河南某铝土矿矿体形态研究

简述了河南某铝土矿矿体有层状、溶斗状和透镜状三种基本形态及其成因。结合该铝土矿勘探资料,研究了该矿区矿体形态类型,统计不同形态矿体的钻孔工程数量比例,给出层状和溶斗状矿体资源量的计算公式,用VB编写计算程序,可快速计算该矿区铝土矿资源量。结果表明,溶斗状矿体数量虽少,但却构成了矿区资源量的重要部分。

Shapes of Bauxite Deposits in a Mining Area of Henan

Three main kinds of bauxite bodies(beded,lensoid and karst funnel shape) in one bauxite deposits in Henan province and its causes of formation are stated in this paper.Based on a comprehensive analysis of exploration data on the mining area,the shapes of bauxite deposits in this mining area are studied.The ratio of drilling with different forms of the orebody is worked out,a formula and a corresponding computer program prepared by VB are given,which can calculate the amount of bauxite deposits simply bedded or karst funnel shape.The results show that the number of orebody like karst funnel shape is less,but it is an important part of the resources in the mining area.
