Download or read book A Standardized Coal Resource/reserve Reporting System for Canada written by John D. Hughes and published by Geological Survey of Canada. This book was released on 1989 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discussion of definitions, concepts and parameters used to determine coal resource and reserve quantities, as well as providing a framework to facilitate consistent categorization of coal quantities found within various depositional and tectonic regimes in Canada. Coal deposits, or portions thereof, are first categorized in terms of their geological complexity (geology type) and probable recovery method (deposit type). Methods for determining quantification parameters including seam thickness, areal extent and bulk density are outlined for each geology/deposit category. Within each geology/deposit category, coal resources are further divided, based on their assurance of existence, into measured, indicated, inferred, and speculative subdivisions, and according to their feasibility of exploitation, into immediate and future interest subdivisions. Coal reserves within each geology/deposit cateogry are subdivided according to whether they are within or outside active mining areas, and may be reported on inplace, recoverable and saleable bases.
