Abstract: Jindong coal base is an important production area of high-quality anthracite in China,which is one of the 14 coal bases planned and constructed by the state. Based on the data of "National large coal base exploitation potential research" of National Energy Administration, this paper calculates the exploitation intensity coefficient of Jindong coal base is 0.5, the capacity utilization rate is 82%, and the coal recovery rate is 52.4%. According to the calculation results, the exploitation situation of Jindong coal base is analyzed and predicted: the exploitation intensity of the Jindong coal base should be appropriately reduced; the coal recovery rate will be increased to a certain extent; the production capacity and coal production of the Jindong coal base are expected to decline, the scientific production capacity of the Jindong coal base is estimated to be 350 million t/a and the output is about 280 million t/a. It is of great significance to the scientific mining and sustainable exploitation of Jindong coal base.
