摘　　要：以郭屯煤矿2302回风巷掘进与1307探巷(老巷)贯通为研究对象,利用超前钻孔技术对老巷内积聚的瓦斯及有害气体进行排放,解决了掘进工作面遇老巷,无通道提前对老巷进行瓦斯排放的问题。不仅提高了掘进工作揭穿老巷的速度,确保了巷道的通风安全,还创造了良好的经济效益,为掘进巷道揭穿老巷时提供一定的借鉴。Guotun coal mine 2302 tunneling of return airway and 1307 transfixion of exploration roadway（the used roadway） as the research object,through the use of advanced gas emission technology, emission of goal roadway in the accumulation of gas and harmful gas, solves the tunneling heading face in the used roadway, non-communication ahead of the used roadway gas drainage problems.Not only improve the speed of tunneling to debunk the used roadway ,ensure the safety of the tunnel ventilation, but also create a good economic benefit, provide a reference for the roadway to debunk used roadwav.

关 键 词：探巷贯通 超前钻孔 瓦斯排放 通风安全
