摘　　要：分析阐明构造煤和煤与瓦斯突出问题的关系,为矿区的安全生产提供有效准确的地质信息,从层滑构造的角度探讨构造煤的成因及分布规律,研究煤与瓦斯突出问题和构造煤的关系机理。研究矿区层滑构造与构造煤的关系流程:基于钻孔测井曲线判识构造煤的特征和分布、构造煤类型、发育位置及其厚度,通过层滑构造的分布发育特征来探讨构造煤与层滑构造的关系。结果表明:潘集矿区11-2煤层的构造煤类型主要为Ⅱ类和Ⅲ类,矿区层滑带主要集中在煤层底部,对煤层底板造成较严重破坏。矿区主要发育断裂式层滑构造,造成煤层揉皱破碎较少。构造煤发育程度分布是矿区中西部是深部比浅部强,矿区东部是浅部相比于深部较发育,深部构造煤不发育。The paper analyzed and stated the relationship between the tectonic seam and the coal and gas outburst problem in order to pro-vide the effective and accurate geological information for the safety production in the mining area.From the view point of the seam sliding structure,the paper discussed the formation and distribution law of the tectonic seam and studied the relationship mechanism of the coal and gas outburst problems and the tectonic seam.The relationship procedure between the seam sliding structure and the tectonic seam in the mining area would be based on the drilling logging cures to judge the features and distribution of the tectonic seam,the tectonic seam type,the development location and thickness.The study on the distribution features of the seam sliding structures was applied to discuss the relationship between the tectonic seam and the seam sliding structure.The study results showed that the tectonic seam type of the 11-2 seam in Panji Mining Area would mainly be II type and III type,the seam sliding zone in the mining area would be mainly concentrat-ed at the bottom of the seam floor and thus the seam floor would be seriously destroyed.There was a broken seam sliding structure mainly developed in the mining area and there was less folding broken in the seam.The development degree distribution of the tectonic seam would have more deep section than the shallow section in the Midwest of the mining area and would have more shallow section than the deep section in the east part of the mining area.The deep tectonic seam was not developed.
