Waste dumps are widely used to discharge stripped mine wastes in open pit mining methods. As progresses, the height of waste will increase gradually, which may induce sliding failure once exceeds a critical value. Therefore, estimation maximum dumping is crucial life-cycle use dump. However, published information about extremely rare. In this study, estimated based on strength-reduction techniq...

Jefferson Laboratory's kW-level infrared free-electron laser utilizes a superconducting accelerator that recovers about 75% of the electron-beam power. In achieving first lasing, the accelerator operated "straight ahead" to deliver 38-MeV, 1.1-mA cw current for lasing near 5 &mgr;m. The waste beam was sent directly to a dump while producing stable operation at up to 311 W. Utilizing the recircu...

Driverless haulage trucks have recently been developed for open pit mines. To predict the benefits of an Autonomous Haulage System (AHS), a deterministic/stochastic model has been created to compare AHS to a manual system by estimating benchmarked Key Performance Indicators (KPIs) such as productivity, safety, breakdown frequencies, maintenance and labor costs, fuel consumption, tire wear, and ...
