Gas explosion, which is the main type of accidents reported in coal mines, comes with serious economic and safety consequences. The present work adopts the "glass heart" model for assessing the vulnerability of coal mines to gas explosions based on a constructed gas explosion vulnerability assessment index system. The proposed index system is applied to a coal mine in Henan Province, China ...
Floating coal dust fueled it, and when it finally blew, the resulting blast was fed by coal dust spread throughout the mine, which explains an explosion that turned corners and killed along a 2 ...

Coal is an important fossil fuel energy that occupies a high position in the energy use of China and even the world. However, gas explosions are still the deadliest coal mine accident in China, which has long plagued the safety of energy mining. Only through accident cause analysis can we know the exact cause of the accident so as to make targeted policies, safety trainings, etc. However, the ...
This paper critically analyzes data on major explosions that have occurred at Indian coal mines over the past 120 years (). An estimated % of mine explosions and % of associated ...
There are two main types of coalmine explosions: methane and coal dust. Methane explosions occur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below its explosion point. Likewise, fine particles of coal dust in the right concentration that contact a source of heat can also be explosive.
The Battle of Blair Mountain was the largest labor uprising in United States history and is the largest armed uprising since the American Civil War. The conflict occurred in Logan County, West Virginia, as part of the Coal Wars, a series of early20thcentury labor disputes in Appalachia.. For five days from late August to early September 1921, some 10,000 armed coal miners confronted 3,000 ...

Coal seams also contain explosive methane gas and coal dust, an accelerant that feeds explosions. So the world's coal mines, which supply 30 percent of global energy needs, are volatile places.
and control of coalmine gas explosion risks [10,11]. Therefore, it is of great significance to find new effective ways to help in coalmine gas prevention and control. To establish the circumstances of coalmine gas explosion accidents and improve safety management in coal mines, the statistical analysis of accidents is necessary, and common.
mines is to suppress methane explosions, prevent methane explosions escalating into coal dust explosions and to suppress coal dust explosions and prevent the explosions from propagating. The use of active explosionsuppression systems remains one of the most underutilised explosion controls in underground coal mines (du Plessis and Spa¨th 2014).
Miners used a machine called a scoop to gather the loose coal and dump it on a conveyor system. ... seven miners were killed in a massive coaldust explosion at the RFH Coal Co. No. 1 mine in ...

This is an incomplete list of notable mining accidents and disasters: 19th century May 25, 1812: Felling Colliery Disaster explosion killed 92 men and boys. July 15, 1856: Cymmer Colliery explosion in Cymmer, Rhondda Cynon Taf, Wales. 114 men and boys killed. [7]
In August, another coal mine explosion also killed 11 people in northern China's Shaanxi province. A coal mine fire in southern China's Guizhou province killed 16 people in September. Just a few weeks ago, a major fire at a coal mining company building in northern China killed 26 and injured dozens, though the blaze was not in the mine itself.
