Recently, Chongqing Emergency Management Bureau released a survey report on the "6.23" landslide disaster in Wuxi County. 46 on June 23, 2022, a rock landslide occurred in Zhongba Village, Bailu Town, Wuxi County, resulting in two deaths and three missing, with a direct economic loss of about 4.91 million yuan. According to
the survey report, On June 22, 2022, Wuxi Yurui Building Materials Co., Ltd. received a notice from Zhongba Village, Bailu Town, requesting the evacuation of all personnel from the sand mining plant, a notice from the Fifth Company of the Fifteenth Bureau of China Railway requesting the evacuation of all personnel within the scope of the warning line, and a notice from the Fifth Company of the Fifteenth Bureau of China Railway requesting the evacuation of all personnel within the scope of the expanded warning line. The evacuation of personnel has not been organized as required and the operation has not been continued.
The investigation confirmed that the landslide disaster was caused by natural factors, rainfall and human engineering activities. Through the analysis of disaster occurrence and formation reasons, the favorable terrain conditions and slippery geological structure are the internal factors of the landslide, and the rainstorm and slope cutting excavation at the foot of the slope are the external factors of the landslide, which cause the landslide geological disaster under the combined action of internal and external factors.
The investigation report shows that the disaster has exposed such problems as insufficient awareness and awareness of local geological hazards, incomplete investigation of hidden geological hazards, and inaccurate early warning and prediction of geological hazards. In addition, in the course of the investigation, the investigation team also found such problems as illegal operation, illegal soil extraction, untimely transfer of personnel to avoid danger, interruption of danger information reporting, and negligence of daily supervision. Relevant local governments and departments are responsible for the casualties caused by the landslide disaster.

accident case
Time: May 16
, 2021 Location: a mountain collapse accident occurred at a construction site in Jishou City
, Hunan Province, killing three people. The accident investigation report showed that the local rainstorm had been falling at the time of the accident, and the construction unit had been in a state of shutdown after receiving the warning. On May 16, three workers went to the mountain to pick fir fungi, and a few minutes later, the mountain collapsed.
Among the causes of the accident, it can be seen that although the construction unit has taken measures such as modifying the access road, closing the hidden danger area, posting warning signs, and carrying out technical and safety disclosure of the hidden danger of slope safety for the construction personnel, the closure is not thorough, and the management of workers is not in place, resulting in workers entering the hidden danger area without authorization.
Summary: Although the construction unit has done the preventive work, the management workers are not in place, resulting in the failure of the preventive work. Workers'own weak awareness of risk avoidance, in turn, shows that the construction unit has not been trained in place, only pays attention to the "hard" control in the work, and neglects the "soft" education of workers' thoughts, which leads to tragedy. Successful Case of
Risk Avoidance Date: February 9
, 2022 Location: Chagou Village
, Lingquan Town, Shilou County, Shanxi Province At about 9 o'clock on February 9, Chagou Village inspected the landslide hazard on the west side of Shanxi Shude Agricultural Science and Technology Co., Ltd. If there are signs of falling and sliding on the mountain, report them in time. The local government immediately organized the evacuation of more than 50 workers from the company's workshop under the slope. At about 11:50, a landslide occurred and the Linshan workshop was knocked down. Due to timely warning and early evacuation, no casualties were caused.
Summary: One month before the occurrence of the disaster, the relevant departments and units investigated the hidden danger point of the disaster, considered that the hidden danger point had a very high risk of the disaster, and formulated a disaster prevention plan and monitoring plan. The inspection cycle is encrypted from seven days to one day, which gains time for timely detection of signs of disaster body deformation and efficient disaster disposal.
