This International Standard provides guidance on methods for taking samples from coal seams in the ground, whether from exploration tenements, or from operating underground or open-cut mines. The following methods are described:
a) bore core sampling;
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 International Standard 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 sample record form that may be used to record sampling and other relevant data, and ISO 9411-1 [1] describes how to determine the mass of a representative sample at various nominal top sizes.
