reserves of the copper deposit, the grade tonnage curve of the ore body of Meiling deposit is drawn, which can guide the dynamic management of the mine. By analyzing the variation of shape, thickness and grade of M10 and M12, it is concluded that the main ore bodies in Meiling are stratiform like simple type, thickness is stable type, copper grade is non-uniform and uniform type. There is a positive correlation between copper ore body thickness and copper grade. The Meiling deposit is divided into two data domains to analyze the rationality of exploration network. The copper grade of ore body in the area of M63-M19 and M15-M16 is calculated in different directions, respectively. Experimental variogram. Based on the structural analysis of the variation function model and the variable-range value of the variable-function curve model in the direction of strike and inclination of the orebody, the distance of exploration is determined. The results show that the area of the exploration line No. 1: M63-M19 is located in the area. It is suggested that the degree of exploration net is 73 m 脳 84 m; In the area of M15-M16 exploration line, it is suggested that the exploration net should be 36m 脳 70m.f.) the function module is optimized according to Micromine open-air boundary. The design scheme of mining boundary under different copper market price is studied. The seven simulated mining boundary design schemes can provide dynamic management basis for the development of Meiling mine, that is to say, according to different copper metal market prices, the best open-pit mining design scheme can be reasonably adopted.
