Stability Evaluation of Underground Goaf in Reconstruction and Expansion Project of Jinyang Expressway

晋阳高速改扩建工程位于山西省晋城市阳城县境内,部分区段穿越煤矿采空区,准确评价采空区稳定性对穿越采空区路段防灾减灾十分重要。在充分查明沿线采空区地质条件和要素特征的基础上,根据采空区类型对采空区场地进行了稳定性评价,并结合工程类型的重要性等级提出了处治建议。

The reconstruction and expansion project of Jinyang expressway is located in Yangcheng county, Jincheng city, Shanxi province. Some sections pass through the goaf of coal mine. The accurate evaluation of the goaf stability is very important for disaster prevention and reduction of the sections passing through the goaf. On the basis of fully identifying the geological conditions and element characteristics of the goaf along the line, the stability of the goaf site is evaluated according to the type of goaf, and the treatment suggestions are put forward in combination with the importance level of the project type.
