Abstract

Emission of firedamp in a colliery with high reported incidence of the gas has been investigated. Methane make up along the ventilation path, borehole emission rates and residual methane content of the coal were measured and their roles in the calculation o gas production par unit tonne of coal raised as well as in studying distribution of the gas in the seam examined. The studies indicate that in a highly gassy mine, reliable figures on gas evolved per tonne of coal cannot be obtained from investigation carried out during development period when production is low. Migration of firedamp to the top of the dome i.e. in the anticlinal part of the seam has been observed. It has also been found that emission rates from freshly exposed surface fall rather rapidly before a near steady state is arrived.
