分析了立胜煤矿“1·5”特别重大电气火灾事故的发生时间、事故类型、发生地点及事故原因,认为该次事故为火灾事故,发生在2010-01一05T12:05中间井三道暗立井内,并得出导致该次事故的直接原因:中间井三道暗立井内有一根老化、破损的非阻燃电缆短路着火；矿井主要通风机在事故发生前没有运行,没有独立通风系统,通风设施不全,违规串联通风,中间井缺乏供水系统；矿井在-240m水平以下区域无逃生通道；井下作业人员没有佩带自救器.最后提出了预防该类事故发生的措施:(1)严禁使用非阻燃电缆和老化、破损电缆；(2)严禁使用明令禁止的电器开关和设备,矿井供电系统必须按规定和标准设置漏电、过流和接地保护装置,并整定和校验；(3)除掘进工作面和临时作业场所外,井下其它巷道和作业地点均应有不少于2条通达地面的步行安全通道,每一个水平到上一个水平和各个采区都必须至少有2个可与通达地面的安全出口相连的行人安全出口；(4)矿井提升设备必须具有煤安标志；(5)矿井主要通风机不得停止运行,矿井必须具有独立的通风系统,必须按《煤矿安全规程》要求设置通风设施；(6)井下必须安装供水系统；(7)井下作业人员必须佩带压缩氧自救器.%The paper analyzed time, type, place and causes of "1·5" vital electrical fire accident in particular of Lisheng Coal Mine, and considered that the fire accident happened in the No. 3 blind shaft of the central shaft at 2010-01-05T12:05. It got causes of the accident: an old non-fire resistant cable fired because of short current; main ventilator had not run before the accident; there were incomplete ventilating equipments as well as wrongful series ventilation, no independent ventilation system, no water supply system in the central shaft and no escaping passages under -240 m mining level; undergroundminers had not carried self-rescuers. Finally, it proposed following preventive measures of the kind of fire accident: (1) Do not use non-fire resistant cable and old cable. (2) Do not use electrical switches and equipments prohibited by explicit order, and protection devices for leakage, over-current and grounding must be set, tuned and calibrated in mine power supply system according to corresponding rules and standards. (3) There must be no less than 2 safe walking passages leading to the ground in tunnels and working areas besides driving working faces and temporary areas, and no less than 2 walking exits connecting to the ones leading to the ground between a mining level and an upper mining level or each district. (4) There must be mine safety sign on mine hoisting equipments. (5) Main ventilator of mine cannot stop, there must be independent ventilating system in mine, and ventilating equipments must be set according to Coal Mine Safety Regulations. (6) There must be water supply system underground. (7) Workers underground must carry oxygen self-rescuer.
