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 ...
A coal fire in China Open-cast mining continues near a fire at Jharia coalfield in India. A coal-seam fire is a burning of an outcrop or underground coal seam. Most coal-seam fires exhibit smouldering combustion, [1] particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth ...
Historically, coal mining has been the most dangerous energy activity and the list of historical coal mining disasters is a long one. Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions. Open cut mining hazards are principally mine wall failures and vehicle collisions.
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 ...
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.
