摘要
地质块段法是煤炭资源/储量估算中最常用和最重要的方法。块段的具体划分方法在相关规范和规定中并无明确的具体规定,而块段的划分方法不同,估算的资源/储量结果亦不同。结合生产实际,通过实例应用,定量分析了地质块段不同划分方法所产生的误差,并对地质块段不同划分方法进行了定量评价。经过分析和确定误差的影响因素,提出了最佳块段划分的具体原则与方法,对提高煤田勘查中资源/储量估算的准确度具有现实意义。
The geological block method is the most important and commonly used method in coal resources/ reserves estimation. However, the geological block does not have concrete definition in related norms and regulations. Different method of block division gives different results in resources/reserves estimation. According to the actual production, this paper analyses quantitatively the errors of different division methods, and conducts quantitative evaluations. Through analyses and determination of the influencing factors of errors, the best division method has been put forward, which has important realistic significance for the improvement of the accuracy of coal resources/reserves estimation in coal field investigation.
