摘　　要：采用极限平衡理论和数值模拟方法对综采工作面沿空掘巷窄煤柱合理宽度进行了分析。依据不同宽度的窄煤柱与巷道围岩变形量的关系,确定了合理的窄煤柱宽度,并应用于工程实践。实践结果表明研究确定的窄煤柱宽度合理、技术和经济效益显著,对类似条件下综采工作面沿空掘巷窄煤柱合理宽度的确定有一定的指导意义。The limit balance theory and numerical simulation method were applied to analyze the rational width of the narrow coal pillar for the gateway driving along the goaf of the fully mechanized coal mining face.According to the relationship between the different width narrow coal pillars and the surrounding rock deformation value of the mine gateway,the rational width of the coal pillar was set up and was applied to the engineering practices.The practice results showed that the narrow coal pillar width studied and set was rational and the technical and economic results were obvious.The practical results could provide the certain guidance to set the rational width of the narrow coal pillar for the gateway driving along the goaf of the fully mechanized coal mining face under the similar conditions.
