<p>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:</p>
<p>a) sampling of small or large diameter holes;</p>
<p>b) drill cuttings sampling;</p>
<p>c) open-cut slot sampling;</p>
<p>d) adit, drift or shaft sampling;</p>
<p>e) pillar sampling;</p>
<p>f) channel sampling;</p>
<p>g) strip sampling.</p>
<p>ISO 14180:2017 does not apply to sampling from moving streams in production or any other source of coal that is not <i>in situ</i>.</p>
<p>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.</p>
<p>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.</p>
