摘要
地质块段法是煤炭储量计算的常用方法。原精度评定公式的前提是指标变化完全随机,这不符合实际。本文考虑了煤矿床指标变化的相关性,并以此推导出了评定储量计算精度的新公式。新公式克服了原方法中的缺点,它适用面广、结果可靠。
The formula of geological blocking often used to estimate coal reserve is defective in evaluation of precision because the premise to use its formula is that the parameters of coal deposite must be at entire random, which is not conformable to reality. Considering the correlation of the para- meters variation, a new formula to evaluate the precision in estimation of coal reserve is deduced. It can overcome the shortcomings of the former formula.Its adaptability is wider and the result is more reliable.
