Federal regulations require refuge alternatives (RAs) in United States underground coal mines. If the thermal environment in an RA becomes severe, trapped miners could experience heat exhaustion or heat stroke, which is deadly. Regulations for underground coal mine RAs mandate an apparent temperatur...

Unconventional gas wells are being drilled through coal reserves in Pennsylvania, West Virginia, and Ohio. The ability for both mining and gas producing activities to coexist safely is a continuing question for federal and state regulatory entities and for industry representatives. A hypothetical, g...

Federal regulations require refuge alternatives (RAs) in United States underground coal mines. The thermal environment of RAs is a concern because, if the thermal environment in an RA becomes severe, trapped miners could experience heat exhaustion or heat stroke, which is deadly. To prevent exposing...

During an underground mine fire, the presence of smoke and toxic gasses, low visibility, and changes in the ventilation system will make it extremely difficult to identify evacuation measures and optimum path to safety. This paper presents an algorithm for solving minimum cost flow network problem (...
