【Abstract】 It was paradoxical between expressway maintaining and underground coal mining under expressway.Fist,the damage of subsidence to expressway was represented,on basis of properties and hazard of surface deformation caused by coal mining.Then research status in China and foreign of expressway mining damage and feasibility methods of goaf management under of approach to expressway were introduced.The examples that put forward grouting technique to disposal mined-up region as the expressway across were mainly emphasized.At last,it pointed out mining under expressway which do not damage the expressway can implement,as long as the measures were correct(at present it mainly was grouting),according to analysis and generalization the related theoretical research and practical successful experiences.更多还原
