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.

The Cross Mountain Mine disaster was a coal mine explosion that occurred on December 9, 1911, near the community of Briceville, Tennessee, in the southeastern United States. In spite of a well-organized rescue effort led by the newly created Bureau of Mines, 84 miners died in the disaster.

On 10 December 1910, an explosion occurred underground in the West Canadian Collieries No. 1 Mine in the Crowsnest Pass community of Bellevue, Alberta. The explosion pushed all of the air out of the mine and filled it with afterdamp, a deadly gas that is a mixture of Carbon dioxide and Carbon monoxide, killing 30 of the 42 workers present at the time, as well as one rescue worker. The explosion was the first mining disaster in Alberta's history, and led to several changes in coal mining in the Crowsnest Pass. The event was soon overshadowed by the nearby Hillcrest mine disaster four years later, which killed 189 and is Canada's worst mining disaster to date.
