Abstract:

High quality grade evaluation of coal resources provides the basis for the coal industry planning and the reasonable exploration and utilization of coal resources. Fully referring the predecessor's research achievements of coal quality evaluation, based on the coal quality data obtained by the coal geological exploration, the index system and the index division scheme of the coal resources high quality grade evaluation were established for coking coal, steam coal and chemical anthracite in Shanxi according to new current standards and specifications. Each index weight was determined using the combination methods of the distance maximization and the expert scoring. Based on the grey relation analysis, the dynamic mathematical models of the coal resources quality grade evaluation were established. Using the models, the high quality grade evaluation of coal resources was carried out for three exploration areas in Shanxi.

Key words: Shanxi, Grey Relation Analysis, Coal Resources, High Quality Grade Evaluation
