accidents. higher health unsurance, health costs, poor ventilation, toxic gas, lung cancer, asbestos, fires, explosions

environmental impacts

rainwater leaking into abandoned mining it mixes with pyrite forms sulfuric acid and makes the water acidic along with spreading toxic metals

methan release
