Abstract: In order to ensure the safety of the expressway on the old goaf and to standardize the operation process of the safety evaluation of the expressway construction on the old goaf,a general procedure for the safety evaluation of the expressway on the old goaf of coal mine was put forward.Also a detailed summary and analysis of the commonly used methods for evaluating the construction of expressway on the old goaf of coal mine was given,which provides a theoretical basis for the selection of safety evaluation methods.After analyzing the governance countermeasures of the expressway on the old goaf,it was pointed out that the grouting filling is not necessarily the best way to control the old goaf in the coal mine.The appropriate old goaf management program and highway pavement design countermeasures should be selected by combining with the results of the determination of the stability of the old goaf.The research results provide a technical reference for the safety evaluation of freeway passing through the old goaf of coal mine.
