中文摘要：
针对宽、窄、无煤柱区段巷道防冲存在的问题,提出了沿空巷道外错合理位态减冲设计方法。通过建立覆岩结构模型、底板梁-柱模型,结合现场实测等,分析＂应力场特征-减冲＂关系、＂卸压保护空间尺度-减冲＂关系,揭示了外错布置减冲机理。研究成果在华丰煤矿埋深超千米综放采场实施,确定了外错布置沿空区段巷道的合理位态,同步构建了兼顾顶板治理、支护结构减冲、易发火控制、高效掘进及开采、合理验证与预警的系统关键技术,解决了以往沿空巷道防冲难度大、变形大难以控制、难以实现无煤柱开采等相关工程问题。
英文摘要：
Through the analysis of the problems in rock burst prevention at wide,narrow,no coal pillar section,an opti-mization scheme was proposed that the roadway section near goaf was arranged as outward staggered entries to reducethe danger of rock burst. Based on the model of overlying rock structure,the relationship of ＂low pressure zone and re-duction danger for rock burst＂ and ＂pressure relief protection and reduction danger for rock burst＂ was determined,which revealed the mechanism of preventing rock burst with alternate exterior entry layout pattern. So the reasonableposition,supporting standards and principles were determined. The research findings were then applied in the thickcoal seam with large burial depth（over 1 km） and strong rock burst tendency over the fully-mechanized top-coal ca-ving face at Huafeng coal mine. The study built the key technological system which takes the broken roof control,lia-ble-to-ignition control,efficiency of driving and mining,and reasonable early-warning into consideration. In this way,the prevention difficulty of rock burst and control difficulty of the deformation in roadway driven along next goaf,andthe mining without coal pillar with large burial depth（over a thousand meters） can be realized and solved. The re-search can serve as a reference in similar conditions.
