Changes in technology of mechanical coal processing in Poland were characterized in the paper. An attention was drawn to the present requirements of power industry, coke industry and export as regards the quality of coal, which conditions the preset state of coal processing technology. Directions of coal processing modernization which are a reaction for increasing press from ecology, economy and work safety were presented. The advance in coal processing technology, observed in last decades, includes main washing operations and concerns technological solutions of machines and equipment as well as chemical agents that support the process. Many of that solutions were implemented in modernization projects in mechanical coal processing in the Polish hard coal mines, in which Central Mining Institute is involved from many years.
