Evaluation of load losses in the ventilation circuit by the use of fortification in coal mines, study case: Nechí Mine, Amagá, Antioquia
The research aims to identify the variables which influence on the increase of risk for explosions in underground coal mines, especially in the accumulation of coal dust on top of the fortification, as well as analyze how these affect the load losses in the ventilation circuit and the proper evacuat...
