摘　　要：随着煤矿开采深度和强度的增加,巷道交岔点施工面临越来越不利的工程技术条件。文中对深井复杂地质条件下影响交岔点稳定性的主要因素———构造应力、软弱岩性和巷道空间结构以及围岩变形力学机制进行了分析探讨。面对复杂的生产地质条件,采用有针对性的施工方法和科学的支护体系,提高了交岔点的施工速度,并取得了良好的支护效果。With the increase of the depth and intensity of coal mining, the construction of roadway junction point has been facing more and more unfavorable engineering technic conditions. This paper analyzes and discusses the main factors of influencing the stability of junction points under complicated geological condition of deep wells, namely tectonic stress, soft rock, roadway space structure and the mechanism of wall rock deformation mechanics. For complicated geological condition of production, a targeted construction way and scientific supporting system are used, which improves the construction speed of junction point and attains good supporting results.
