  • The Hazards of 19th Century Coal Mining

    There were two big engineering problems in mining coal underground: A system to drain water from the mine. A system to ventilate the mine and to provide fresh air to the miners. A special problem in coal mines was the methane (a gas) that sometimes accompanied coal, and which could--and too often did--catch fire and explode. Andrew Roy was one

  • Underground coal mining

    Most underground coal mines suffer from methane gas releases from coal or surrounding rock strata, both during and after the mining process. Methane gas release represents a severe mining hazard and extensive ventilation is crucial to provide a safe work environment. For this reason, up to 200 meter long degasification holes are usually drilled.
