Dnieprovsky lignite basin, situated in central part of Ukraine over the area of about 400 km2, contains more than 150 deposits. About 55 deposits have industrial significance. Their reserves are 2.4 billion tons. Seams and lenses of coaly clays and sands overlay the coal series and occur between coal packets. The coaly clays are classified into this category because their ash content exceeds 40%. Our investigations show that coaly rocks are similar to lignite in composition and properties. They have ash content from 40% up to 60%, the same elementary composition of organic matter. As well as bitumen and humic acids yield. It has been established that coaly rocks can be used as energy and chemical raw material, the basis of good carbon sorbents with high adsorptional capacitance. The recommendation of coaly rocks for mining and processing is difficult because of lack of information in geological reports on their quantity, composition and properties, as they are considered as host rocks but not as mineral resources. If the usable coal limit was accepted at 50% of ash content, the coal reserves of some deposits would have increased 1.5-2 times.
