随着开采深度的增大，深部巷道在复杂高应力场的作用下，表现出严重底鼓和顶板下沉等软岩大变形破坏现象，沈北矿区清水矿深部软岩巷道变形破坏尤其严重。本文通过对地层岩性和地应力场分布规律等的研究，得出了传统支护条件下深部软岩巷道产生大变形破坏的原因和机理，提出了通过恒阻伸长吸收变形能、控制围岩变形为核心，以恒阻大变形锚杆耦合支护为主体的深部软岩控制对策，现场应用效果良好，为深部软岩大变形巷道支护提供了新的方法。

With mining depth increasing, deep roadways emerge serious floor heave and roof conver-gence by complex stress field. Softrock roadways deformation of Qingshui Coal Mine is the most severe in Shenbei Mining Area. By researching on lithology and stress field, the paper draws reasons and fail-ure mechanism of the typical roadway which use the traditional supporting methods. The deep soft rock supporting technology which is constant resistance large deformation bolt coupling technology was put forward. The technology control roadway deformation by constant resistance and energy absorption. The support method works well on site which provides a new way of control deep soft rock roadway large deformation.
