Automated extraction system design review

PDF Version Also Available for Download.

Description

The Automated Extraction System (AES) is an advanced fullface continuous mining system designed and built by National Mine Service Co. Since initial testing in a coal mine revealed operational problems, a design review was conducted. Two potential conceptual problems were identified: the roof control concept and the hydraulic sumping concept. It is felt that the combination of uneven and cyclic roof loading may promote roof failure even in bolted roof areas. Critical design problem areas include weight and balance, friction-induced excessive sumping forces, and design complexity.
