Abstract
Objective was to develop and evaluate the concept for the Connected Extensible System (CES), a mobile bridge type continuous haulage system which employs extensible rather than fixed-length bridges. Optimum applications for the CES were identified. Concepts were developed for the interfaces between system components and between the CES and the continuous miner and the room conveyor. Configurations were chosen for the CES which optimize system use in the applications identified. Cost estimates were prepared and general operating specifications were defined. Chain was selected as the preferred conveying element. A cost-effectiveness study was conducted by Pennsylvania State University under a subcontract. The CES appeared to be a logical choice over shuttle cars in low to medium seam mines and over conventional continuous haulage in seams up to 80 inches if 88% availability is obtained, and if typical entry and crosscut centerline distances are employed. Longer centerline distances imply clear advantages for the CES concept. (ERA citation 06:034263)
