Evaluation and distribution characteristics of green coal resources in Shanxi province

The development of coal industry of China is facing the opportunities and challenges of the “energy revolution”, the concept of green coal resources has emerged in the context.Based on coal resource and regional coal quality characteristics of Shanxi province, and adhering to the development concept of “innovation, coordination, green, openness, and sharing”, focusing on the development and utilization of the three major coal bases in Shanxi province, a four-dimensional green coal resource evaluation system has been constructed that integrates coal quality, coal process performance, coal seam storage conditions, mining technical conditions and ecological conditions.According to the results of previous coal exploration, the paper systematically evaluated the distribution characteristics of green coal resources of Shanxi province, through the overlay analysis of the evaluation factor mapping and the review of related technical conditions.It shows that Shanxi province green coal resources are generally limited by coal seam depth, ash content of Shanxi formation and sulfur content of Taiyuan formation, and partially restricted by the water of Ordovician limestones in coal seam floor.The amount of green coal resources in Shanxi province is not rich.The green coal resources are about 79.11 billion tons, of which about 59.05 billion tons are not occupied by coal mines, accounting for only 20% of the total coal resources.Green coal resources are mainly used for coking coal and chemical coal, while relatively less used for green power.
