2019-12-24Welcome back to the surface mining model. In the previous topic, we learned about different types of surface mining operations, about equipment, about different methods that are commonly used to extract coal or different ore deposits. Its not difficult to understand that mining is one of the most dangerous working environments in the world and in this topic, we will go through some of the ...
Surface mining also contributes to air pollution through the release of toxic compounds. These particulates react with water vapor to produce acid rain. Surface coal mining, for example, has contaminated more than 5,000 miles of streams in the eastern United States, impacting aquatic ecosystems and public drinking water supplies.
Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
