The extension will provide new underground and surface infrastructure, which includes new mine access and conveyor drifts to surface, new coal-clearance systems, overland conveyor systems, wash plant upgrades, new surface facilities, and backbone infrastructure.

“We take pride in the fact that we are applying sustainability principles to our work on this expansive project,” said John M. Dionisio, president and CEO, AECOM. AECOM was previously responsible for providing the feasibility study and detailed engineering services for the project. The first coal shipment from the new mine extension is scheduled for 2012.
