摘　　要：分析了红岭煤矿14161综放工作面上隅角瓦斯积聚的原因,采取高位钻孔抽采、上隅角埋(插)管抽采、增加工作面风量、上巷插管抽采和水射流风机处理局部瓦斯积聚等瓦斯综合治理措施,彻底解决了上隅角瓦斯超限问题。采取上述综合措施后,该工作面上隅角瓦斯浓度降低到0.4%以下,局部最高瓦斯浓度也降低到0.5%以下,工作面单产由原来的2200t提高到3100t,保证了工作面的高产高效。The reasons for the gas accumulation in the upper corner at No.14161 fully mechanized mining face of Hongling Coal Mine were analyzed.The comprehensive gas control measures completely solved the gas overrun in the upper corner,including drainage from high-level boreholes,drainage with buried pipe in the upper corner,the increase of air volume at mining face,pipeline drainage in the air-return roadway and the control on local gas accumulation by water jet blowers.The application showed that the gas concentration decreased to below 0.4%in the upper corner,and the highest local gas concentration dropped to below 0.5%.The coal output at single mining face increased to 3100 tfrom 2200t,ensuring the high productivity and high efficiency.
