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.

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.61.0 m (2 ft 0 in3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 34 km (1.92.5 mi) long and 250400 m (8201,310 ft) wide.

15/5/2015· Thereafter, the fan speed optimization problem is solved to determine the optimal fan speed profile throughout the mining processes that matches the VOD and reduces energy consumption. For the fan speed optimization problem, the fans operating point is correctly determined by incorporating the fan laws and the networks system curve to get a realistic figure of the savings [18] , [35] .
