01/07/2019 · Fig. 15 shows the ventilation performance of working coal face section with brattice and ducted fan in terms of the air velocity patterns for two different distances of duct from the working coal face h = 8 m (Fig. 15(a)) and h = 5 m (Fig. 15(b)). The intake air velocity is assumed to be constant (2 m/s) and the brattice length and its distance from the wall are BL = 11 m and x = 0.6 m ...

Ventilation System Design for a Thin-Seam Mining Panel

Ventilation in a thin-seam coal mine follows the same rules and principles as ventilation in thick seam coal mining. The main difference is the design of the method to extract the coal. In tlris case we are suggesting an automated coal winning system that can be run and maintained by miners in tlle development sections. The mining height in these mines will be in the area of 30 inches, and the ...
