Cheyenne Mountain Air Force Station – Hoisting System Feasibility Study & Designs
Client: HB & A for, US Air Force
Location: Colorado, United States

MES was contracted in 2005 as an add-on to its support for rock removal for a new elevator system study. This was to perform the feasibility for underground tunnel rock removal and tunnel re-support for improved underground material hoisting systems for the facility. The improved hoisting systems were for the blast valves and for hoisting replacement utility systems to the command center building roof.

Critical issues included addressing rockfall and rock stability, environmental, health and safety, operational, access, security, power, ventilation, haulage, and construction feasibility concerns. Preliminary drawings and a cost estimate were provided for the utility hoisting system rock removal. Detailed bid-ready construction drawings, specifications, and work plans were prepared for the blast valve hoisting system rock removal.

MES mining engineer Matt Collins performed underground surveying and 3-dimensional modeling of the rock cuts. Deere and Ault engineer Dr. Christoph Goss, P.E. provided a peer review of MES’s specifications for rock removal, shotcreting, and rock bolting.
