PROJECT ESSENCE: Extraction of coal and rock mass is made separately in two or one passage of combine. Bedding of rock mass in mined out area is made simultaneously with its extraction.  The technology is performed at different systems of development: pillar, entire and combined. 
 
TECHNOLOGICAL SCHEME OF SELECTIVE COAL EXTRACTION:
 
IN TWO PASSES OF COMBINE
IN TWO PASSES OF COMBINE 
 
IN ONE PASS OF COMBINE
IN ONE PASS OF COMBINE
 
APPLICATION AREA: The subject of technology implementation is seams, related to off-balance according to the rock mass thickness or the development of which are impossible without shortage of the side rocks (about 60 – 70% of Ukrainian seams). Checking technology and pilot sample of the complex are assumed in the mines of Western Donbass of DTEK Company.
