The head of the national coal miners’ union on Thursday urged the Trump administration to impose regulation on silica dust in mines, which researchers believe is responsible for a resurgence of black lung disease in central Appalachia. The demand from … ...
which passes near the mines for which Old Mine Road is named. Although many people refer to the portion of the road from the Gap to this point as Old Mine Road, it really begins here at the copper mines. Although there is no substantial proof, legend says the Dutch started these mines...

These requirements make active treatment quite expensive and impractical: the treatment of AMD that may emanate from abandoned coalmines for hundreds of years. Therefore, ‘passive treatment’ technologies are preferred due to the low cost of maintenance and materials. A common strategy for passively ...
Therefore, four spatial elements contributed to the reclamation project at Bark Camp: dredged material, abandoned mines, fly ash sources, and railroads. Using spatial distribution of these data in the contiguous United States, it was possible to utilize GIS analysis to prioritize areas where ...

Mine Fires in Undergorund Coal Mines The confined enclosure conditions in a mine or a tunnel creates a feedback heat that varies from open fires, being able to have a heat release rate (HRR) four times higher [22]. Besides, fuel-rich fires can also be found, generating large amounts of...
Based on the safety regulations of coal mines, the model classifies the safety levels into four categories. We then apply the model to classify coal mine safety data that we collected. By comparing the classification accuracy of the IAHA-SVM model with that of the AHA-SVM model, we aim to...
