It is normal for coal miners to have a dark nose when taking a shower after work.

Working in a dusty environment will definitely have an impact on the lungs, but as long as it is coal, it is easy to digest.

I am a pioneer. I touch more rocks than coal. It is necessary to wear a dust mask. Try to breathe less.

What you are looking at is the substation on the electromechanical front, and you will not stay in a dusty environment for a long time. The problem is not big at all.

Remember to wear a mask at work, and pay attention to eating more lung-clearing foods such as fungus and pears in your diet.

Coal mining is a high-risk industry. After all, our income is higher than other industries, and it is inevitable to make some sacrifices. Just relax.

Finally, I wish you a happy work, and it is most important to keep an open-minded mood every day!
