One of the world's worst coal mining accidents took place at the Benxihu Colliery in Benxi, China. In April 1962, a fire broke out after gas and coal dust exploded.
Coal mining deep underground involves a higher safety risk than coal mined in opencast pits, due primarily to problems associated with mine ventilation and the potential for mine collapse. However, there are safety risks associated with all forms of coal mining, not least because of the heavy machinery utilised in coal excavation.
Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.
The environmental toll of underground mining is significant. It includes air pollution, changes in water-flow patterns, chemical and gas seepage into water supplies and soil, inaccessible fires in abandoned mines, and dramatic changes in land composition that can make the area unusable after the mining operation is done [source: Saxena]. Then there is the human toll.
Respirable quartz hazard associated with coal mine roof bolter dust G.J. Joy, T.W. Beck & J. M. Listak National Institute for Occupational Safety and Health (NIOSH), Pittsburgh, PA, USA ABSTRACT: This study examined the potential for coal mine roof bolter dust to be a source of a worker's exposure to respirable quartz.
Rock dusting to prevent coal dust explosions has been in widespread use in U.S. underground coal mines since the early 1900s. Underground coal mining technology has changed significantly over this same time period, becoming highly mechanized and produces finer coal .
