Standard Practice for Statistical Modeling of Uncertainty in Assessment of Inplace Coal Resources
|Publication Date:||1 November 2018|
This practice covers a procedure for quantitatively determining in-place tonnage uncertainty in a coal resource assessment. The practice uses a database on coal occurrence and applies geostatistical methods to model the uncertainty associated with a tonnage estimated for one or more coal seams. The practice includes instruction for the preparation of results in graphical form.
This document does not include a detailed presentation of the basic theory behind the formulation of the standard, which can be found in numerous publications, with a selection being given in the references (1-3).2
This practice should be used in conjunction with professional judgment of the many unique aspects of a coal deposit.
