标准范围

本文件为从地下煤层取样的方法提供了指导，无论是从勘探区或矿权区，还是从地下或露天矿中取样。描述了以下方法:A）？小直径或大直径孔的取样；b）？钻屑取样；c）？开槽取样；d）？平硐、巷道或竖井取样；e）？柱状取样；(f)？信道采样；(g)？条带取样。本文件不适用于从生产中的流动溪流或任何其他非原位煤源中取样。对采样点的选择和准备提出了建议，并描述了采集小样本和散装样本以及准备运输样本的方法。笔记？附件？A给出了一个通道样本记录表的例子，可以用来记录采样和其他相关数据，以及ISO？13909和ISO？18283描述了如何在各种标称顶部尺寸下确定代表性样品的质量。

This document provides guidance on methods for taking samples from coal seams in the ground, whether from exploration areas or tenements, or from operating underground or open-cut mines. The following methods are described:

a)       sampling of small- or large-diameter holes;

b)       drill cuttings sampling;

c)        open-cut slot sampling;

d)       adit, drift or shaft sampling;

e)       pillar sampling;

f)         channel sampling;

g)       strip sampling.

This document does not apply to sampling from moving streams in production or any other source of coal that is not in situ.

Recommendations are made for selection and preparation of the sampling site, and methods are described for taking both small and bulk samples and for preparing the samples for transport.

NOTE            Annex A gives an example of a channel sample record form that can be used to record sampling and other relevant data, and ISO 13909 and ISO 18283 describe how to determine the mass of a representative sample at various nominal top sizes.
