Guidelines on state-of-the-art aspects of drilling and sampling coal. Can be modified as necessary to fit your specific needs (for example, you can use them to prepare your own field manual to standardize exploration activities). Chapters include: drilling equipment; • geophysical logging; • description of coal and rocks; • sampling of coal cores; • laboratory analysis of coal and rock drill core samples; • and evaluation of core data.

Also serves as a reference document for those who use the core sampling ASTM standard Practice for Collection of Coal Samples from Core (D 5192) (included in the Appendix).
