| 摘 要： | 通过对露天矿爆破后爆堆表面粒度分布的直观描述,提出了在爆堆表面以粒度分布均匀程度为标志的分区摄影抽样法,并根据数理统计规律推导出了与爆破规模、可信程度和误差范围有关的抽样数公式,并进行了验证。

| Abstract: | By way of the direct illustration of the size distribution on the surface of the muckpile of the open- pit mine, We, based on the well-distrbuted degree of the size, put forward group shooting sample method on the muckpile surface; and reasoned out the formula of calculation sample numbers in relation to blast scale, believable degree and range according to the rule of mathematical statistics, and they were tested and verified. |
