Abstract
The U.S. Bureau of Mines has been investigating methods and technology that, when applied to existing continuous coal mining machines, may improve production and safety. Toward those goals, a microcomputer network has been designed that provides automated control and monitoring of all mining machine systems using a single twisted-pair cable (two-conductor stranded wire twisted together to provide a level of noise rejection). The network also provides connections for intelligent sensors and systems for navigation and diagnostics. The flexibility of the network is demonstrated in that features can be added and removed without redesigning the whole system. A general description of the network's integration to a Joy 16cm, Joy 14cm, Jeffrey 102, and a custom-built auger machine is provided. The microcomputer networks for the Joy 16cm and the Jeffrey 102 have been installed onboard the mining machines and have been extensively tested at the Bureau of Mines test facility. The Jeffrey 102 system has also been tested in an actual highwall coal seam. Both systems have performed satisfactorily. The microcomputer networks for the Joy 14cm and the auger miner have been tested and await installation on the respective machines.
