Adjusting the rescue plan to avoid the impact of secondary disasters in an open-pit coal mine collapse accident in Alxa Left Banner, Inner Mongolia

　　At about 13:00 on February 22, an open-pit coal mine of Alxa Left Banner Xinjing Coal Industry Co., Ltd., Alxa League, Inner Mongolia collapsed.

The reporter learned from the Inner Mongolia Alxa League Rescue Headquarters that as of 22:30 on the 23rd, the accident had killed 6 people, injured 6 people, and 47 people were still missing.

　　Headquarters reporter Niu Qiaogang: This is the core area of ​​the collapse accident, and the rescue work on the scene is currently being carried out intensely and orderly.

We can see that the collapsed area is relatively large. According to calculations, the volume of the collapsed earthwork reached 10 million cubic meters, which also caused great difficulties for the rescue work.

　　After the accident, the national emergency management department dispatched rescue experts and local support forces, expert teams, professional teams, and medical resources to the rescue site one after another.

Due to the large volume of collapse in the accident area, the risk of secondary collapse during mechanical operations is high, which seriously affects the progress of rescue work.

At 18:44 on the 22nd, another relatively large landslide occurred in the collapsed area, which put the rescue work in trouble.

　　Li Zhongzeng, head of the Alxa League in Inner Mongolia: This time, there was a large landslide on the mountain, and the amount of landslides collapsed was relatively large, so rescue was indeed very difficult.

Rescue forces from all sides, including those from surrounding areas, are rushing to the scene one after another.

　　To this end, the rescue department changed the rescue plan, adopted layered excavation and trapezoidal descending methods, and carried out excavation and search and rescue work from both sides of the mountain to ensure the stability of the mountain and the safety of trapped people and rescuers to the greatest extent, and avoid the impact of secondary disasters.

Up to now, rescue and disposal work is in progress.
