Run-of-mine coal/stone monitoring
The evaluation of sensors was carried out on a test facility comprising a re-circulating conveyor system. In all, three sets of trials, involving the assessment of five beltweighers, two profile measurement systems, a natural gamma detector and a test version of a dual-energy gamma transmission system (BCS1) were completed. This project has resulted in the availability of an on-line monitor capable of providing colliery management with a rapid measure of the run-of-mine (rom) ash content. Versions have been developed for use on both underground and surface feeders and surface belt conveyors. A version designed for underground conveyors is nearing completion. Accuracies (1 sigma) of +/- 5 % for rom belts and +/- 3 % for rom feeders have been achieved.
