近年来,煤炭的大规模开采使矿山周围形成很多采沉区,沉陷造成了土地和道路塌陷、房屋变形等,同时,也致使铺设在沉陷区上方的铁路线路随着地表一起下沉,线路几何尺寸发生严重变形,对行车安全构成了严重威胁,因此,有效治理煤矿铁路沉区,是提升矿区铁路安全行车、提高运量的根本之路。 In recent years, the large-scale mining of coal has led to the formation of many mining and deposition areas around the mines. The subsidence has caused the collapse of land and roads, the deformation of houses and the like. At the same time, the railway lines laid above the subsidence areas have sunk along with the surface, The serious deformation of the dimensions poses a serious threat to traffic safety. Therefore, effectively controlling the subsidence area of ​​the railway is a fundamental way to enhance safe driving and increase traffic volume in the mining area.
