Methane emissions released into the atmosphere during coal mining, exerts a double environmental impact, namely they participate to the ozone layer depletion process and, simultaneously, they have a significant contribution to the enforcement of the greenhouse effect. On the other hand, this methane can be used by the mining operators, as main or ancillary fuel resource for energetic purposes. Until now, in Romania an overall energetic potential study was not systematically carried out, regarding the hard coal bas...

Heat and exhaust emissions are representing two of the major health and safety issues induced by the presence of Diesel-mounted equipments in underground mines. The first one has greater effects in deep mines, while the second one requires a careful dimensioning of ventilation airflows in all mines. Taking into consideration the higher exposure level of Diesel mounted equipment drivers at the noxious products contained in the exhaust emissions, it clearly appears as a major safety concern the need for an expeditio...
