摘　　要：基于缓倾斜突出煤层的传统石门揭煤技术中存在的穿越石门、煤门距离长、突出危险性大等问题,深入探讨了构造石门顶(底)板法石门揭煤技术。结合薛湖煤矿二2突出煤层2108风巷揭煤具体情况,应用构造顶板石门揭煤工艺,详细讨论了施工过程中应注意的关键环节。实践证明,构造顶(底)板法能够有效安全地揭穿高瓦斯缓倾斜突出煤层。Based on the problems of traditional cross-cut uncovering coal technology in inclined outburst coal seam with high gas,such as long distance through cross-cut and coal gate,large outburst risk,and so on,the technology of structural roof（floor） cross-cut uncovering coal is studied.According to the 2180 airway uncovering coal circumstance of Two-2 outburst coal seam in Xuehu Coal Mine,applying this technology,the key which should be noted in construction process is discussed in detail.Practice has proved that this technology can effectively and safely uncover inclined outburst coal seam with high gas.
