Abstract: When we focus on the metal and nonmental mine accidents as well as the occurrence reasons during 2003~2012,we can conclude that poisoning choke is the main reason for that metal and nonmetal mine safety production situation is difficult to improve fundamentally.The imperfect mine ventilation system,the chaotic ventilation safety management,the illegal use of fire under the mine,the nonuse of flame retardant materials and the blind rescuement are all reasons for poisoning suffocation accidents when we pay close attention to plenty of typical mine accident.For these reasons,we accordingly put forward some specific prevention countermeasures and suggestions,such as improving the mechanical ventilation system,equipped with self-rescuers and poisonous and harmful gas detection equipment,elimination of old equipment,using non-fire-retardant materials,strengthening emergency measures and so on.The practical applicability make it have guiding significance for preventing and reducing the poisoning suffocation accidents in metal and non-mental mine.
