While working at Vane Tempest colliery, Co Durham, one of my weekly
tasks was to take gas samples from a spontaneous combustion fire in the goaf
in the Low Main Seam. This fire had been burning since the 1960's and a
regular analysis was performed on the samples to check for carbon monoxide
and oxygen to give an indication of the condition of the fire.
The air temperature in the roadways around the area of the fire was
always very high with a wet and dry bulb reading of around 22 C and 28 C.
The goaf had been sealed to prevent the oxygen entering but at one
point in the 70's, when it was considered safe, the stopping were opened,
but the fire rekindled and the goaf had to be resealed. The goaf remained
seal and sampling was resumed until the closure of the colliery in 1992.
Is it still burning ? Perhaps the rising minewater in the area has
extinguished it.

Subject: Spontanious conbustion in coal mining tips
Hi All,
I have been reading an archaeological report discussing the
vitrification of
the interior of the ramparts of some IA hill forts. At one point
some coal
miners are quoted as saying the effects are similar to the effects
of
spontanious combustion in coal waste tips.
I must admit, I have always thought these fires were caused by
people
scavenging the tips for coal, what evidence is there for spontanious
combustion?
George
