Abstract	It is of challenge and emergent problems for hazardous assessment and treatment technology for the mined-out regions under highway. Based on MC6 mined-out regions under Yangquan-Yuxian highway which is in Shanxi province, the three-dimensional engineering geological model and computational model have been built by using the coupling modeling method with $MIDAS/GTS-FLAC^{3D};$ and then numerical analyses are performed with $FLAC^{3D},$ which reflecting the work conditions of mining coal in MC6, grouting treatment to the mined-out regions and construction of roadbed with filling and excavation. The surface deformations under different conditions have been revealed, the ground subsidence basin characteristics and the subsidence centre position have been determined, and the deformation trend of ground subsidence monitoring points has also been predicted. The above-mentioned results were successfully applied to guiding the practice of reinforcement grouting key parts of mined-out regions, obtaining a notable technical and economic effect, which will offer a practical reference for similar projects.
