The two primary measures of land mine detection performance are the probability of detection Pd and the probability of false alarm Pfa.These two measures are highly interdependent and must be evaluated together. The relationship between the two probabilities directly a ects the overall performance of the sensor in the eld. In this paper we introduce a novel false alarm non-parametric lter based...

background : in china, over 80% of all work-related deaths in the mining industry occur in coal mines and human factors constitute 85% of the direct causes of coal mine accidents, which indicates that significant shortcomings cur-rently exist in the safety behavior management of chinese coal mine workers. we aimed to verify the impact of human psychological behavior in coal mine accidents syste...

The Schneeberg mine in the south-western part of Saxony (Germany) is flooded up to the overflow level. The mine water discharges via a historical adit to the Zwickauer Mulde river. Although the Schneeberg mine has been flooded for a 50 years period, and it is relatively small, the mine discharges a significant arsenic load at a nearly constant level, which seems to be typical for base metal/ ur...

We proposed a novel ray-tracing based radio waves propagation (RTRWP) Law suitable for under-tunnel complex coal mine workface. The energy consumption model evaluation in complex coal mine workface is derived. Theoretical analysis about calculating the multiple reflections of the radio waves in coal mine workface is also provided. Computer simulations and field tests in workface tunnels show th...

Three local seismic systems were installed by August 2015 in deep underground mines in Sweden – Zinkgruvan Mine (Lundin Mining AB), Garpenberg Mine (Boliden AB), and Kiirunavaara Mine (LKAB) as part of a project for developing new methods for Evaluating the Rock Support Performance (ERSP, Vinnova). The areas were chosen within the most probable volumes where large rockbursts can be expected. Th...

Alga as Achnanthes minutissima among diatoms is a widely adaptable taxon on the state of an aquatic environment. In this study, it was found that diatom had a specific tolerance to heavy metals (Cu, Zn, Pb, and Cd etc.) in river water samples, because the diatom assemblage consisted of almost only Achnanthes minutissima in Kakehashi river and Godani river, which were polluted with waste water f...
