The Calculation Method Research of Resources Reserves of Manganese Ore in Daotuo Songtao County Guizhou Province

贵州松桃道坨锰矿床是新发现的超大型全隐伏矿床,资源储量位居全国首位。为降低资源储量计算难度、提高精度,引入三维地质模拟技术,结合现代地质统计学法,构建数字化三维模型,建立真三维环境下深部矿产资源储量计算方法流程。该方法直观形象地表达矿体空间分布特征,以"可视"的方式科学合理地划分矿体块段及储量类别;并对比分析传统几何法,实现道坨锰矿资源储量分类计算。研究结果表明:该方法计算结果科学合理、高效准确,可用于对比验证传统几何方法;该方法具有推广性和适用性,可推广应用到深部矿产资源储量计算,尤其适用于贵州矿产资源深部找矿现状。

A super-large concealed manganese deposit is discovered in Daotuo Songtao county Guizhou province,whose resource reservation ranks first in China. This paper uses 3D geological modeling technique to build digital 3D model in order to reduce the difficulty and improve precision of reserves calculation. This paper,combined with the modem geological statistics method,established the method and process of deep mineral resources reserves in true 3D environment. The method intuitively reflects the spatial distribution characteristics of ore body,and visually divides ore body block and reserves into different classification scientifically and reasonably,then realizes the comparative analysis of traditional geometry method. Finally,this paper implements calculation and classification of Daotuo＇s manganese ore resources reserves. The results show that calculated results the method using is scientific and rational,efficient,accurate,and can be used for verification of traditional geometry method,and that the method has generalization and applicability,and can be applied to the deep mineral resources reserves calculation,especially to explore deep mineral resources in Guizhou.
