摘　　要：分析了巷道支护的设计原则,并提出了应结合实际地质条件来合理设计巷道支护的策略,通过进一步了解不同锚固方式以及顶板角下围岩应力场分布情况,从实际出发选用最佳的巷道围岩变形控制技术,能有效控制巷道围岩变形,更好地保障了矿井安全生产。The design principle of roadway support is analyzed,and the strategy of roadway support should be reasonably designed with the actual geological conditions.By further understanding different anchoring methods and the distribution of the stress field of the surrounding rock under the roof angle,the best roadway surrounding rock deformation control technology is selected from the practical point of view,which can effectively control the deformation of the surrounding rock of the roadway and better ensure the safe production of the mine.
