A sudden landslide in Jincheng, Shanxi Province caused a coal miner to be buried on a slope. What happened next? After this incident, the Shanxi Provincial Emergency Management Department has urgently requested all localities to carry out safety hazard inspections on ground buildings and conduct If safety hazards such as insufficient safety distances, steep slopes, loose soil, or large water collection are found in residential areas, the residents must be evacuated immediately to ensure safety.
According to relevant information, Podi Coal Mine is an infrastructure mine. According to the Shanxi Province Coal Mine Grading and Classification Supervision Methods, coal mine safety assurance levels are divided into categories A to D from high to low, and this coal mine belongs to Category B coal mines. The incident occurred at 4:23 on August 5. A landslide occurred in Podi Village, Jincheng City, burying three construction workers at the Jinsheng Podi Coal Mine of Shanxi Jincheng Coal Group.
For landslides, the most serious thing is landslide cracks, which refer to a series of cracks produced in the landslide body and its edges during landslide activity. Those located in the upper part of the landslide body, which are mostly arc-shaped, are called tensile cracks; those located on both sides of the middle part of the landslide body, at the boundary between the sliding body and the non-sliding body, are called shear cracks; both sides of the shear cracks are often accompanied by feather-like arrangements. Cracks, called feathery cracks.
Recently, landslides have also occurred in Kunshan City. At 5:30 in the morning, a landslide occurred on the mountain behind the Kunming Power Plant in Chejiabi, the district, killing one person. After receiving the report, leaders of the Xishan District Party Committee and District Government rushed to the scene to direct the rescue and disposal. Public security, emergency response, firefighting, traffic police, natural resources, transportation, streets and other departments worked together to provide full rescue. After on-site investigation, it was found that the landslide covered an area of about 86 square meters and one person was trapped. After an all-out search, the trapped persons were found, but the 120 medical emergency department confirmed that they had no vital signs.
Currently, because of the heavy rainfall recently, landslides have occurred. For landslides, some landslides occur slightly later than the triggering factors. Such as after rainfall, snowmelt, tsunami, storm surge and human activities. This hysteresis pattern is most obvious in rainfall-induced landslides, which often occur after heavy rain, heavy rain, and long-term continuous rainfall. The length of the lag time is related to the lithology and structure of the landslide body and the amount of rainfall. . Generally speaking, the looser the landslide body, the more developed the cracks, and the greater the rainfall, the shorter the lag time.
Generally speaking, landslides that occur after manual excavation of the slope foot, pile loading, reservoir storage, and water release also fall into this category. The length of the lag time of landslides induced by human activity factors is related to the intensity of human activities and the original stability of the landslide. The greater the intensity of human activities and the lower the stability of landslide rescue landslides, the shorter the lag time will be.
Summary: A sudden landslide in Jincheng, Shanxi Province caused coal miners to be buried on a slope. What happened next? After this incident, the Shanxi Provincial Emergency Management Department has urgently requested all localities to conduct safety hazard inspections on ground buildings. , if safety hazards such as insufficient safety distance, steep slopes, loose soil, or large water collection are found in residential areas, the residents must be evacuated immediately to ensure personnel safety.
