摘　　要：银西铁路穿越彬长矿区,为确保线路方案选择及后期的安全运营,需对矿区采空区地表变形进行研究和分析,对其稳定性作出合理评价。通过对彬长矿区采空区特征的研究,地表变形的理论分析、计算,结合现场的变形监测数据,得出了采空区地表会产生弯曲型下沉盆地,采空区及采空区影响范围内会发生不同程度的下沉和变形的结论,并根据矿区地质选线的原则,确定了线路方案。Because Yinchuan-Xi'an Railway crosses the goaf of Binchang coal mine,the ground deformation of the goaf of the coal mine needs to be researched and analyzed,and its stability should be evaluated reasonably in order to ensure the safety of route selection as well as later operation.By means of the characteristic research,theoretical analysis and calculation to the ground deformation of the goaf of Binchang coal mine,combining with on-site deformation monitoring data,the article concludes that the ground at the goaf may form a bending-type sinking basin,and the goaf and its effected area may have the different levels of subsidences and deformations.Finally,according to the principle of geological route selection at mining area,the railway route scheme is determined.
