Sep 03, 2020 Jeremy Crooks Head of Innovation, The Coal Authority. The core concept is simple a borehole is sunk into the workings of the mine, water is pumped to the surface and fed into a heat pump or heat exchanger where its used to heat water thats then circulated around a district heating system. It is, he said, a massively efficient process.

Cdc Mining Feature Coal Mine Explosion Prevention

Dec 09, 2011 Underground coal mining produces finely divided coal dust that deposits throughout the mine and serves as a source of combustible material for coal dust explosions. Limestone powder, known as rock dust, is spread throughout the mine workings on a regular basis. This rock dust serves to inert the coal dust when applied in the proper proportion.
