ISO 14180:2023 - Coal - Guidance on the sampling of coal seams (Overview)
ISO 14180:2023 provides guidance for taking representative samples directly from coal seams in situ. Intended for exploration areas, tenements and operating underground or open-cut mines, the third edition (2023) describes safe, traceable methods to collect both small and bulk samples and to prepare them for transport and laboratory analysis. This standard is focused on in‑place coal seam sampling and explicitly excludes sampling from moving production streams or other non‑in situ sources.
Key topics and technical requirements
-
Sampling methods covered - Detailed guidance for:
- Core sampling (small- and large-diameter cores; common diameters noted as 50 mm–200 mm)
- Drill cuttings (chip) sampling
- Open‑cut slot sampling
- Adit, drift or shaft sampling
- Pillar sampling and block recovery
- Channel sampling (vertical channels through the seam)
- Strip sampling (smaller cross-section channel-like samples)
-
Site selection and preparation - Guidance on choosing representative sampling locations, obtaining permissions from mine managers or tenement owners, and coordinating multidisciplinary teams (geologists, mining engineers, safety officers, lab staff).
-
Sample handling and documentation - Procedures for core recovery, handling, identification, bagging and boxing, labelling, and transport. Annex A provides an example channel sample record form to standardize data capture.
-
Quality and representativity - Emphasis on collecting representative samples to characterize lateral and vertical variation of seam lithotypes, plies and inorganic layers; recommendations for multiple samples where seams are heterogeneous.
-
Safety and governance - Strong recommendation for a pre‑sampling risk analysis and compliance with site safety procedures.
-
Related technical notes - References to sample mass determination methods (ISO 13909 and ISO 18283) and vocabulary (ISO 1213-2).
Practical applications and users
ISO 14180:2023 is essential for professionals involved in coal resource evaluation and quality assessment, including:
- Exploration geologists and field samplers
- Mining and geotechnical engineers
- Mine operators and environmental/safety officers
- Coal quality laboratories and sample preparation facilities
- Regulators and consultants preparing mine feasibility, reserve and compliance reports
Use cases include resource definition drilling programs, seam characterization for mine planning, pilot wash and combustion test sample collection, and baseline environmental or regulatory sampling.
