| Recently, our minings fell across unprecedented survival and developed crisises: resource shortage, labour productivity lowlihead, manufacture's capability to compete low, environmental deterioration and so on. Mining undercapitalization, technology and means lag are the mostly causes. It is difficult for traditional mining industry to determine the ore body boundary more accurately and visually, learn about 3D formation of the geologic body underground, interpret and determine the geologic body underground accurately, calculate ore deposits with high speed, grasp the spatial grade distribution law of the ore body, so that it can instruct us in exploring the mineral resources effectively. However, the realization of mine digitaled is the effective approach to resolve these problems."mine digitaled" is the token of the mine whole numbers nowadays, that is, geographical coordinate as the criterion for integrating all information about diggings geography, ore-body geology, minaral deposits exploiting which is dealed with mineral deposits mathematic-economic model and computer information technology, studied thought numeral analysis, organic relations between these data are found out, thereby intact mine information model are established, so as to achieve the aim to exploit and utilize resource adequately and in reason.Lanping Pb-Zn mines of YunNan province is the biggest Pb-Zn mine of China. However, every produce tache is in aboriginality, so it is necessary for the mine to digitaled. The paper gives a brief introduction on theory and means of orebed digitaled and interrelated mining software in domestic and international. On the basis of systematic analysis and research on Jiayashan ore segment, with the mathematic-economic model software bag developed by our library, via the special software Surpac and Micrmine, on the need of the Lanping Pb-Zn mine, the mathematic-economic model of the deposit has been established in Lanping pb-zn mine Jiayashan ore segment. Correlative important technological and economic guide lines have been analyzed and studied. At last, some fruits have been achieved:(1) For the first time, the mathematic-economic model of Lanpingpb-zn mine has been established , digitated and visualed of all kinds of useful information on ore body have been realized.(2) After the mathematic-economic model of the deposit established, dynamic inquery of data can be carried though, ore body can be determined through dynamic alternative schemes, digital data of the deposit can be sciencly analysised, dealed with, auto drowinged or shortcut calculated with computer, and refered to reserves report forms,Dynamic manage of most manufacture of mine can be realized.(3) After the mathematic-economic model of the deposit established, exterior character, interior construct and interspace change rule of every composition of ore body can be easily observed, resource can be exploitured having a definite object in view so as to achieve the aim of making use of mineral resources in reason.(4) With technology and economy analysis and study on the deposits, the ore segment ore-body are determined in reason and calculated mineral reserves, ptofit and loss evenly geology grade and ore synthesis grade are ascertained, consequently, reduce the waste of resourse and finance, improve the production benefits. |
