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.
Alarm fatigue or alert fatigue describes how busy workers (in the case of health care, clinicians) become desensitized to safety alerts, and as a result ignore or fail to respond appropriately to such warnings. [1] Alarm fatigue occurs in many fields, including construction [2] and mining [3] (where vehicle back-up alarms sound so frequently ...
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]
In active mining operations, the threat from blackdamp is addressed with proper mineshaft ventilation as well as various detection methods, typically using miners' safety lamps or hand-held electronic gas detectors. The safety lamp is merely a specially designed lantern with a flame that is designed to automatically extinguish itself when ...
The mine ventilation fan, before 1908. Underground mine ventilation provides a flow of air to the underground workers of a mine with sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature. The source of these gases are equipment that runs on diesel engines, blasting ...
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 ...
Creep (deformation) In materials science, creep (sometimes called cold flow) is the tendency of a solid material to undergo slow deformation while subject to persistent mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material.
The fatigue limit or endurance limit is the stress level below which an infinite number of loading cycles can be applied to a material without causing fatigue failure. [1] Some metals such as ferrous alloys and titanium alloys have a distinct limit, [2] whereas others such as aluminium and copper do not and will eventually fail even from small ...
