The Resources Dynamic Evaluation Of Neimenggu Jiazishan Molybdenum Deposit Based On Surpac

In current market economy,when the price factor changes,mine production enterprises have to calculate the mine cut-off grade to achieve profitability,and then delineate orebody and estimate reserves so as to guide the actual production and construction of the mine.This paper is mainly using Surpac Mining Software to establish a three-dimensional deposit model and study the dynamic evaluation of its reserves just take the Inner Mongolian Jiazishan molybdenum ore deposit as the example.(1)After in depth analyzed the Surpac system function,defined the database structure,entered the drilling data from Excel,analyzed the characteristics of the drilling data,researched methods and processes of building a geological database,finally completed the Jiazishan Molybdenum Mine geological database.(2)Analysis of the principles and processes of the solid model,based on modeling methods and data characteristics to explore the methods and processes to build a reasonably accurate orebody solid model.Studied the establishment of a complex geological model,in the course of the study,completed building Jiazishan Molybdenum deposit solid model.(3)Based on the constructed solid model of Jiazishan Molybdenum deposit,established and studied the ore block model,analyzed the data structure of the block model,then established the grade model of the orebody,at the same time studied reasonable methods and processes of the establishment of a three-dimensional deposit model.(4)Studied the deposits 3D model visualization and application.Completed the calculation of reserves by 3D geological model,and manage the Jiazishan molybdenum ore reserves dynamicly,when market factors of molybdenum ore is chenged.In summary,Inductive analyzed the problems encountered in the process of building 3D model of the Jiazishan molybdenum mine,Summed up the method of the 3D model of molybdenum mine based on Surpac software and the dynamic management of reserves which would be meaningfully guiding the actual production of mine.
