In addition, there have been many coal mining disasters, although work related coal deaths has declined substantially as safety measures have been enacted and underground mining has given up market share to surface mining. [citation needed] Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions.
This week's coal mine disaster in West Virginia brings with it grim but familiar images and headlines, a new chapter in American coal mining's sometimes tragic legacy. The accident also reminds us ...
Mining accidents can occur from a variety of causes, including leaks of poisonous gases such as hydrogen sulfide [2] or explosive natural gases, especially firedamp or methane, [3] dust explosions, collapsing of mine stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment).
Gases underground present hazards of asphyxiation and ignition, depending on which gases are present in each part of the mine. Mine ventilation is one of the many capital costs of extending the mine. Mines without good safety culture were often lethal to the workers in centuries past, and although the per capita rates of injuries and deaths are ...
On the morning of Aug. 4, 1917, a methane gas explosion at the Western Kentucky Coal Company’s No. 7 mine in Webster County killed 62 of the 153 men underground at the time. The other 91 men in ...
Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal, bucket wheel excavators, and ...
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.
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.
