The risk assessment approach for the establishments concerned by the Seveso II Directive requirements can be grounded on the determination and the aggregation of 3 indexes: the gravity index, the propagation flow index and the vulnerability index. Based on the national and EU legal requirements concerning the prevention and control of major accident hazards involving dangerous substances, the paper has as main goal to present an expeditious methodology for gravity index determination as a function of the dangerous...

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...
