中文摘要：

随着矿井开采向深部延伸,工程地质环境日趋复杂,使得深部煤巷支护愈加困难,为了更好地解决深部综放沿空掘巷的支护问题,在地应力测试和岩石力学试验的基础上,分析了深部综放沿空掘巷变形机理,并针对其破坏特征,通过数值计算、理论与工程类比相结合的研究方法,确定了掘巷留设窄煤柱的合理宽度、支护方案和参数,工程应用效果表明,这种综合研究方法有效地控制了沿空掘巷围岩的变形问题,为控制深部复杂高应力综放沿空掘巷变形提供了理论依据与技术途径。

英文摘要：

As the extension of mining and increasing complexity of engineering geological environment,supporting is more and more difficult.In order to better address the deep caving driving gob of supporting issues,on the basis of the stress test and rock mechanics testing,analyzed the deformation mechanism of caving along goaf,and by numerical calculation,the combination of theory and engineering research methods analogy,determined the reasonable width of the narrow pillars,supporting programs and parameters.Engineering results show,the integrated research approach controlled the driving gob-rock deformation effectively,and provide a theoretical basis and technical approach.
