摘　　要：大倾角工作面两巷掘进布置及端头支护方式对维护端头区安全作业空间、保证工作面正常推进具有重要意义。对比分析了大倾角工作面两巷多种掘进布置方式和几种常见端头支护方式的优缺点,介绍了影响巷道布置的几个关键要素,提出了大倾角端头支护原则,为合理确定巷道布置、巷道断面尺寸及端头支护方式提供了依据和可行方法。The study on roadway layout and the face end support pattern for large inclined angle working face is important significance for maintaining safe working space and guaranteeing drawing speed of working face. This paper analyzes the advantages and disadvantages of a variety of roadway arrangement modes and common face end support patterns for large inclined angle working face,introduces several key factors that would influence roadway layout,proposed the principle of face end support,which provided theory basis and feasible method for the reasonable roadway layout,cross-sectional dimensions and support pattern for face end.
