摘　　要：根据深埋厚煤层某矿12209工作面的地质条件,利用理论计算和FLAC^(3D)软件综合分析了不同宽度小煤柱对沿空掘巷围岩稳定性的影响,得出小煤柱宽度8 m为最优方案,对类似地质条件下沿空掘巷小煤柱的留设提供了思路和参考。Based on the geological conditions of 12209 working face in a certain coal mine in deeply- buried thick coal seam, uses the theoretical calculation and FLAC3D software to comprehensively analyze the influence on the stability of the roadway rock of driving along goaf from the fenders with different width, reaches that 8 m in fender width is the optimal decision, and provides the thinking and reference for the establishment of fender of roadway driving along goaf under the similar geological conditions.
