A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although accidents also occur in hard rock mining. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries where safety measures are not practiced as fully. A mining disaster is an incident where there are five or more fatalities.
A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane. In industrial explosions many other gases, like hydrogen, as well as evaporated (gaseous) gasoline or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition, or use of alternative energy.

There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.
On 7 February 2008, fourteen people were killed and thirty six injured during a dust explosion at an Imperial Sugar owned refinery in Port Wentworth, Georgia, United States. Dust explosions had been an issue of concern among U.S. authorities since three fatal accidents in 2003, with efforts made to improve safety and reduce the risk of reoccurrence.
The 2010 Connecticut power plant explosion occurred at the Kleen Energy Systems power station in Middletown, Connecticut, United States at 11:17 am EST on February 7, 2010. The plant had been under construction from September 2007, and was scheduled to start supplying energy in June 2010. The initial blast killed five and injured at least fifty; one of the injured later died in hospital, bringing the total death toll to six.
The Upper Big Branch Mine disaster occurred on April 5, 2010 roughly 1,000 feet (300 m) underground in Raleigh County, West Virginia at Massey Energy's Upper Big Branch coal mine located in Montcoal. Twenty-nine out of thirty-one miners at the site were killed. The coal dust explosion occurred at 3:27 pm. The accident was the worst in the United States since 1970, when 38 miners were killed at Finley Coal Company's No. 15 and 16 mines in Hyden, Kentucky. A state funded independent investigation later found Massey Energy directly responsible for the blast.
On April 17, 2013, an ammonium nitrate explosion occurred at the West Fertilizer Company storage and distribution facility in West, Texas, United States, while emergency services personnel were responding to a fire at the facility. Fifteen people were killed, more than 160 were injured, and more than 150 buildings were damaged or destroyed. Investigators confirmed that ammonium nitrate was the material that exploded. On May 11, 2016, the Bureau of Alcohol, Tobacco, Firearms and Explosives stated that the fire had been deliberately set. That finding has been disputed.
The 2010 Tesoro Anacortes Refinery disaster was an industrial accident that occurred at the Tesoro Anacortes Refinery in Anacortes, Washington on April 2, 2010. Seven workers received fatal burns in an explosion and ensuing fire when a heat exchanger violently ruptured after a maintenance restart.
The 1995 Daegu gas explosions occurred at the Daegu Metro Line 1 construction site in Sangin-dong, Daegu, South Korea, on April 28, 1995. The explosion resulted in the death of at least 101 people, including 42 Yeongnam Middle School students, with as many as 202 people injured.
The 1944 explosion in Aarhus or the 4th of July Disaster was an explosion in the city of Aarhus, Denmark when a barge loaded with ammunition exploded in the harbor, killing 39 people and injuring another 250.
The Tangerang fireworks disaster occurred on 26 October 2017 at the PT. Panca Buana Cahaya Sukses, a fireworks manufacturing factory in Kosambi, Tangerang, Indonesia. The explosion occurred in a warehouse connected to the factory and ignited a large fire. 103 people were working at the factory at the time of the explosion. At least 49 people were killed and 46 others were injured in the fireworks accident. Authorities confirmed that several people were still missing. It was the deadliest industrial accident in Indonesia.
On 7 January 2008, a fire occurred in Icheon, South Korea, killing 40 workers as they were injecting urethane foam into the walls of the 20,000 square-meter basement. It happened at a cool warehouse that was under construction at a refrigerated goods facility. More than 500 firefighters fought the fire from which witnesses claimed to hear multiple explosions. Along with thick black smoke, toxic fumes hampered interior-attack firefighting operations. Holes were subsequently drilled in the roof to allow the toxins and smoke to escape.
