Selby spine conveyor belt management and control system
A key element of the mining plan of the Selby coalfield is the coal clearance strategy, designed to gather coal from the satellite mines to central distribution points and to transport it to the surface at a rate of up to 3000 tonnes per hour through drifts (called spines) on one of two central conveyor belts. Because of the length of these belts, the variable gradients in the drifts, adjustable belt speeds and independently variable coal discharge rates from the bunkers along the spines, maximising coal throughput without exceeding the traction limits of the conveyor drives and without spillage at the transfer points is a complex problem. A technique for modelling the flow of coal along the spine conveyor belts has been developed. This technique is used by the Spine Belt Management System to predict any conveyor overloads. Once predicted, any overload will be avoided by optimising (reducing) the discharge rates from the bunkers. This report describes the remote monitoring and control system developed using available technology for the spine conveyors and the software that was developed to provide overload protection.
