The loosened coal drops to the floor where rotating steel arms thrust it into the "throat" of the machine, a conveyor belt which carries the coal to the rear for loading into shuttle cars or a mine conveyor system.
Cutting machines that remove coal with rotating drums studded with picks are the principal sources of dust in mechanized mining operations. These include so-called continuous miners and longwall mining machines. Longwall mining machines usually produce larger amounts of dust than do other methods of mining. Dust dispersion can
These pages show mining machines, and offer some information about the introduction of machinery into mining. The point of the pages is to appreciate the dynamic quality of the industrial revolution.
