Hunan Anhua non -natural earthquake incident, checked

At 15:20 on September 17th, a non -natural earthquake incident in Xiang'an tungsten industry, which is located in Xiang'an Tungsten in Yanxi Town, Anhua County, Yiyang, Hunan, Hunan, Hunan, Hunan, Yiyang County, Yiyang County, Yiyang County, Yiyang County.

At 15:20 on September 17th, a non -natural earthquake incident that was equivalent to a magnitude 3.0 earthquake in Xiang'an Tung Tung Tung Tall, which is located in Xixi Town, Anhua County. By preliminary verification by the China Earthquake Network Center and the Hunan Earthquake Administration, the earthquake incident was collapsed. The Anhua County Party Committee and County Government immediately launched an emergency plan, organizing emergency, fire protection and other departments to the scene to deal with. At the same time, the Municipal Emergency Bureau and the Municipal Earthquake Bureau have rushed to the scene.

This collapse was caused by regional rush in the old -fashioned area of ​​Xiang'an tungsten industry. It is understood that on September 16, the safety management personnel of Xiang'an tungsten industry found that during the inspection of the underground inspections, they found that the top plate and ore pillar of the old air zone in the upper part of the upper part were compressed and cracking. Discontinue production.

There were no casualties in this incident, no one under the well was trapped, and the surface structure was normal. At present, all personnel in the hazardous area have been evacuated, controlled the dangerous areas, and organized relevant experts to comprehensively evaluate the area.

Small knowledge of the earthquake: What is a collapse earthquake?

The collapse earthquake means that the earthquake caused by the collapse of the underground cave or the top of the mine is called a collapse earthquake. The scale of this type of earthquake is relatively small, the destructive is relatively small, and the number of times is very small. Generally, it occurs in the limestone areas or large -scale underground mining areas. The collapse earthquake is generally around 3.

What are the preventive measures for the collapse earthquake?

1. For areas that have collapsed on the ground and have poor stability, and there are still signs of activities, we should resolutely avoid it and cannot be used as a residential place of residential residence and important construction equipment factories, highways and other construction land.

2. In the mining area mining under the well, a protective mine column should be set up, that is, a sufficient size of mineral columns are left in the lower part of the objects that need to be protected, so that the building is outside Panel, strip -based mining, coordinated mining and other methods to prevent or slow down the occurrence of ground collapse.

3. Do a good job of monitoring of ground collapse disasters. The purpose of monitoring is to propose alert before collapse in order to take measures in time. Monitoring mainly includes: long -term observation (including ground buildings, dynamic observations of various water points), ground level and seismic monitoring, and diamond -exploitable layered stump monitoring.

How to monitor the collapse earthquake? Early warning system issued warnings to tens of millions of people's TV and mobile phones

"Earthquake early warning" refers to the principle of using a radio wave ratio earthquake to provide a few seconds to tens of seconds to the target area before the earthquake is under damage to its surrounding target areas. During this time, residents can be quickly found at home.

The mainland earthquake early warning network has successfully warned 73 destructive earthquake 73 times

Public information shows that the mainland earthquake early warning network jointly built by the Chengdu High -tech Disaster Reduction Research Institute has covered 2.4 million square kilometers, accounting for 90 % of my country's densely populated multi -earthquake area, and has been successfully warned 73 times. Destroyed earthquakes, including the 7 magnitude earthquake in Lushan in Sichuan in 2013, a magnitude 6.5 earthquake in Ludian in Yunnan in 2014, a magnitude 7.0 earthquake in Jiuzhaigou in 2017, and a magnitude 6.0 earthquake in Changning, Sichuan on June 17, 2019.
