Traditional slope stability analysis and design methods, such as limit equilibrium method and continuum numerical methods have limitations in investigating three dimensional large scale rock slope stability problems in open pit mines associated with stress concentrations and deformations arising due ...
open-pit mining [¦ō·pən ¦pit ′mīn·iŋ] (mining engineering) Extracting metal ores and minerals that lie near the surface by removing the overlying material and breaking and loading the ore. Also known as open-cast mining; opencut mining. ...
existing open pit coal mines. After that, the ATC is expanded for the next 30 years by specific mining and milling indices. The study introduces an econometrics model to estimate mining and milling cost index via the Marshal and Swift equipment cost index ...
Lignite in open-pit mines often self-ignites, especially in areas where subsurface mining occurred. Also, the lignite in many waste piles often spontaneously heats and combusts. Based on the temperature that rock in the waste pile is exposed to, a variety of secondary minerals may nucleate, inc...
Slope monitoring in the surface mining industry has become routine practice, supporting mining staff in the management of geotechnical risks. Interferometric radar technology has emerged in the last ten years as a leading edge tool for this purpose. The success of interferometric radar technology is ...
