R20s COAL FACE - TAILGATE END SHOWING HYDRAULIC ROOF SUPPORTS
high pit wilma :- THIS...Was THE sheer hell place to work in...70 to 100 yard roof falls of stone strata , was common place. When the goaf used to make it's break , the whole roadway, used to shake like an earthquake, the air used to change direction, and the thunderous noise of the strata above breaking up was a terrifying experience to the young -and the experienced men.
