摘　　要：通过分析既有资料并与实际工作案例验证相结合,梳理出采空区铁路选线野外地质调查评价具体工作方法,理清重点问题及解决对策。该方法在实际案例中有较好的实用性;应重视在采空区铁路选线中野外地质调查的重要作用。建议矿产资源丰富地区交通工程地质选线工作前移至区域路网规划阶段,提高综合效益。By combining existing data analysis with actual work case for verification,the detailed working methods of field geological survey and evaluation for railway route selection in mined-out areas was put in order,and the key problems and solutions were clarified.The method has good practicability in actual cases,and field geological survey should be paid attention to in railway route selection in mined-out areas.It is suggested to arrange geological route selection of traffic engineering in the areas with rich mineral resources in the earlier stage of regional road network planning for the purpose of increasing comprehensive benefit.
