Pike river mine disaster: systems-engineering and organisational contributions... Poor systems-engineering contributed via poorly designed ventilation, use of power-electronics underground, and placement of the main ventilation fan underground....
Comparison study of "u+l " and "y+l " working face ventilation patterns on gas control in a highly gassy mine... Furthermore, the main ventilation factors that affect the gas drainage of U+L ventilation pattern are optimized through the orthogonal test and fuzzy evaluation method; it effectively reduces ...
Justification of rational methods for provision of air to faces of operating coal mines of vietnam during deepening of mining... Re-lations have been obtained that determine the relationship between the aerodynamic resistance of negative regulators, the number of simultaneously developed working and development faces, the performance of main ventilation fans and the consumed electric power
Reversal of underground mine ventilationReversal of main ventilation is one of the important means to isolate a fire during emergency....
