A number of physical-mechanical and physical-chemical characteristics of coal preparation and processing waste samples have been determined. In a number of physical and mechanical properties investigated: moisture content, bulk density, grain composition and coarseness modulus, fineness of grinding and hydraulic activity of ashes.
In a number of physico-chemical properties investigated: solubility in water, leachability in nitric and sulfuric acids, ash content; X-ray phase analysis of samples of coal waste. On the basis of certain characteristics, a processing method will be developed in the future
