中文摘要：
采动支承应力特别是超前支承应力其变化规律不但与诸多地质因素有关外．还随着工作面的推进呈动态变化．在工作面充分采动影响前后其变化规律更是截然不同。利用离散元数值模拟软件UDEC，主要分析了在工作面充分采动前后工作面推进距、埋深、基本顶厚度以及直接顶厚度和硬度等因素对超前支承应力的影响规律．进而得到了工作面充分采动前后超前支承应力的变化规律，为指导采准巷道布置以及科学支护设计提供了可靠的依据。
英文摘要：
The Variation Law of advance support stress is not only related to many geological factors, but also dynamic change with working face advance and especially different before and after sufficient mining. The influence law of advancing distance, mining depth, main roof thickness, hardness and thickness of immediate roof on the advance support stress is analyzed using discrete element numerical simulation software UDEC, the variation law of advance support stress before and after sufficient mining is obtained. The findings are reliable references provided for reasonable layout and supporting design of roadway.
