Optimisation of nitrogen injection for inertisation of longwall
01.07.2001As the roof is mainly hard rock, goaf is highly porous and important air leakage in the goaf acts against natural methane inerting. Due to this reason, HBL are using nitrogen for inertization of the goaf in order to avoid spontaneous combustion of remaining coal in association with classical methods in order to limit air leakage.

Recent developments in coal mine inertisation in Australia
During 1997 two different types of coal mine inertisation equipment were trialed in separate underground coal mines in Queensland. In April 1997 tests of the Polish developed GAG-3A inert gas generator were carried out at the Collinsville No 2 Coal Mine.

Spontaneous Combustion
However in coal mines, coals spoken of as being liable to spontaneous combustion are those coals which will develop to an open fire under specific conditions. Many seams will not reach this point. When spontaneous combustion occurs, there is an initial stage where the temperature is rising but no burning in the normal sense is taking place. This stage is known as a heating.
