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 .%通过对2003～2012年十年间金属非金属地下矿山事故的分析，从较大、重大事故起数、死亡人数等方面得出中毒窒息事故是制约金属非金属矿山安全生产形势根本好转的主要矛盾，通过对大量典型事故的分析，得出导致中毒窒息事故的主要原因有矿井通风系统不完善、通风安全管理混乱、井下违规动火、未使用非阻燃材料和盲目施救等，针对这些原因，相应地提出完善机械通风系统，配备自救器和有毒有害气体检测装备，淘汰老旧设备和使用非阻燃材料，并强化应急措施等防范对策和建议，具有很好的实用性，对防范和减少金属非金属矿山中毒窒息事故具有指导意义。
