摘要

摘要: 在陕西旬阳姚沟铜矿详查工作中，发现勘查区构造发育，地层产状复杂；矿化类型、矿石结构、构造、围岩蚀变呈多样化；矿石质量、矿体形态变异性显著，离散度高，对矿床储量（质量）的估算评价其可信度较低。同时，结合我国现行固体矿产勘查规范对储量估算中存在的对其稳定性和可靠程度无量化分析、评价的问题，提出了采用概率统计原理对矿床储量（质量）进行趋势分析和可靠性（可信度）判断的方法。储量稳定性分析采用储量因子积计算储量稳定性指标β，通过β-n曲线分析矿床储量稳定性，提出储量稳定分析准则；质量稳定性采用矿石品位频数分布p-n曲线分析品位变化趋势，提出质量稳定分析准则；储量（质量）可靠程度判定采用储量因子稳定性指标趋势和矿石品位样本频数分布的交集判定法，用可靠度综合值表示。此外，结合姚沟北矿带实例介绍储量稳定性分析、分组方法，采用归纳法，从特殊到一般，以铜矿为例，寻求判定各类矿种储量（质量）可信度的通用方法。此矿床储量（质量）稳定性趋势分析和可靠度判定方法对各类矿种矿床的评价具有普遍意义，特别适用于金属内生矿床和热液交代矿床。

Abstract: During the general exploration work of Yaogou copper deposit in Xunyang Country, Shaanxi Province, it's found that the assessment of ore deposit's reserves and ore bodies' quality is unreliable, due to the developed faults in the field, complex stratigraphy, diversified types of mineralization,ore fabricand wall rock alteration, high discrete degree of ore quality aswell as ore body shapes.Meanwhile, combing with the current problems about stability and reliabilityof quantitative analysison reserve estimation based on the standards of solid exploration, aprobability statistics method has been proposed to evaluate the trend analysis and reliability of deposit's reserves.Stability index-β is calculated by reserves divisors product,and the stability of deposit's reservesis analyzed by β-n curve of ore grade, and then the criteria of reserves stability analysis has been proposed in this paper.Stability of ore quality is analyzed by the distribution trend of p-n curve,which serves as the analysis criterion of quality stability. The reliability of reserves is show as comprehensive value of reliability, which is judged by intersection between the stable tendency of reserve factors and frequency of ore grade.This paper aims to finding out a widely suitable method to identify the relibility of reserves(quality) by inductive method, which has been applied to Yaogou copper deposit. This method plays an important role in the stable tendency evaluation of deposit's reserve, providing evaluation criteria for stability analysis of mineral deposits with various types, especially for endogenetic metal deposits and hydrothermal metasomatic deposit.
