| 摘 要： | 突出矿井自燃煤层采用U+L型通风方式的采煤工作面,将会使采空区自燃三带重新分布,通过采用数学模型解算、取气分析等综合技术,可以准确地划分出采空区水平和垂直自燃三带的范围,指导工作面安全、科学地开展防灭火工作。 |
| 关 键 词： | U L型通风方式 采空区 自燃 三带划分 |

| Abstract: | On working face in coal seam with outburst danger and spontaneous combustion trend,if U+L type ventilation method was adopted,three zones of gob spontaneous combustion would be redistributed.By the combined method of numerical model calculation and gas analysis,horizontal and vertical boundary of spontaneous combustion three zones of gob can be zoned accurately,this will provide safe and scientific technology basis for fire prevention and extinguishment. |
| Keywords: | U L type ventilation method gob spontaneous combustion distribution of three zones |
