Past efforts to estimate methane emissions from underground mines, surface mines, and other coal mine operations have been hampered, to different degrees, by a lack of direct emissions data. Direct measurements have been completely unavailable for several important coal mining operations. A primary goal of this study was to collect new methane emissions measurements and other data for the most ...

Since the first record of a colliery explosion in Belgium, nearly 300 years ago, significant improvements have been achieved in the prevention of explosions in mines. However, based on the past surface TBM project safety statistics, gas explosion hazards are not unique to coal mines but also occur in TBM projects with 48 explosion fatalities recorded worldwide calling for continued diligence an...

The Itai-Itai disease case is one of four major pollution-related lawsuits occurring in Japan after World War H. This paper, which is based on investigations of the pollution source, the Kamioka mine, considers (1) the history of the disturbances to the environment caused by the Kamioka mine; (2) the Itai-Itai disease suit; (3) the pollution nprevention measures and methods of the Kamioka mine ...

water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. the purpose of this study is to make an assessment of groundwater quality in an underground mine site in portugal with a view of determining the pollution potential of groundwater. in the corresponding surface area of this underground mine, intersections of fou...

Biological networks are usually used to model interactions among biological macromolecules in a cells. For instance protein-protein interaction networks (PIN) are used to model and analyse the set of interactions among proteins. The comparison of networks may result in the identification of conserved patterns of interactions corresponding to biological relevant entities such as protein complexe...

This document presents material supplementary to our companion paper A Decomposition-Based Heuristic for Collaborative Scheduling in a Network of Open-Pit Mines. In this companion paper, we consider the short-term production scheduling problem for a network of multiple open-pit mines and ports. Ore produced at each mine is transported by rail to a set of ports and blended into signature product...

In this paper we consider the problem of optimising the construction and haulage costs of underground mining networks. We focus on a model of underground mine networks consisting of ramps in which each ramp has a bounded maximum gradient. The cost depends on the lengths of the ramps, the tonnages hauled through them and their gradients. We model such an underground mine network as an edgeweight...

The St. Barbara mine is a visitor having large amount of timbering support which deteriorating fast due to the high humidity conditions. air conditioning system mining not suitable and also expensive for implementation in shallow non-productive mine. As there are no usual contaminants mines, ventilation could be powered only when dew point outside below strata temperature. Applying this rule wo...
