Abstract: The main types of geological hazards in Xuzhou City are rockfall, ground collapse and ground subsidence, due to the exploitation of mineral resource and groundwater for a long time. In order to find out the characteristics, developing trend and threat degree of geological disasters in Xuzhou City, and provide better guidance for the prevention and control of geological disasters, based on city geological survey and mine geological environment survey in Xuzhou City, the authors summarized the types of various geological hazards, through referring to the investigation and prevention work of geological hazards in Xuzhou City in recent years. The formation mechanism and temporal distribution of various geological hazards in Xuzhou City were also investigated. The developing trend of various geological hazards were predicted based on the geological environment conditions, and the corresponding prevention measures were put forward. At present, the prevention and control work of geological hazards in Xuzhou City has achieved certain results, which can provide some reference for the prevention work of geological hazards in other regions.
