Highwall Mine Design, Rock Testing, and Longwall Prefeasibility Study
AAI has performed a variety of services for Colowyo, including highwall mine design, underground prefeasibility, and rock mechanics core testing in conjunction with a major drilling program. Using AAI-developed guidelines, Colowyo has successfully performed highwall mining in several areas of the mine, including the mining of multiple seams in the highwall. Highwall mining design efforts are summarized in the following technical paper: Highwall Mining in a Multiple-Seam, Western United States Setting–Design and Performance
