Definition
|
Outburst has been defined as a spontaneous
ejection of gas and coal from the solid face, where the gas is
a mixture of methane and carbon dioxide. This definition is questioned
in the use of the term "spontaneous" as this suggests an outburst
occurs without triggering, when an outburst can be provoked with
the use of explosives or during the cutting of coal. Thus, outbursts
have also been defined as a phenomenon characterised by ejection
from the solid face into the mine as a mixture of broken rock
and gas.
