Abstract: The Jurassic coalfield in Northern Shaanxi is located in a region of China that is ecologically sensitive. Long-term coal mining activities have had a profound impact on the ecology of this area. By monitoring and analyzing the patterns of surface movement, it is possible to assess the extent of the affected areas and the regions that are most severely damaged, thereby formulating targeted remediation measures. This study utilizes actual mining data from a coal mine in Shaanxi to calculate and analyze the specific values of surface subsidence and horizontal displacement, as well as the dynamic and static angular parameters of surface movement. Based on the principle of the probability integration method, probability integration parameters are determined using Matlab for parameter fitting. The findings of this study provide a reference for understanding the patterns of surface movement over shallow coal mines in the Northern Shaanxi region and for the management of the ecological environment.
