The Monongah Mining Disaster was the worst mining accident of American history; 362 workers were killed in an underground explosion on December 6, 1907, in Monongah, West Virginia. The U.S. Bureau of Mines was created in 1910 to investigate accidents, advise industry, conduct production and safety research, and teach courses in accident ...
Peabody Energy developed two coal strip mines on the Black Mesa reservation: the Black Mesa Mine and the Kayenta Mine. The company pumped water from the underground Navajo Aquifer for washing coal, and, until 2005, in a slurry pipeline operation to transport extracted coal 273 mi (439 km) to the Mohave Generating Station in Laughlin, Nevada.

At the time of its discovery, the deposit of kyanite on the mountain was the world's largest [ 2 ] United States Environmental Protection Agency (EPA) testing has determined that approximately 450 residences in the vicinity relying on well water ...
Sustainable Mining Practices: As environmental concerns grow, companies are exploring more sustainable and eco-friendly mining practices for kyanite extraction. Product Development in High-Temperature Applications : Research and development in kyanite-based products are focusing on extending their lifespan and enhancing their resistance ...
Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock. It is the high pressure polymorph of andalusite and sillimanite , and the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in the Earth's crust .
