摘　　要：分析了井田内重力滑动构造形成机制及对二_1煤层的影响,得出局部厚煤层位于重力滑动构造断坪前缘地段,且局部厚煤层也是瓦斯富集区段的结论,对煤矿开采矿井地质工作和预防瓦斯突出具有指导意义。Forming mechanism of gravity gliding structure in the field and its effect on first section of the second coal seam were analyzed, which concluded that local thick coal seam was located at the front of the gravity gliding structure fault flat and it was also methane-rich zone, which provided guidance for mine geology working and gas outburst prevention.

关 键 词：重力滑动构造 断坪前缘 厚煤带 瓦斯富集带
