Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an exhausted mining site during reclamation. [1] Interburden is material that lies between two areas of economic interest, such as the material separating coal seams within strata. [2] [3]
Fatigue detection software is intended to reduce fatigue related fatalities and incidents. Several companies are working on a technology for use in industries such as mining, road- and rail haulage and aviation. The technology may soon find wider applications in industries such as health care and education. [citation needed]
The Mine Safety and Health Administration (MSHA) (/ ˈ ɛ m ʃ ə /) 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 (Mine Act) 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 ...
Increases in worldwide demand for resources have resulted in Australia's annual mining production has more than doubling in the 20 years up to 2008. [2] There are approximately 365 operating mines in Australia, and as for the employment of up to 269,000 people, the mining and resource industry contributes 121.5 billion dollars to the economy.
Specifically in sedimentology, a bed can be defined in one of two major ways. [2] First, Campbell [3] and Reineck and Singh [4] use the term bed to refer to a thickness-independent layer comprising a coherent layer of sedimentary rock, sediment, or pyroclastic material bounded above and below by surfaces known as bedding planes.
A Soviet-designed drill used a motor to provide vertical vibration to the barrel of the drill at 50 Hz; the drill had an outer diameter of 0.4 m, and in tests at Vostok Station in the Antarctic drilled a 6.5 m hole, with a 1.2 m drilling run taking between 1 and 5 minutes to complete. The drill's steel edges compacted snow into the core, which ...
Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved.

Alarm fatigue occurs in many fields, including construction [2] and mining [3] (where vehicle back-up alarms sound so frequently that they often become senseless background noise), healthcare [4] (where electronic monitors tracking clinical information such as vital signs and blood glucose sound alarms so frequently, and often for such minor ...
