▪ Core elements must be switched to NS-3 routines ⁃ event scheduling ⁃ absolute and relative time operations ⁃ logging ▪ Events in NFD should be hooked up with tracing facilities of NS-3 ⁃ tracing of traffic flow, CS, PIT, FIB ▪ NFD stack configuration needs to be streamlined with ndnSIM helper ⁃ configure node parameters, set up and update FIB, forwarding strategy, etc. ▪ New tracing points ne...

Mixed integer programming (MIP) models are used for long-term production scheduling of open pit mines. However, formulations based on binary variables for mining blocks require too many variables and are often difficult or impossible to solve. This paper presents and tests alternative MIP scheduling models that have reduced the number of binary variables and solution times, thus increasing effi...

Geology and the detailed understanding of its properties are fundamental to the optimal design and successful operation of any mine. To that end, extensive fieldwork was conducted at Sandsloot open pit (PPRust— Anglo Platinum) to collect geotechnical information both from exploration boreholes and in-pit mining faces. Over a fie-year period, geotechnical data were collected from 29, 213 m of ex...

To achieve a successful and effective operation, the transition from open pit to underground mining requires accurate planning analysis. Numerical modeling utilizing programs like FLAC3D has been an important tool for simulating analyzing complicated geomechanical behavior connected with this shift in recent years. The use of develop model switch coal soft rocks using room pillar method is expl...

Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...

The Certej basin is situated in the North of Deva town, in Apuseni Mountains and was an important nonferrous mining region. In present the mining activities were stopped, but the acid mine drainage is still affecting the underground water quality. Acid Mine Drainage takes place where sulphide-bearing material is exposed to oxygen and water. This drainage water is characterized by low pH, high s...
