Historically, coal mining has been a very dangerous activity, and the list of historical coal mining disasters is long. The principal hazards are mine wall failures and vehicle collisions; underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions.
Machinery trying to mine the coal may not be able to reach the displaced seam, if the displacement is too large. Coal mines use a combination of boreholes and high-resolution seismic reflection data to identify the larger faults and avoid the most faulted areas at the mine planning stage. [1]
Coal mining accidents resulted in 5,938 immediate deaths in 2005, and 4746 immediate deaths in 2006 in China alone according to the World Wildlife Fund. [10] Coal mining is the most dangerous occupation in China, the death rate for every 100 tons of coal mined is 100 times that of the death rate in the US and 30 times that achieved in South Africa.
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).
Coal mining has been a very dangerous activity and the list of historical coal mining disasters is long. In the U.S., 104,895 coal miners were killed in mine accidents since 1900, [32] 90 percent of the fatalities occurring in the first half of the 20th century. 3,242 died in 1907, the worst year ever; in 2020 there were five.

Some mining methods (lithium mining, phosphate mining, coal mining, mountaintop removal mining, and sand mining) may have such significant environmental and public health effects that mining companies in some countries are required to follow strict environmental and rehabilitation codes to ensure that the mined area returns to its original ...
As mining progresses, this pressure can be violently released, resulting in an outburst. The statistical results show that the primary factor in coal and gas outbursts is crustal stress (P), followed by sturdiness coefficient (f). The coal seam gas content (W) affect affects coal and gas outbursts as the least important factor. [2]
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.
