深部巷道围岩变形破坏严重，传统支护难以实现巷道围岩有效控制。本文以陶二煤矿新南总回风巷道全断面变形破坏为研究对象，通过现场调研和监测，分析其破坏状况和因素。研究认为巷道全断面变形破坏原因是巷道围岩在高地应力作用下首先发生剪切破坏，而后在高瓦斯压力及水理作用下进一步发生膨胀破碎和蠕变。应用非连续“双壳”围岩控制理论，分析了非连续“双壳”围岩控制机理，构建了“U 型钢(外部应力支护壳体)+柔性垫板(柔性层)+锚杆锚索注浆(内部应力加固壳体)”的非连续“双壳”围岩控制关键技术，取得良好支护效果。

When the deep roadway has been deformed seriously, it is difficult for the traditional sup-port to achieve effective control of roadway surrounding rock. Taking the distortion and breakage of the whole section of the New South total return air roadway of Tao’er coal mine as the research object, the damaged condition and the factors that cause the damage have been analyzed through the field investi-gation and monitoring. The study has shown that the reason of the distortion and breakage of the whole section of roadway is that firstly surrounding rock shear and breakage occurs under the effect of high ground stress, and then the surrounding rock gets further expansion break and creep under the effect of gas pressure and water conditioning. The paper has also analyzed the control mechanism of disconti-nuous “double shell” surrounding rock with the application of discontinuous "double shell" sur-rounding rock control theory. Additionally, this study has helped to build the key technology of the con-trol of discontinuous “double shell” surrounding rock as the U-shaped steel (external stress supports shell)+flexible plate (soft layer)+grouting anchor bars(internal stress reinforces shell), and finally ob-tained good supporting effect.
