摘　　要：根据采空区移动盆地地表变形判据,结合不同等级铁路的竖曲线、倾斜及工后沉降控制标准,对控制大面积采空区工程地质选线原则的岩移角选择问题进行了深入探讨。研究表明对于大面积采空区段:高速铁路应采用边界角开展地质选线,200 km/h客货共线铁路、重载铁路与国家Ⅰ级~Ⅳ级铁路可采用相应的临界岩移角。According to the surface deformation criterion of gob mobile basin, combined with the vertical curve, inclination and post construction settlement control standards of different grades of railway, the selection of rock movement angle to control the engineering geological route selection principle of large-area gob is deeply discussed. The research shows that for large-area mined out area: high-speed railway should adopt boundary angle to carry out geological route selection, 200 km/h mixed passenger and freight railway, heavy haul railway and national grade Ⅰ~Ⅳ railway can adopt corresponding critical rock movement angle.
