Abstract (en)
[origin: WO2005071226A1] The invention relates to a method for extracting a mine gas even outside of an action or limiting angle (5) ensuring environmental protection. The inventive method consists in perpendicularly drilling three bore holes (9) in a rock (1) and, afterwards in deflecting and purposefully orienting them in such a way that gas circulation paths mainly formed or formable in the area between the limiting angles (5, 6) are drilled approximately in a vertical direction to a diagonal. Said invention makes it possible to reliably extract a migrated mine gas and use it.
