Abstract

Sposób udostępniania metanu ze zrobów górniczych, charakteryzuje się tym, że w trakcie przechodzenia przez zroby górnicze i w strefie górotworu spękanego na skutek dokonanej eksploatacji, otwór eksploatacyjny wykonuje się z wykorzystaniem metody udarowo-obrotowej z dolnym młotkiem (3) i świdrem (3a), przy równoczesnym zapuszczaniu kolumny rur okładzinowych (2) wyposażonych w but z koronką (5) w taki sposób, aby świder (3a) wyprzedzał but kolumny rur okładzinowych (2) o ustaloną odległość.The method of making methane available from the goafs is characterized by the fact that while passing through the goafs and in the area of the fractured rock mass as a result of exploitation, the mining borehole is made using the impact-rotary method with the lower hammer (3) and drill (3a), with simultaneous lowering of a casing column (2) equipped with a casing shoe (5) in such a way that the drill bit (3a) is ahead of the casing shoe (2) by a predetermined distance.
