Special features of identification of process groups in coal grades when estimating reserves
The norms and specifications have been reviewed that regulate the identification of process groups and the types of coal and ore have been compared in terms of natural and industrial types. It has been determined that the difference of industrial (process) types of ore and coal is conditioned by the degree of processing to obtain finished product, while the guidelines of the State Committee on Reserves lack the qualitative parameters for the conditions to identify the process types of coal. It is suggested, that the reserves of coking coal should be identified as carbon forming (premium) and process (valuable), while the thermal coal should be identified as energy-technological and fuel
