What happened to the sudden landslide in Jincheng, Shanxi, which led to the burial of coal miners on sloping fields?

A sudden landslide occurred in Jincheng, Shanxi Province, which caused the coal miners on the slope to be buried. What happened next? After the incident, the Shanxi Provincial Emergency Management Department has urgently requested all localities to do a good job in the investigation of hidden dangers of ground buildings. If there are hidden dangers such as insufficient safety distance, large slope, loose soil and large catchment in residential areas, residents should be evacuated immediately to ensure safety.

According to the relevant information, Podi Coal Mine is a capital mine. According to the classification supervision method of coal mines in Shanxi Province, the degree of coal mine safety guarantee is divided into A to D from high to low, and coal mines belong to Class B coal mines. The incident occurred at 4: 23 on August 5, when a landslide occurred in Podi Village, Jincheng City, causing three construction workers in Jinshengpodi Coal Mine of Shanxi Jinmei Group to be buried.

For landslide, the most serious is landslide crack, which refers to a series of cracks produced by sliding body and its edge during landslide activity. Those located in the upper part of the landslide and spreading in an arc are called tensile cracks; Located on both sides of the middle part of the sliding body, the boundary between the sliding body and the non-sliding body is called shear crack; Shear cracks are often accompanied by pinnate cracks on both sides, which are called pinnate cracks.

Recently, a landslide occurred in Kunshan City. At 5: 30 in the morning, a landslide occurred in the back mountain of Chejiabi Kunming Power Plant, which has caused 1 person to die. At that time, after receiving the report, the leaders of Xishan District Committee and District Government immediately rushed to the scene to direct the rescue and disposal, and the public security, emergency, fire protection, traffic police, natural resources, transportation, streets and other departments cooperated in the rescue. After field investigation, the buried area of landslide is about 86 square meters, and 1 person is trapped. After full search, the trapped person was found, but confirmed by 120 medical emergency department, there was no vital sign.

At present, landslides have occurred because of the recent heavy rainfall. For landslides, some landslides occur later than the inducing factors. Such as rainfall, snowmelt, tsunami, storm surge and after human activities. This lag law is most obvious in rainfall-induced landslides, which mostly occur after heavy rain, heavy rain and long-term continuous rainfall. The lag time is related to the lithology, structure and rainfall of the landslide. Generally speaking, the looser the landslide, the more developed the cracks, the greater the rainfall and the shorter the lag time.

Generally speaking, landslides caused by artificial excavation at the foot of slope, accumulation and reservoir water storage and drainage also belong to this category. The lag time of landslide induced by human activities is related to the intensity of human activities and the original stability of landslide. The greater the intensity of human activities, the lower the stability of landslide rescue and the shorter the lag time.

Summary: A sudden landslide in Jincheng, Shanxi Province caused coal miners to be buried on the slope. What happened afterwards? After the incident, the Shanxi Provincial Emergency Management Department has urgently requested all localities to do a good job in the investigation of hidden dangers of ground buildings. If there are safety hazards such as insufficient safety distance, large slope, loose soil and large catchment, the residents should be evacuated immediately to ensure their safety.
