摘要

由于矿产资源数据具有动态性和多维性,使得矿产资源利用现状的信息难以准确反映实际利用情况,进而导致矿产资源量预测结果不准确。为此,本研究提出基于矿产资源利用现状动态信息的储量预测方法,对矿产资源勘查数据进行格式转换和编码处理,并将其输入到GIS系统中,利用GIS技术将数据划分为空间数据和属性数据,由此确立资源利用现状管理体系,引入全关系型数据库实现对矿产资源利用现状的管理。然后,结合地质三维模型计算成矿有利度,从而圈定成矿靶区,以此为依据,构建品位—吨位模型,并采用统计取样理论预测矿区资源储量。实验结果表明,应用该方法预测的矿产储量与实际储量相一致,说明该方法预测准确度相对较高。

Abstract：

Due to the dynamic and multidimensional properties of mineral resource data, the information on the utilization status of mineral resources fails to accurately reflect the actual utilization status of mineral resources, leading to inaccurate predictions of mineral resources. Therefore, this study proposed a reserve prediction method based on the dynamic information on the utilization status of mineral resources. The exploration data of mineral resources, subjected to format conversion and encoding, were input into the geographic information system (GIS). They were categorized by the GIS into spatial and attribute data, thereby establishing a resource utilization status management system. A fully relational database was introduced to manage the utilization status of mineral resources. A 3D geological model was employed to calculate the ore-forming favorability and delineate the mineralization target area. Based on this, a grade-tonnage model was constructed. Finally, the statistical sampling theory was applied to predict the resource reserves in the mining area. The experimental results demonstrate that the mineral reserves predicted using the proposed method aligned with the actual reserves, indicating a relatively high prediction accuracy.
