非金属矿产勘查中资源评价方法与数据质量控制技术探讨

Exploration of Resource Evaluation Methods and Data Quality Control Techniques in Non Metallic Mineral Exploration

摘要: 饰面石材以及多种非金属矿产在我国分布广泛、储量充足，是建材行业稳步发展、提质增效的重要保障。在矿山资源开发利用中，需对勘查成果进行评估分析，因此，要求选用适宜的资源评价方法，并加强数据质量控制。本文以贵州安龙县高坡饰面石材勘查区为例，整理非金属矿产勘查里资源评价的常用方法，搭建从测量、地质填图、水工环调查，到探矿工程、采样测试都能覆盖的数据质量控制体系。根据现场应用分析，高坡勘查区矿体规模大、产状平稳，勘查难度不高，用垂直断面法计算、方格网法核对，两种结果相对误差只有4%，可信度较强；借助分级精度管理、规范采样测试流程、统一工程施工要求，勘查数据从采集到整理达到规范标准。

Abstract: Decorative stone and various non-metallic minerals are widely distributed and have sufficient reserves in China, which is an important guarantee for the steady development, quality and efficiency improvement of the building materials industry. In the development and utilization of mining resources, it is necessary to evaluate and analyze the exploration results. Therefore, it is required to select appropriate resource evaluation methods and strengthen data quality control. This article takes the Gaopo Decorative Stone Exploration Area in Anlong County, Guizhou Province as an example to summarize the commonly used methods for resource evaluation in non-metallic mineral exploration, and establish a data quality control system that covers measurement, geological mapping, hydraulic and environmental investigation, exploration engineering, sampling and testing. According to on-site application analysis, the ore body in the high slope exploration area is large in scale, stable in attitude, and not difficult to explore. Using the vertical section method for calculation and the grid method for verification, the relative error between the two results is only 4%, indicating strong credibility; With the help of graded accuracy management, standardized sampling and testing processes, and unified engineering construction requirements, survey data is collected and organized to meet standardized standards.
