As recently as the last few decades, thousands of miners died in explosions, roof collapses, fires, and floods each year, and lung disease caused by inhaling mineral dusts was ubiquitous. Miners worked virtually unprotected, and were often treated as expendable bodies fulfilling critical roles in this important industry, which in the United States comprises about 5% of the gross domestic product.
就在过去几十年间，每年都有数千名矿工死于爆炸、顶板坍塌、火灾和洪水，因吸入矿物粉尘导致的肺病也很常见。矿工们工作时几乎毫无防护，在这个对美国国内生产总值贡献约5%的重要产业中，他们常被视为可牺牲的劳动力，承担着关键角色。
