In the case of Roşia Poieni open pit mine level +805 m was established as a daily operating limit; division into benches based on this by dividing horizontal slices with thickness 15 m, equal to height bench. Thus, there were 27 in Curmătura area and 23 Ruginiş area. The general slope angle set at 35°, for which tailings volumes implicitly opening-up coefficient calculated. stability analysis p...

Here we report on a metagenomics investigation of the microbial diversity in a serpentine-hosted aquatic habitat created by chrysotile asbestos mining activity at the Vermont Asbestos Group (VAG) Mine in northern Vermont, USA. The now-abandoned VAG Mine on Belvidere Mountain in the towns of Eden and Lowell includes three open-pit quarries, a flooded pit, mill buildings, roads, and > 26 million ...

To effectively manage the stability of in-pit dumps with an underlying weak layer, a new plan for treatment staged floor during life mine was proposed in this study. Based on direct shear test results, properties contact surfaces between dumped spoil, and mudstone were determined. Taking Baiyinhua No.1 Open-pit Mine as example, surface spoil determined its cohesion to be 25.78 kPa, internal fri...

This study aims to fully explore the influence of rock joint roughness in slope stability analysis an open mine. Therefore, based on least squares parameter estimation method, a generalized shear strength coupling roughness, which is used evaluate design, was established by matching formula reflecting relationship between coefficient and parameter. Firstly, verify calibrate model, physical dire...

This research project developed an adaptive stochastic optimisation approach for multi-period production scheduling in open-pit mines under geological uncertainty, and compared it to existing two-stage method. new rolling-horizon updates the model each time period as information becomes available. Numerical tests carried out earlier on open-pits of different sizes showed that, average, policy g...
