摘　　要：采空区不良地质问题影响铁路工程地质选线和运营安全,并且规模越来越大。通过几十年来铁路工程积累的经验,提出不同等级的铁路适应地表和岩层变形的能力不一样,塌陷角的选择和保护煤柱的宽度也不同,高速铁路应该留设更宽的安全煤柱。The unfavorable geological condition threatened the railway safety and rail track selection and the size of gob was more and more bigger.Through many years of experience in railway engineering,it is realized that the adaptability for ground surface and terrane deformation was different for different grade railway.Be- sides,the selection of collapse angle and the width of protection coal wedge were also different.The broader coaX wedge should be retained for high-speed railway.

关 键 词：采空区 工程地质选线 地表变形
