| 摘 要： | 义煤集团杨村煤矿在D13131综放工作面回采过程中遇隐伏断层,造成工作面支护困难,煤壁片帮严重,工作面支架多数压死不能推进,被迫提前终采拆除.工作面终采前,受断层影响全月推进了8 m多,采空区浮煤出现自然发火迹象,工作面上隅角CO浓度一度在100 x 10-6以上,工作面及上隅角往外20 m范围内普遍存在高冒区,严重威胁工作面的安全拆除.通过多次的现场观察分析,制订了针对性强的综合防灭火专项技术方案和措施.该方案的实施,取得了良好的效果,确保了工作面的安全拆除.

| Abstract: | While mining on D13131 fully-mechanized top coal caving face in Yangcun Mine in Yima Coal Group Co.,Ltd.,it encountered with a blind fault,this brought many difficulties to supporting.Rib falling of coal wall is serious.Most hydraulic supports were pushed down to stop forward,so they are forced to be demolished early.Before mining-pause period,working face advanced distance was 8 meters per month controlled by faults.In old coal mining area,evidence of spontaneous combustion occured.The density of CO in the... |
