Active learning has shown to reduce the number of experiments needed to obtain high-confidence drug-target predictions. However, in order to actually save experiments using active learning, it is crucial to have a method to evaluate the quality of the current prediction and decide when to stop the experimentation process. Only by applying reliable stoping criteria to active learning, time and c...

An extensive finite element analysis of stability of mining openings at the uranium mine GEAM D. Rož́ınka was firstly performed in the years 1996-2002, see Fig. 1. The final conclusions of this analysis advocate the use of a new mining technology (underhand stoping) and safety of mining in greater depths 950-1100 meters under the surface. At present, due to the price increase of the uranium, the...

Stope design optimisation defines three-dimensional extraction volumes aiming to maximise cashflows, subject geotechnical and operational constraints. Available stope layout methods are deterministic, failing account for grade uncertainty variability that affect locations sizes, as well value. A two-stage stochastic integer programming model is proposed, integrating quantified through geostatis...

The technogenic impact of mining on the environment is analyzed and transition to geotechnology with stowing reduce operations proposed. results research work devoted justification parameters development salt deposits definition influence dynamics deformation underworked rock massif are presented. relevance aimed at creating a safe efficient technology for from systems natural maintenance stopi...

The aim of the research is to assess possibility using energy-dispersive X-ray fluorescence method directly at stoping operation site. To meet this objective, a hand-held spectrometer expert class NITON XL2 brand was selected. This will solve problem developing an express for assessing explosive and fire-hazardous properties sulfur-containing or pyrite-containing ore. development dictated by ne...

Cemented rock fill (CRF) is commonly used in cut-and-fill stoping operations underground mining. This allows for the maximum recovery of ore. Backfilling can improve stope stability workings and then ground whole mine site. However, backfilling step scenarios vary from site to paper presents investigation five different their impacts on stopes at four mining levels. A comprehensive comparison d...
