摘　　要：寨上金矿床现处于普查阶段,开展工作的程度较低,按照《岩金矿地质勘查规范》的要求,在勘查工作时,应尽量使用计算机信息处理技术并提倡使用多种方法估算资源量。基于上述原因,在编制寨上金矿床北段普查地质报告的过程中,使用了SD储量通和Micromine kantan3D软件系统审核了该地质块段法估算的资源量,计算了12条矿脉的资源量。文章主要通过以下5个方面进行探讨:①利用软件的校验功能,发现数据错误,审核基础数据;②通过矿体三维模型的建立,审核矿体圈定连接的合理性;③应用Micromine kantan3D软件系统的封闭多面体估算法审核矿体体积;④应用Micromine kantan3D软件系统的距离反比法审核矿体品位和金属量;⑤应用SD储量通软件审核矿体金属量和矿石量。在地质勘查工作中通过以上多种资源量计算方法相互配合,确保了资源量计算结果的真实可靠,并就资源量估算方法选择和如何做好人机交互工作进行了说明。In Zhaishang gold deposit,the standard of geological exploration is in the reconnaissance survey stage, with less work, according to the requirements of ＂standard of rock gold mine geological exploration＂ , it should be tried to use the computer information processing technology and advocate using a variety of methods to estimate resources in exploration work.Based on the above mentioned ,on the preparation of the survey geological report for the northern Zhaishang gold deposit,use SD and Mieromine kantan3D software system to review the estimating the resource by geological block,and calculate the resource of 12 veins.This paper mainly through the following five aspects to discuss ： @Using the software validation function,found data errors and reviewing basic data ; @Through the establishment of 3D model check the rationality of orebody connection; @Using closed polyhedral estimation method of Micromine kantan3D software system audit orebody volume; @Using Inverse distance method of the Micromine Kantan3D to evaluate both the quality of the ore and the to tala mount of metal ; @using the SD system to examine the amount of metal and ore.In conclusion, comprehensively using a variety of methods to calculate the quantity of resource in the geological exploration work,it ensures that the resouree of the calculation results is true and correct.Additionally,what is also presented in this article is discussion on choosing effective method in resource calculation and choosing efficient way in implementing collaborative work between human and computer.
