Monitoring and Remote Control. Environmental Monitoring. This mostly entails monitoring gases, dust levels, ventilation flow or pressure and in some cases temperature where heat at the working places can become a problem.
Also, separate ventilation shafts and roads can be used to improve ventilation networks, e. g. Kirunavaara Mine, Sweden (8). Roads used for ventilation only are usually designed with smooth walls and do not hold any mining equipment in order to keep the overall resistance low. The trend to deeper and more complex mines is still ongoing.
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 Mining Ventilation Laboratory is equipped with instruments to determine absolute (barometer) and relative (manometer) air pressure, wet and dry bulb temperature, quantitative testing for a variety of mine gases and contaminants, and a variety of anemometers.
Aug 17, 2018· Under MSHA regulations for atmospheric monitoring systems, monitoring in active mining areas usually involves methane and products of combustion around electrical and belt of ventilation airflow velocity is less common, with little information gathered on airflow direction. Large portions of many underground operations may not be continuously monitored .

An international review of regulations for dieselpowered equipment in underground mines, in Proceedings of 2 nd International Mine Ventilation Congress, Reno, Nevada, USA, .
"The mine ventilation system must be designed to provide and distribute sufficient airflow to areas of the mine where diesel equipment is being used. Typical ventilation rates in metal and nonmetal mines range from 75 to 200 cfm per brake horsepower in use. In coal mines the name plate airflow has been used to determine plan airflow requirements."
Atkinson resistance is commonly used in mine ventilation to characterise the resistance to airflow of a duct of irregular size and shape, such as a mine roadway. It has the symbol and is used in the square law for pressure drop, = where (in English units) . is pressure drop (pounds per square foot), is the air density in the duct (pounds per cubic foot),; is the standard air density ( ...
In this topic we will look at the various issues that arise with regards with people working underground and the principles behind mine ventilation systems. Ventilation is the control of air movement: its amount, its quality and its direction, to maintain a safe and healthy environment in which miners can work.
