GAG units have been used in Australia, most notably in 2000 at the Blair Athol Mine, Queensland, where one extinguished a 54-year-old coal fire. [7] In 2003, a team from the Queensland Mine Rescue Service took a unit to West Virginia, where they successfully extinguished a 660-foot (200 m) deep, two-month-old fire at Loveridge Mine, after ten days of continuous use.
Even pouring or spraying acetone over red-glowing coal will not ignite it, due to the high vapour concentration and the cooling effect of evaporation. [79] Acetone should be stored away from strong oxidizers, such as concentrated nitric and sulfuric acid mixtures. [81] It may also explode when mixed with chloroform in the presence of a base.
In underground mining, long tunnels require efficient ventilation systems to protect miners' health and safety. Ventilation shafts are critical in these setups, as they introduce fresh air into deeper sections and expel contaminated air. These shafts are typically placed at regular intervals along the tunnel to ensure that airflow reaches all ...
Accidents involving the improper use of equipment and collapsing mines were frequent occurrences. Coal-mining was also one of the many dangerous jobs that employed child workers.
For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. [1] The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverized coal is a significant dust explosion hazard, as large quantities are suspended in air ...
Mine safety is a broad term referring to the practice of controlling and managing a wide range of hazards associated with the life cycle of mining-related activities.Mine safety practice involves the implementation of recognised hazard controls and/or reduction of risks associated with mining activities to legally, socially and morally acceptable levels.
Personal protective equipment lessens this risk, but maintaining adequate protection is not easy, especially as advancing mining technologies have made mechanized fracturing of the rock and coal more efficient on a per-worker basis, making more dust to control in tighter spaces and time frames.
A disused Huber coal breaker in Ashley, Pennsylvania, September 2003. The Huber Breaker was a coal breaker and landmark located in the borough of Ashley, Luzerne County, Pennsylvania. [1] The breaker was built in 1939 to replace the Maxwell Breaker after sustaining damage during a strike in 1937. Run-of-mine coal arriving at the breaker was ...
