How mines were ventilated
How the mines were ventilated and drainer. One of the reasons for the mine strike of 1912 was the poor maintenance of ventilation and draining of the mines. If the ventilation machinery stopped working foul gases would gather in passages and corridors, and if the pumping apparatus were to cease operations the water, would rapidly rise and flood all the main workings of the mine. In the typical case shown here the water automatically drains down to some old workings beneath the upcast shaft. Behind the two shafts is shown a view of the mine with the workers at the coal face
