Restructuring of mining activity in Romania resulted in active implementation of reconstruction programs, upgrading and modernization of the mines in the Jiu Valley. These programs were aimed mainly at increasing labor productivity safely. Considering, along with requirements for ensuring a safe and healthy working environment, also the issues related to the drained methane valorization and to environmental protection restrictions it was imposed to rethink the so-called "global methane treatment" at the level of m...

The major changes occurred in Romanian mining industry imposed by the transition to the market economy, concentration of extraction to fewer output units in deeper seams, the high gas emission rates and coal rank, other current specific trends requires new methods to produce the optimum design and operation of a safe and economic methane drainage system. Under the circumstances, the paper describes a mathematical model together with a computer-aided optimization strategy to assist the analysis of the differences b...

The inadequate comprehension of specific haza rds, mainly related to their nature and magnitude, have lead in the past to the occurrence of several catastrophic events in the Romanian mining industry. The mining industry, like other major global industries, must consider and manage risks to business objectives, to remain successful. Management of risks requires a proactive, systematic approach, applied when key decisions are being made across the life cycle of the industry, from exploration to mine closure. Presen...
