In 1962, geostatistics was first established by Professor G.Matheron, a famous French scholar. Geostatistics is a newly developed edged cross subject , it is meant to solve the space structure and random of ore-despits data, its purpose is mainly to solve problems about various reserve estimation and estimate reserve estimation's error margin in exploration ,mine exploitaltion and mine design.With the development and use of the computer technique, geostatistics is developed from estimating to imitate , from the initial stage of two dimensions imitate to many dimensions emulation, from imitating the static stateto imitating the dynamic state.We have analyzed three dimensions static state of the stereoscopic spaceses to estimate from two flat surfaces of dimensions in the earlier periods, and carried on the research in the fore basic virtues and maybe in the dynamic state of the higher than four dimensions space to estimate and imitate today in the timespace area.Recently we have known a ground of resources quantity concentration in the Wandong mountain section currently, and the No.52 mineral body of the Wandong mountain section have 60% of the total resources quantity, which is biggest mineral body of the Beiya gold district. The geology characteristic and the mineral regulation of the No.52 mineral body of the Wandong mountain section is the representative of the Beiya gold area. On the basis of the database of the diagraph and the mineral body exploration foundation, the establishment is since the economic model of database, mathematics of the geology data of the No.52 mineral body of the the Beiya gold district'Wandong mountain section, the numeral that carrys out an the No.52 mineralbod of the Beiya gold district'Wandong mountain section turn and the three dimensions are stereoscopic and can see to turn, including the geography, mineral body, lithology, faultage and mining for the models,engineering and the Earth physics...etc. Carry on the analysis to the each model, beat to descend the solid foundation for the production performance that build up seeks the exploration accuracy and the exaltation mineral mountain.
