treacherous conditions. "Coal-cutting" machines were introduced in the 1880s. By 1912, surface mining was performed by using steam shovels designed for coal mining. Safety Mining underground certainly poses some major health risks to workers, but today's workers have highly advanced equipment that protects them in dangerous scenarios.
COAL MINING AND PROCESSING METHODS A modern coal mine is a highly mechanized industrial plant that has to meet strict standards of engineering design and operation. The size, power, strength, monitoring and control features, and automation of mining equipment dwarf TABLE 4.1 U.S. Top Coal Producing States in 2005 those of even a few decades ago.

Voltaire's words echo through every mining operation, as dangers and hazards are present at all times. From explosions, to harsh chemicals and dust, miners know that hazards will soon come their way. Mining ranks as one of the top dangerous US industries, specifically underground coal mining.
coal mining - coal mining - Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...

The Proposed Action would meet demand for coal and sustain mine operations through at least 2024 by: Continuing to mine (84,000 tons of coal per year), process, and ship (via truck and barge) coal to customers in need of coal. Under the No Action Alternative, no mining activities would take place and reclamation activities
Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines
