Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
The Occupational Safety and Health Act of 1970 is a US labor law governing the federal law of occupational health and safety in the private sector and federal government in the United States. It was enacted by Congress in 1970 and was signed by President Richard Nixon on December 29, 1970. Its main goal is to ensure that employers provide employees with an environment free from recognized hazards, such as exposure to toxic chemicals, excessive noise levels, mechanical dangers, heat or cold stress, or unsanitary conditions. The Act created the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH).
Mining in the engineering discipline is the extraction of minerals from the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
For most of the 20th century, the United States Bureau of Mines (USBM) was the primary United States government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources. The Bureau was abolished in 1996.
The Mine Safety and Health Administration (MSHA) is a large agency of the United States Department of Labor which administers the provisions of the Federal Mine Safety and Health Act of 1977 to enforce compliance with mandatory safety and health standards as a means to eliminate fatal accidents, to reduce the frequency and severity of nonfatal accidents, to minimize health hazards, and to promote improved safety and health conditions in the nation's mines. MSHA carries out the mandates of the Mine Act at all mining and mineral processing operations in the United States, regardless of size, number of employees, commodity mined, or method of extraction. David Zatezalo was sworn in as Assistant Secretary of Labor for Mine Safety and Health, and head of MSHA, on November 30, 2017. He served until January 20, 2021. Jeannette Galanais served as Acting Assistant Secretary by President Joe Biden on February 1, 2021 until Christopher Williamson took office on April 11, 2022.
Mining law is the branch of law relating to the legal requirements affecting minerals and mining. Mining law covers several basic topics, including the ownership of the mineral resource and who can work them. Mining is also affected by various regulations regarding the health and safety of miners, as well as the environmental impact of mining.
The Surface Mining Control and Reclamation Act of 1977 (SMCRA) is the primary federal law that regulates the environmental effects of coal mining in the United States.
The Federal Coal Mine Health and Safety Act of 1969, U.S. Public Law 91-173, generally referred to as the Coal Act, was passed by the 91st United States Congressional session and enacted into law by the 37th President of the United States Richard Nixon on December 30, 1969.
The Sago Mine disaster was a coal mine explosion on January 2, 2006, at the Sago Mine in Sago, West Virginia, United States, near the Upshur County seat of Buckhannon. The blast and collapse trapped 13 miners for nearly two days; only one survived. It was the worst mining disaster in the United States since the Jim Walter Resources Mine disaster in Alabama on September 23, 2001, and the worst disaster in West Virginia since the 1968 Farmington Mine disaster. It was exceeded four years later by the Upper Big Branch Mine disaster, also a coal mine explosion in West Virginia, which killed 29 miners in April 2010.
The Safety and Health in Mines Convention, 1995 is an International Labor Organization Convention adopted at the 82nd International Labor Conference (ILC). The convention (C176) was developed and adopted to better recognize the inherent hazards of the mining workplace and the necessity of addressing these hazards on a global scale.
The United States National Mine Health and Safety Academy is a federal academy responsible for training the mine safety and health inspectors and technical support personnel of the Mine Safety and Health Administration.
The Mining Enforcement and Safety Administration (MESA) under the U.S. Department of the Interior was the predecessor of the Mine Safety and Health Administration, prior to March 9, 1978. It was formed by the Federal Coal Mine Health and Safety Act of 1969, and co-approved respirators with NIOSH under 30 CFR Part 11. It was dissolved and replaced with MSHA following the passage of the Federal Mine Safety and Health Act of 1977.
The Ministry of Mines is the ministry in the Government of India. The ministry functions as the primary body for the formulation and administration of laws relating to mines in India. The head of the ministry is G. Kishan Reddy, who has been serving since June 2024.
Mining in the United States has been active since the beginning of colonial times, but became a major industry in the 19th century with a number of new mineral discoveries causing a series of mining rushes. In 2015, the value of coal, metals, and industrial minerals mined in the United States was US$109.6 billion. 158,000 workers were directly employed by the mining industry.
A mine rescue chamber is an emergency shelter installed in hazardous environments, typically underground. It is also known as refuge chamber, refuge bay, or refuge alternative. Refuge chambers come in multiple types and models, and are used in multiple industries including metalliferous mining, coal, tunnelling and petrochemical facilities.
The United Kingdom Mines and quarries regulation in 1910 was a specialised topic in UK labour law, given the complexity of the legislation and seriousness of injuries that people suffered.
The Federal Coal Mine Safety Act of 1952 is a U.S. law authorizing the federal government to conduct annual inspections of underground coal mines with more than 15 workers, and gave the United States Bureau of Mines the authority to shut down a mine in cases of "imminent danger." The Act authorized the assessment of civil penalties against mine operators for failing to comply with an order to shut down or for refusing to give inspectors access to mine property. The law did not authorize monetary penalties for noncompliance with the safety provisions. In 1966, Congress extended coverage to all underground coal mines.
Federal Mines Safety Act of 1910 was a United States statute passed for the purposes of establishing the United States Bureau of Mines as a federal agency of the United States Department of the Interior. The Act of Congress authorized investigations of mining methods with an emphasis regarding the safety of miners while recovering combustible fossil fuels and confronting occupational dust exposure.
The Scotia Mine was a coal mine that operated in the community of Oven Fork in Letcher County, Kentucky. The mine began operations in 1962, as a subsidiary of the Blue Diamond Coal Company. In March 1976, two explosions occurred within the mine, killing 26 miners. The explosions led to the passage of several acts relating to safety in coal mines.
