Work of the majority of stopes in the Western Donbas is connected with forced coal-cutting with stone, this affects negatively the quality of extracted coal. Because of considerable operational ash content, mines refuse to mine earlier uncovered rather thin layers, which are registered as balance reserve, this leads to reduction of service life of the enterprise. To mine rather thin coal seams it is offered selective mining of coal, as the most real technology which does not demand essential reequipment of stopes. Results of economic calculations confirming its efficiency are resulted in the article.
