Why do we say Hume miners?

My second uncle has been working in a mine in the United States for more than three years. He spends half of a month working hundreds of meters underground in the mine. That time I had a video call with my second uncle: After some pleasantries , I advised my second uncle that it was too dangerous to be a miner, and I should change jobs after making a few more years of money. The second uncle laughed after hearing this: You may not believe it. Mining is a very popular profession in the United States. Many people want to engage in this industry. The actual income after excluding pensions and federal tax deductions can reach 110,000 per year. dollars, and of course there are scattered other benefits. The problem is that being a miner in the United States is very safe, and the incidence of occupational accidents is as low as that of warehouse keeping.

I was extremely surprised when I heard that. Although I had never heard of any mining accidents in the United States, it was impossible to exaggerate. Later, I followed the instructions of my second uncle and logged in to the official website of the United States Department of Labor. , I realized that this turned out to be true. I curiously asked my second uncle how the United States did it. My second uncle smiled slightly: In fact, it took decades to reach this point. I will share it below. The second uncle's narration of the ins and outs of the American miner's career.
