METHOD FOR DEGASSING ROCK MASSIF OF MINE WITH USE OF SCREW COMPRESSOR UNITS

摘要

Method for degassing rock massif through extraction of natural gas from rock seams through wells with control of concentration and debit of gas in those, with supplying it to collector systems and discharge of gas from those to surface is in fact that natural gas from wells collected is supplied to suction units of screw compressors, with gas compression to needed pressure, it is supplied to common collection collector from which gas is directed to liquid separator and after that with vacuum pump one pumps it out to surface.
