Assessment of Mine Ventilation System Reliability Using Random
A mine ventilation system provides a fresh air flow to the underground workings in a coal mine. Such sufficient air volume can dilute and remove noxious gases (typically NOx, SO2, CH4, CO2 and CO) and maintain a suitable working environment for coal miners. On the other hand, a poor ventilation system often leads to serious consequences such as …
Auxiliary ventilation systems in mining and tunnelling
Ventilation systems are required during the construction of tunnels and mining roadways to provide a safe environment for workers and dilute the blasting fumes and combustion gases from diesel equipment (Parra et al., 2006).In addition, according to the international regulations, a minimal air speed in the underground infrastructure must …

Assessing Emissions from Active and Abandoned Coal Mines
In most active mines, coal mine methane is controlled by wellbores, called gob gas ventholes. Despite the presence of these wellbores, it is not possible to capture all of the methane generated within the gas emission zone. As a consequence, a large amount of gas migrates into the mine and is exhausted to the atmosphere with ventilation air.

Coal
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...
