摘要
///This paper presents the geological characteristics of the gold-vanadium deposit in Xiajiadian,Shanyang County,Shanxi Province,where the ore body lies in the strata and fault structure associated with the Cambrian System.Based on previous geological survey data of the deposit,the authors have built the deposit database,surficial model of the mining area,orebody model and block model of grades by means of Surpac software.The models show vividly the topography and landform in the mining region as well as the location and morphology of the orebody.The block model of grades,based on the common Kriging method,simply and clearly displays locations and grades of orebodies.Some orebodies are divided into basial blocks for estimation of gold and viadium resource reserve.The result suggests that the smaller the divided basical block units,the more accurate the estimation of orebody resources is.Compared with the resultant ore resources with that by the traditional geological block method,the reserve estimation based on the Surpac software is more reliable and accurate.
