Abstract: Based on the engineering background of the excavation through DWF10 fault fracture zone of northwest upper-roadway for transportation, the paper synthesized numerical calculation and field industrial test to study the controlling technologies and countermeasures of roadway surrounding rock in fault fracture zone. The results of numerical calculation indicated that: (1)after roadway excavation, the roadway surrounding rock damaged rapidly along the fault; (2) Obviously asymmetric characteristics be fund in both the deformation of roadway surrounding rock and the plastic zone distribution, and the deformation of hanging wall side of roadway significantly less than which of footwall side, the amount of floor heave dramatically greater than that of floor sag, and the plastic zone of surrounding rock near the fault fracture zone is significantly larger than any other places; (3) Because the different weakening effects of fault fracture zone, the stress decreasing range is relatively big in terms of the hanging wall side of roadway and roadway floor. Then, the paper put forward the solutions of support——“high pre-stressed anchor and net support + u-shape steel support + concrete support” as the first support, and “pre-stressed anchor cable support + lagging grouting reinforcement” as the second support. The supporting effect indicated that the surrounding rock has been under control basically, that is mean that the roadway excavation in thin-coal seam close to big fault for decreasing coal reserves under the mining roadway and increasing coal recovery rate can be achieved.
