Modeling of gas circulation in the goaf of retreat faces/

, 1997
French coal mines are deep, gassy and prone to spontaneous combustion. The main technique used for mining at Houilleres du Bassin de Lorraine (HBL) consists in retreat faces, mainly as a consequence of strata pressure at a current depth of 1000-1200 m.
