Underground mine ventilation - Wikipedia

The mine ventilation fan, before 1908. Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature. The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. The ...

Asbestosis - NHS

Asbestosis is a serious lung condition caused by long-term exposure to asbestos. Asbestos is a fibre-like material that was once used in buildings for insulation, flooring and roofing. Its use has been fully banned in the UK since 1999. While asbestos can be dangerous, it's not harmful if left alone. But if material containing asbestos is damaged, it can release a fine dust that contains ...
