A feasible solution is to create a single network model to simulate both the large scale ventilation model and the smaller scale rollback behavior. This can potentially be achieved by creating a detailed high density three-dimensional mesh of pathways bounded by the airway around a fire which then feeds into the simpler network of a large scale ventilation model. The high density mesh allows a ...

CLIO (Cryogenic Laser Interferometer Observatory) is a Japanese gravitational wave detector project. One of the main purposes of CLIO is to demonstrate thermal-noise suppression by cooling mirrors for a future Japanese project, LCGT (Large-scale Cryogenic Gravitational Telescope). The CLIO site is in Kamioka mine, as is LCGT. The progress of CLIO between 2005 and 2007 (roomand cryogenic-tempera...

A reliability analysis of a dumper machine is performed using the neural network model. A metaheuristic algorithm is applied for proper parameter selection for the neural network. A time series approach is applied in the reliability analysis to forecast the dumper’s future failure time. The time series analysis is performed using the neural network model, where the numbers of input variables fo...

Assessment of soil quality is one of the key parameters for evaluation of environmental contamination in the mining ecosystem. To investigate the effect of coal mining on soil quality, opencast and underground mining sites were selected in the Raniganj coalfield area, India. The physical, chemical, and biological parameters of the soils, and trace metals and PAHs (polycyclic aromatic hydrocarbo...

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...

The Canadian Space Agency (CSA), through its Analogue Missions program, supported a microrover-based analogue mission designed to simulate a Mars rover mission geared toward identifying and characterizing methane emissions on Mars. The analogue mission included two, progressively more complex, deployments in open-pit asbestos mines where methane can be generated from the weathering of olivine i...

CDFP-Mine, a novel approach for finding huge Colossal Pattern Sequences (CPS) from High Dimensional Biological Datasets is talked about in this paper. CDFP-Mine has successfully found Determinate Frequent Patterns (DFP) which is additionally advanced into a DFPT + tree to produce CPS with vector intersection operator. CDFP-Mine influences utilization of a novel incorporated data structure calle...
