In responding to the problems identified, a countermeasure of bolt-mesh-anchor-shotcrete + floor-bolt + truss coupling supporting is proposed, namely using shotcrete to seal surrounding rock, bolt-mesh support to release deformation energy, floor bolt to transfer floor heave plastic slippage force, anchor-truss support to control the deformation of surrounding rock. Therefore, the effective deformation control of deep high stressed soft rock roadway can be achieved.

为此，提出了锚网喷＋锚索＋底角锚杆＋桁架耦合支护对策，即通过喷层封闭围岩，锚网柔性支护释放变形能，底角锚杆转移底臌塑性滑移作用力，锚索＋桁架支护控制围岩整体变形，从而实现对高应力巷道围岩变形的有效控制。
