After a major landslide disaster occurred in the Wuzhou vanadium mine in Sanyang, Shaanxi, the Xi'an Land and Resources Bureau immediately arranged the deployment of mine geological hazards in the whole system. In this investigation, the Xi'an Municipal Bureau of Land and Resources used the aerial survey of drones for the first time to investigate the geological hazard points quickly and comprehensively. On August 15th, the geological hazard investigation team dispatched by the Xi'an Municipal Bureau of Land and Resources conducted a geological hazard investigation at the Jiaochanggou limestone mine in Hu County. The teaching field ditch is a hidden danger point of large mudslides, which directly threatens the safety of the West Han Expressway. In the past, when investigating the source area of ​​the trailing edge of the debris flow, it was difficult for the investigators to fully grasp the hidden dangers because the investigators could not reach the steep mountainous areas. In this regard, the Xi'an Municipal Bureau of Land and Resources used the aerial survey of drones for the first time. Through aerial photography, it was found that the rock mass at the trailing edge of the debris flow was broken and the source of the material was abundant. It was concluded that the hidden danger of the debris flow was still in a state of poor stability. The Municipal Bureau of Land and Resources Bureau has recommended that the Huxian County Land and Resources Bureau strengthen monitoring, entrust professional units to prepare management plans as soon as possible, and report to the county government to raise funds to implement the governance project. In this investigation, the Xi'an Municipal Bureau of Land and Resources requested the relevant units and departments to immediately carry out the investigation of hidden dangers of mine geological disasters, focusing on the investigation of whether there are hidden dangers of geological disasters in the mining operation area and living area, the stability status of hidden danger points, and the mines. Whether the responsibility for the prevention and control of geological disasters in enterprises is implemented or not; the second is to supervise the mining enterprises to do a good job in prevention and control of geological disasters, to ensure that the responsibility for prevention and control of geological disasters within the mine production and living areas and various preventive measures are in place; and third, to do a good job in information reporting and emergency response. Work, found that mining activities have caused serious geological disasters, we must order mining enterprises to immediately stop production, evacuate personnel in a timely manner, and implement monitoring personnel to do monitoring and prevention work to avoid casualties. It is reported that Xi'an Municipal Bureau of Land and Resources has transferred more than 60 people from government agencies and institutions, and divided them into seven inspection teams. They have gone to key districts and counties to carry out inspections on hidden dangers of mine geological disasters and 595 geological hazards in the city. In the past three days, the city's land and resources system has dispatched 729 cadres and workers and 168 vehicles, and investigated 535 hidden danger points, 18 construction sites, 10 mines and 39 brick factories.
