Faced problems and countermeasures of coal mine safety

China is a coal mine-producing country,and coal resources represent a significant share of primary energy in our country.Because of the complexity and variability of the work environment,coal production has always been a high risk industry.With the improvement of technology of coal mine,the accidents have been a certain degree of containment,during the coal mining and production,accidents occur often,and caused major casualties and economic losses.But impediment to coal mine's safe,efficient production seriously,and also with a negative impact on the social,which makes mine safety issue particularly prominent.Aiming at several large mine disaster that occurred in recent years,the current mine production safety problems were pointed out from five aspects: natural conditions,production conditions,investment in science and technology,management level,security training.Some appropriate countermeasures and measures were proposed.It can provide technical reference and basis for the production management of coal mine.
