2010年11月25日16时55分，××煤矿发生一起特别重大瓦斯爆炸事故，造成26人死亡，43人受伤，直接经济损失2130万元。
一、矿井概况
该煤矿属个体私营企业。2007年7月开始筹建。2008年3月，在未取得采矿许可证、无初步设计、安全专篇未经审查批准的情况下，一号井和二号井同时违法违规开工建设；2009年12月，××省煤炭工业局同意建设该煤矿。该矿未进行瓦斯等级鉴定，未安装瓦斯监测监控系统。2009年1月～2010年10月，该煤矿原煤产量为45927.4t，其中二号井41527.4t。此次事故发生在该煤矿二号井。
2010年1月，该矿因手续不全被国家煤矿安监局和××省人民政府公告为关闭矿井。
二、事故原因
1．事故的直接原因：矿井通风系统不合理，通风设施不合格，矿井漏风严重，放炮后涌出的瓦斯和掘进作业点溢出的瓦斯致使瓦斯积聚，达到爆炸浓度界限；因煤电钻综合保护装置供电电缆绝缘损坏，造成芯线短路，产生火花，引起瓦斯爆炸。
2．事故的主要原因
一是该煤矿无视国家法律、法规，拒不执行停产指令，违规建设，非法生产。该煤矿二号井以包代管，特殊工种无证上岗；矿井无正规设计，采掘布置混乱；矿井漏风严重，串联通风，未安装瓦斯监测监控系统；井下机电设备失爆现象严重。
二是××镇煤炭分局未采取有效措施彻底制止××煤矿违规建设和非法生产。××县煤炭工业局明知××煤矿手续不全却违规向该矿下发开工通知，明知××煤矿属于违规建设、非法生产矿井却研究上报置换保留该矿，且在煤矿整顿关闭工作中弄虚作假。××县煤矿安全监督管理局对××煤矿违反停建指令多次打开密闭违规建设和非法生产的问题监管不力。××市煤炭工业局明知××煤矿属于违规建设、非法生产矿井，却研究同意置换保留该矿，对煤矿整顿关闭工作中存在弄虚作假的问题失察。
三是××县、××镇国土资源管理部门明知××煤矿在没有取得采矿许可证情况下开工建设，却未对××煤矿进行查处和取缔。××县、××镇公安部门在××煤矿未提交有效工商营业执照的情况下，违规审核、批准该矿购买火工品。
四是××镇人民政府未能督促有关部门采取有效措施制止××煤矿违规建设和非法生产的违法行为。××县人民政府对县煤炭工业局在煤矿整顿关闭工作中存在的弄虚作假问题失察。××市人民政府对富源县人民政府上报的关闭矿井方案审核把关不严。
五是××电网集团××县供电有限责任公司在××煤矿未能提供用电工程项目批准文件及完整的相关用电资料情况下违规批准供电。
六是××煤矿安全监察局××监察分局监察三室在未到矿井现场检查的情况下，违反执法程序下达对××煤矿的现场处理决定书。
3．经调查认定这是一起责任事故。
(三)对事故责任人员的处理
移送司法部门处理12人，给予党纪、政纪处分22人。
(四)对事故煤矿的处罚及对有关部门的处理
没收××煤矿违法所得734.8万元，并处违法所得5倍的罚款3674万元。
依法关闭××煤矿。
