However, the way we handle data most certainly has. ... be done by taking coal samples from the conveyor belt and analyzing them in a laboratory. ... allow calculation of the Calorific Value of the conveyed coal.
closed motor was introduced to the British coal industry, specifically for small width conveyors on large coal conveyor ''boom'' loaders. The ingress of coal dust and slurry into the internal bearings via the sealing arrangement caused premature failure to these units, and hence, all confidence for this concept was lost. The market

BRITISH COAL SEALING TECHNOLOGY STILL RELEVANT TODAY! For many years British Coal Ltd, the major state owned organisation, was the primary producer here in the UK of both deep mined and open cast mined coal – producing millions of tons annually. Accordingly they also had a very high level of input into the technical aspects of conveyor system
A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ead of the face and the back abutment, that is, the settled packs behind the face.
