Equipment Introduction underground COAL
Equipment. In early days, development was carried out by hand working (i.e. digging with pick and shovel, usually assisted by the use of explosives to dislodge most of the coal. Roof support was by hand set timber props and bars. Rail tracks were extended to the face and coal was hand loaded into skips, mostly horse drawn at that time.
