mechanical mining
  |
The Earth Mechanics Institute (EMI) at the Colorado School of Mines (CSM) has been performing basic and applied research and engineering for all types of excavation systems for more than 30 years. The body of knowledge acquired over this time period has allowed EMI to develop methods, which have been verified by field data, to optimally design mechanical mining machines, support equipment, and operations.
