ISO 14180:2017提供了从地下煤层中采集样本的方法指南，无论是从勘探区或物业单位，还是从地下或露天开采的煤矿中采集样本。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） 条状取样。 ISO 14180:2017不适用于从生产中的移动溪流或任何其他非原位煤源进行的采样。 对采样地点的选择和准备提出了建议，并描述了小样本和散装样本的采集方法，以及运输样本的准备方法。 注:附录A给出了可用于记录采样和其他相关数据的通道样本记录表示例，ISO 13909或ISO 18283描述了如何确定各种标称顶部尺寸下代表性样本的质量。

ISO 14180:2017 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. ISO 14180:2017 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 or ISO 18283 describes how to determine the mass of a representative sample at various nominal top sizes.
