The Research Of Mathematical And Economical Model Of No.100 Ore-body In GaoFeng Tin-Mine,GuangXi

No.100 ore-body is a poly-metallic ore-body which abundance with Sn and Pb Zn. Sb A in GaoFeng Tin-Mine, GuangXi. The new techniques of ccimputer, geostatistics theory and methods are firstly apply to establish the mathematics-economic model of No.100 ore-body in this paper, in order to realize the dynamic management of mining production and enough exploit of mineral resources. The main results are listed as follow: The original database of No.100 ore-body has been established. There are about 200 prospecting projects including, their three dimensionality coordinates, 3200 samples and 10500 analyzed data of Sn Pb. Zn Sb and Ag in the database. Fundamental statistical analysis shows that the values of Sn Pb Zn. Sb and Ag are logarithmic and normal distributed. The database can be used by the mining dynamic management whenever necessary. The variograni of No.100 ore-body in three directions have been calculated, and the variogram curves were formulated. All these curves are leap type. The mathematical models of grade variability of Sn. Pb.. Zn.. Sb and Ag have been established respectively, the structural analysis of No.100 ore-body indicates the ore-body varies band anisotropically. Cross testing and verifying shows that the estimation error is in the allowed range. Aiming at that No.100 ore-body changes greatly in morphological characteristics, the new method to respectively estimate depending on the occurrence is applied, litho logy model of No.100 ore-body is established. And the lithology value is estimated in blocks of one model. By means of Kriging, the grade model of No.100 ore-body is established, the grade values are estimated by the unit of 2m X 2m X 2m cube meters in volume, the reserves of Sn. Pb Zn.. Sb and Ag are calculated by ten different cut-off grades. The mineral mode of Cassiterite, Jamesonite, Marmatite, Arsenopyrite, Pyrite and Magnetic Pyrites are established on the basis of the the grade model of No.100 ore-body. The maps of sections and planes are plotted and the mineral deposit is calculated. Which are the basis .for the synthetic and rational exploitation of No.100 ore-body. The multianalysis of the Sn. Pb.Zn. Sb .. Ag. As. Cd.. Fe and In are done to find the relation of the elements.
