Methodological principles of effective and safe open-pit mining at deep horizons of mineral deposits

As a result of integrated investigations new methodical fundamentals of effective and safe technology for open pit mining of deep levels of deposits have been developed. The method is arranged by stage-by-stage designing of seismic, geological engineering and geotechnical models in the scale of ranks from upper crust to single unit of mine. For achievement of this technology it is necessary to build up the complex monitoring system for inspection stability of construction units of open pit mining. The monitoring systems have to be appropriate to scales of investigations and objects.
