本文论述了判定金属矿床勘探类型与合理勘探网度以及对矿床勘探程度要求等问题,提出对按现行规范需用坑道在深部探求高级储量的金属矿床、呈囊状矿体群产出埋藏较深的铬矿床、品位很高分布极不均匀的中小型石英脉金矿床,应适当降低勘探程度,在初勘或详查结束后,就可研究设计探采结合井或平窿。这样可节省投资,并能加快矿山建设速度。文章重点论述了圈定矿体的原则和方法,简要评述了传统法、克里格法、杨赤中滤波推估法等储量计算法的应用条件及其存在的问题,并推荐作者建立的椭圆抛物面体用于计算囊状矿体外推部分的几何模型和单工程三维金属量分布密度模型,用于处理特高品位,计算矿块平均品位。
This paper discusses the problems of determining the types of exploration and the reasonable exploration network of the metal deposits and the requirements for the degree of exploration of the deposits. The paper proposes that the metal deposits required to be explored into the deep reservoirs according to the current regulations should be buried deep Of chromium deposits, high-grade distribution of very uneven small and medium-sized quartz veins gold deposits, should be appropriate to reduce the degree of exploration, exploration or detailed investigation at the end of the study can be designed to explore the combination of wells or holes. This saves investment and speeds up mine construction. This paper focuses on the principles and methods of delineating ore bodies, and briefly reviews the application conditions and existing problems of the traditional methods, Kriging method, Yang Chih-zhong filtering estimation method and so on. It also recommends that the author establish the elliptical paraboloid In the calculation of extrapolation of the cystic ore body geometry model and single-dimensional three-dimensional metal density distribution model for processing extra-high grade, calculate the average grade of ore.
