Mine safety landslide

What should I do if I encounter a landslide? The landslide is usually quite sudden, and the damage caused is difficult to estimate. In the rainy weather, in some of the more humid mountain roads, it is most prone to landslides. Then, what should I do if I encounter landslides? What are the escape skills? Let's take a look.

First, why is there a landslide?

The formation of landslides has both natural and human factors. Natural factors have landform morphology, geological structure, precipitation, groundwater, etc. for man-made factors; human factors include steep slope excavation, blasting effects, and improper soiling. The landslide needs to have a combination of the free surface and various factors to form the sliding surface and the cutting surface, and the sliding force can be reduced when the sliding force is greater than the anti-sliding force. The sliding surface and the shearing surface are often not formed at the same time, but the shearing is first sheared at a point or a local extent, and then gradually developed into a through shear failure surface.

Second, the process of landslides:

The landslide is the slope of the slope rock and soil along the continuous shearing surface. The development of landslides is generally divided into three phases.

1. Creep deformation stage: mainly slow, uniform speed, small amount of subsidence or slip, cracks appear on the slope, and the trailing edge is gradually cracked, which lasts from several days to several decades.

2, the sharp sliding stage: the sliding surface and the cutting surface have been formed, various landslide patterns have appeared one after another, the sliding stage lasts for a short time, generally about a few minutes to tens of minutes, a few meters to tens of meters per minute, even each A few tens of meters.

3. Gradual stabilization stage: Under the effect of self-weight, the landslide body is gradually compacted, the surface crack is closed, the front edge seepage becomes clear, and the sliding body tends to be stable, but in the case of new induced factors, it is deformed again.

3. How to escape when encountering a landslide?

1. When you are unfortunate enough to encounter a landslide, first calm down and don't panic. Panic is not only a waste of time, but also very likely to make a wrong decision.

2. Quickly look around and evacuate to a safer location. In addition to high-speed landslides, as long as the action is rapid, it is possible to escape from the dangerous section. When running away, run to the best direction on both sides. Running up or down in a hill that slides down is dangerous.

3. Never choose the shelter site on the uphill or downhill slope of the landslide. Also don't go through a dangerous area without going through a comprehensive inspection. At the same time, we must follow the unified arrangement and not choose the route.

4. When encountering a high-speed landslide that cannot be escaping, it is even more difficult to panic. Under certain conditions, such as when the landslide is sliding as a whole, it does not move in place, or quickly hugs fixed objects such as trees around it. Can escape under solid obstacles, or kneel in the ground, the trench. Care should be taken to protect the head and wrap your head around your clothes. It is an effective self-rescue measure.

5. In the case of ensuring safety, the closer to the original residence, the better, the better the traffic, water and electricity. Don't run in the direction of the landslide when you flee. Don't be overwhelmed, rolling with the landslide.

6. For the landslide danger zone that has not been slipped, once the suspicious landslide activity is found, it should immediately report the neighboring village, township, county and other relevant governments or units.

7. When landslides, it is very easy to cause personal injury. When injured, you should call for "120". "120" is the telephone number of the national unified emergency center. In the event of major disasters, accidental injuries, serious trauma, acute poisoning, or sudden emergencies, you should immediately call someone to call for "120" while seeking necessary on-site ambulance for the wounded or patient to seek assistance from the emergency center.

4. How to save people who have been buried by landslides?

Experts suggest: How to help people and things buried by landslides to master the correct methods of rescue can quickly save people and things. The essentials are:

Discharge the water at the trailing edge of the landslide body. Excavate from the side of the landslide body. Save people first, then save things.

In addition, after the landslide stops, you should not go home immediately to check the situation. Because the landslide will occur continuously and rush to go home, it will be attacked by the second landslide. Only when the landslide has passed and the house is away from the landslide, confirm that it is safe and secure.
