采样是评价矿床的重要手段,它几乎贯穿于地质工作的各个阶段,消耗着大量的资金和人力.因此,在尽可能保证正确评价矿床的前提下,选择经济的,即较小的采样规格和较少的采样数量,是一个值得研究的问题. 确定矿床的采样规格和数量,以往多用类比法,也有的通过采样试验来选择,但多停留在定性的水准上,因此进行定量研究是必要的. 采样规格问题的研究可归纳为:当采样个数一定时,保证在样品平均值不超过最大允许误差的前
Sampling is an important means of evaluating a deposit and it runs through almost every stage of geological work and consumes a great deal of capital and manpower.So as far as possible to ensure the correct evaluation of the deposit under the premise of choosing an economical, ie smaller sample size and Less sample size is a problem worth investigating.It is necessary to determine the size and number of samples in the deposit, the conventional multiple analogy method, and some sampling tests to choose from but stay at the qualitative level, so it is necessary to do quantitative research The study of sampling specifications can be summarized as follows: When the number of samples is constant, ensure that the average of the samples does not exceed the maximum allowable error
