An accident occurred in a coal mine in Qinyuan County, Shanxi Province, and five people were trapped. What are the risks of mining?

Mining is a dangerous job, which is harmful to health for a long time. In my opinion, there are three main risks in the process of mining. The first is gas explosion, the second is mine collapse, and the third is undercurrent surging. Once these three risks appear, they will endanger the life safety of underground workers.

An accident occurred in a coal mine in Qinyuan County, Shanxi Province, causing five people to be trapped underground. Sadly, the five trapped miners lost their vital signs when they were found by rescuers. Similar things happen from time to time in mines, and because of this, this job brings high income and great risks.

Risk 1: Mine collapse, whether it is ore mining or coal mining, needs to go deep underground. In this case, the safety of underground workers will not be fully guaranteed. Although the supporting structure has been completed and the safe passage has been reserved, accidents often occur and are very serious.

If the mine collapses, the miners may be buried directly. If we are lucky, we will leave appropriate space for the miners to wait for rescue in the underground. Even if it is not buried alive, the collapse will narrow the underground space and make the air thinner, which will be life-threatening for a long time.

Risk 2: The temperature in the gas explosion mine is higher than the outside, and there may be flammable and explosive gases. Some mine accidents are caused by gas being ignited and eventually exploding in a narrow space.

After the explosion accident, it will directly threaten the life safety of underground workers. Serious accidents will kill workers on the spot, but not serious accidents, it will also make the mine cave collapse, and then make workers trapped underground.

There are many unknown risks underground, besides collapse and gas, there may be underground rivers. Once encountering an underground river, the water level in the mine will rise sharply, which is also a potential risk for underground workers.
