Determining Commercial Feasibility of Coal Deposits
Feb 03 2020
ASTM International has approved a new standard that could help mining companies, regulatory bodies, and geological surveys to assess coal tonnage-in-place. Assessment of coal tonnage-in-place is a fundamental factor in evaluating the commercial feasibility of a coal deposit. ASTM’s committee on coal and coke (D05) developed the standard (D8215).
The new standard provides a geostatistical methodology to calculate the uncertainty of an in-place, coal resource estimate, both at the deposit and block level. The original methodology was developed by the U.S. Geological Survey.
Luppens notes that standard allows statistical analysis to be presented according to widely-accepted conventions, such as percentiles and confidence intervals. Additionally, the results of an uncertainty determination can provide important input into an overall risk analysis assessing the commercial feasibility of a coal deposit.
