摘　　要：为了解决松河矿井1031工作面回采期间瓦斯超限问题,在1031工作面顶板布置走向高位巷进行采空区卸压瓦斯抽采,并分析了高位巷层位与抽采效果的关系。应用效果表明:采用顶板高位巷进行卸压瓦斯抽采,降低了上隅角及回风流瓦斯浓度,解决了工作面回采期间的瓦斯超限问题,为矿井工作面的安全生产提供了技术保障,同时为顶板高位巷抽采技术在其他高瓦斯矿的推广应用提供了切实可靠的经验。In order to solve over-limit methane problem in 1031 mining face of Songhe Mine,high-position roadway was driven in roof to drain methane in gob.The relationship between layer location of roadway and methane drainage effect was analyzed.Application effect showed that applying roof high-position roadway to draining methane could reduce methane concentration at top-corner and air-return roadway and solve methane over-limit problem in mining face.This technology provided technical guarantee for safety production and reliable experience for other mines with high methane content.
