摘要
通过对白皎矿煤与瓦斯突出资料的综合分析，找出了瓦斯突出与煤层围岩特征、煤层间距变化及断层、褶曲、层滑构造、地表地形特征（悬崖峭壁、山谷沟底）、地应力等的关系，据此编制、完善了矿井瓦斯地质图。瓦斯地质图运用于矿井生产中，有效地遏制了突出加剧的势头，取得了良好的经济效益和安全效益。
A comprehensive analysis on coal and gas outburst occurrences in Baijiao coal mine has indicated the relations between the coal-seam surrounding rock feature of outburst and the space of coal-seam, faults, folds, layers′ structure, earth surface, landform ( sheer precipice and overhanging rock, mountain valley and gullies ) ground stress and some other factors On the basis of the analysis, the gas-geologic map in coal mine has been perfected The application of the map to coal mine production has proved that this map is both infficient and practical
