Geostatistical coal quality control in longwall mining
2010-3-1 Quality of ROM coal depends not only in-situ quality of coal but also the mining method applied, i.e., dilution of top coal during caving is of major importance. Quality of ROM coal can be estimated by using geostatistical methods prior to actual mining operations. This will certainly facilitate realistic production planning.
