摘　　要：煤层倾角影响巷道断面形状选择。采用数值分析方法,分析倾斜煤层不同断面类型巷道的破坏形式,发现拱形巷道围岩稳定性明显好于直边巷道;近水平煤层适合选择矩形断面,缓倾斜及倾斜煤层适合选择倒梯形断面,大倾角煤层适合选择异形断面,当围岩地质条件较差时选用拱形或斜拱形断面,急倾斜煤层适合选择梯形断面。The dip affects roadway cross-sectional shape choosing.Based on statistics,we use numerical analysis method to study failure modes corresponding to the section of roadway under different inclination conditions.Studies have shown that:surrounding rock stability of arched tunnel is significantly better than a straight edge roadway.Gently inclined and inclined seam for selection inverted trapezoidal cross section,for selecting high inclined seam profiled section,when the selection of poor geological conditions surrounding rock arch arched or oblique section,Steep Seam suitable choice trapezoidal cross section.
