Tech talk: Early coal mining machines and their use

It appears that the bord-and-pillar technique described in 1749 is still in use, but it being rapidly phased out in favor of longwall mining. Details of the machinery used is not given, but there is a limit to the possible ways of extracting coal. N.S.W. coal is largely in quite thick seams (8-12 feet) and dips are very slight in most mines.

8.6: Coal

4.3.1: Coal Mining and Processing, and Electricity Generation. There are two primary methods of coal mining: strip mining and underground mining.Strip-, or surface-, mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams. It is typically used when the coal is less than 200 feet underground.
