中文摘要：

为解决某矿单翼开采工作面采掘接替紧张的难题,提出迎采动面掘巷技术。采用数值模拟的方法,分析了某矿4102回风平巷掘进过程中的应力分布和位移场分布规律,得出巷道掘进端头受到的强动压影响范围为距4101工作面-30~+80m。采用分段控制技术,对巷道强动压影响段采取高强大延伸率锚杆和锚索网联合支护、高水材料加固窄煤柱帮、单体支柱和铰接顶梁加强支护顶板,有效控制了迎采巷道围岩变形,确保了工作面的正常接替和安全生产。

英文摘要：

To solve the difficult problems of mining and excavation replacing tension in one-way working face,the technology of roadway driving forward the face was proposed.The numerical calculation was used to analyze the distribution laws of the stress and the displacement field of4102air-return gateway in a mine in the driving process,and it was concluded that the the range affected by the strong dynamic pressure at the heading end of the gateway was-30m to+80m away to4101working face.Sectional control technology was used in the section affected by the strong dynamic pressure,including the combined support with high-strength and large-elongation bolts,cables anchors and wire mesh,the reinforcement of the narrow coal pillar with high moisture material and the roof support by using the individual props and articulated roof beams,which effectively controlled the deformation of the roadway forward the face and ensured the normal replacement and safe production of the working face.
