Accident liability analysis
In this accident, Sanhe Shunxun Coal Mine was mainly responsible for the accident. This coal mine can be described as a problem coal mine.

It can be seen that it is a matter of time before an accident occurs in such a coal mine. Although the local leaders conducted two safety inspections on the coal mine, the inspections were not strong enough, and all potential safety hazards were not eliminated. The accident was also related to poor safety supervision.
How to avoid roof caving in coal mine
The main cause of the accident is roof collapse, so it is necessary to avoid coal mine collapse. First of all, in the early stage of mining, reasonable calculation, design and layout should be carried out, and mining should be carried out within the designed scope. It is necessary to do a good job of roof protection when mining under special geological conditions such as faults and wind-blown oxidation zones. In order to avoid accidents, coal mines with backward construction technology and facilities need to be rectified or eliminated.
