摘　　要：某铁路沿线煤炭资源广泛分布,采空区大范围存在,其中新建A站至新建B站段地质条件最为复杂,本文重点对该段线位进行比选。通过资料搜集、现场调查走访、物探探查、InSAR沉降分析、采空区影响宽度计算等综合勘察方法,查明了研究区开采现状及采空区的工程地质特征,从工程地质条件、煤矿压覆、工程投资,并结合煤矿开采规划,对各方案进行综合比选,提出了推荐方案。Coal resources are widely distributed along a railway,and the goaf region exists in a large area,among which,the geological conditions from new railway station A to station B are the most complex.This paper focuses on the comparison and selection of the line position of this section.Through data collection,on-site investigation,geophysical exploration,InSAR settlement analysis,calculation of inuence width of goaf and other comprehensive investigation methods,the mining status and engineering geological characteristics of goaf in the study area are identified,furthermore,comprehensive comparison with each other of various schemes were carried out in termscondition of engineering geological conditions,coal mine overburden,engineering investment and combined with coal mining planning,and the recommended scheme is put forward.
