Abstract: As an important energy base, Ordos is part of the Loess Plateau and has a very fragile ecosystem. A large number of open-pit mines, spoil heaps and subsidence areas have been created with the large-scale coal mining. Chuancaogedan coal mine in Zhungeer Banner was selected as the research object to study the natural restoration effect and methods of collapse fractures in the coal underground mining-induced subsidence areas in loess hilly and gully region. Remote sensing interpretation, soil measurement and other means were used to construct a natural recovery model of edge cracks, based on revised universal soil loss equation (RUSLE). The natural restoration characteristics of collapse fractures were studied and restoration suggestions were put forward. The results show that the collapse areas in loess hilly and gully region have zonal characteristics. The dynamic fractures area could basically recover within one year under natural restoration, and the restoration effect is good. The natural restoration effect of the edge crack area is poor and it is difficult to recover for a long time, with the longest simulated restoration time reaching 26.2 years. The research shows that the restoration of collapse areas should adopt a nature-based zonal restoration method. The research results could provide references for the restoration and governance of collapse fractures caused by underground mining in loess hilly and gully region.
