This Standard sets out recommended practices for the technical evaluation of a higher rank coal deposit, principally using borehole techniques. It defines the various stages that comprise an exploration project, describes drilling equipment and methods, and makes specific recommendations concerning procedures that should be adopted in the logging, testing and analysis of a bore core. This Standard recommends procedures for the technical evaluation of a coal deposit within the context of the entire exploration program. It provides a reference framework that will promote-(a) greater appreciation, within an exploration team, of the individual needs of its members; and(b) a uniformity of approach, from team to team, to the technology of coal exploration.A bibliography of reference texts appropriate to the various clauses of the Standard is given in Appendix A.
