| The human being living space is limited. It has been acknowledged how the human reasonably develop and utilize resources to meet subsistence and development of human society. China is nation with abundant mineral resources, which is a big disparity with the developed mining countries in technology and the management levels. Mining industry in China should implement intensive and mfomationization way, bravely meet the challenge, grasp the opportunity of the Digital Earth and the Digital Earth strategy, decisively improve to innovate technology and reform management, it is irresistible general trend to Strategy of Digital Mine for traditional mining industry walking out predicament and sustainable development.The paper summarize the present situation and the developing tendency in digital deposit at Home and Abroad, sum up digital deposit existing questions in China.,and propose measures of the domestic digital deposit .Choosing Micromine mine software as a platform, the author establishes digital deposit models for the ore bodies of Wandongshan ore segment in Beiya gold deposit. Digital deposit include digital deposit model ,digital terrain model , exploration and exploitation engineering system model, geophysical model, geochemical model. Through the digital deposit research, the paper mainly obtained the following results1 The academic results(l)By the statistical analysis of the raw data, the primary sample and composite sample present normal distribution after taking logarithm.(2)By the calculation and simulation of Variation, to build the theoretical model of Variation for the deposit. And to do the geological explanation, to primary discuss the spatial change shapes of the deposit and its influential factors.(3)For the first time to build the digital deposit in Beiya gold deposit, to realize the digitalization and visualization of the useful information of the ore body.(4)By the digital deposit, to sum up the regularity of mineralization and enrichment of the deposit with the method of mathematics and graphs, to change the traditional qualitative analysis to quantitative analysis.(5)To prognoses gold mineralization in deeper and outer of Wandongshan ore segment ,Beiya gold deposit.2 The practically applied results(l)To build the original database, to realize the electronic, standardization and dynamic inquiry, it is important to protect and secondary exploit for datum.(2) By the establishment the digital deposit model, to realize computerization of reserve and grade calculation of deposit, and automation of plotting plan and section of deposit.(3)After the establishment of the digital deposit model, on the base of the cost of the mining, mill run, metallurgy, conveyance, management and the market price of the product, considering the sufficient and reasonable utilization of the resource, to dynamic plan draw the deposit, doing contrast and choosing the optimum plan of the deposit exploitation.(4)By the establishment of digital terrain model and exploration and exploitation engineering system model, to assist exploitation designment of deposit. |
