The classification of resources and reserves of coal in Indonesia is based on the Indonesian National Standard (SNI), which is published by the Agency National Standardization. SNI is an entitled Guideline for reporting resources and reserves coal (SNI 5015 2011 years). The current classification of the geological conditions in the SNI 5015 in 2011 is still a qualitative description, but in the future, the study of geological conditions of coal classification should already be using a combination of quantitative and qualitative methods. Therefore, the determination of the input parameters of sedimentation, tectonics and coal quality should be planned for as many as possible to get quantitative data rather than qualitative descriptions. The process of classifying geological conditions will be largely determined by geological knowledge and methods of quantifying the spatial relationship used in geostatistical approach. Merging the two of the above will provide a more acceptable in terms of geological knowledge and in terms of geostatistical approach.
