According to the first stage results: the brown coal mining parameters for the further stabilization of its quality have been determined; the assessment of the raw material base of the Dniprovsky brown coal basin and the North-West Donbas deposits has been performed; the quality indicators of brown coal mining have been set; the technologies for the complex development of the Novo-Dmytrovsky deposit were substantiated; the technology process for brown coal processing by options, including preparatory (crushing), thermal vacuum drying, heat treatment and enrichment (separation), have been worked out; the world practice of the brown coal processing has been given; brown coal crushing and thermal vacuum drying parameters have been defined; the brown coal heat treatment parameters have been set; the brown coal enrichment (separation) parameters have been defined; the obtained parameters of crushing, thermal vacuum drying, heat treatment and enrichment (separation) of the brown coal have been systematized.
According to the second stage results: the expediency of agglomeration the products and determining their types have been substantiated; the brown coal enrichment technology for obtaining a fuel with high energy properties has been developed which is confirmed by appropriate regulations; quality characteristics of the solid fuel after its modification in the thermal vacuum installation and its enrichment have been set.
According to the third stage results: the limit overburden coefficient of the brown coal deposits has been calculated using the method of financial and mathematical averaged costs and the enrichment technology has been developed; the test batch of high-calorie solid fuel with high energy properties has been produced, which is confirmed by an appropriate Act.
