The filling of highway roadbed in goaf areas of coal mines is difficult,with many risk factors and high requirements for operational technology.Therefore,based on the basic situation of a highway roadbed filling operation project in a coal mine goaf,this paper briefly introduces the highway roadbed filling operation plan in the coal mine goaf,explores the operation steps,and further explores the application effect of filling technology in the foundation treatment of coal mine goaf highways.It is hoped to provide some ref-erence for the practice of highway roadbed filling similar to the remaining surface voids after coal mining.
