SIMULATION OF QUANTITY AND QUALITY CONTROL IN MINE VENTILATION

Special Research Report SR-95 The provisions of The Federal Coal Mine Health and Safety Act of 1969 has placed greater emphasis on mine ventilation systems. Besides, larger, complex mines with more difficult natural conditions require a greater quantity of air and more efficient distribution. It has long since become evident that better planning and more efficient projections, resulting from greater mechanization and sophistication of mining systems and increased production, are necessary to improve mine ventilation systems. This objective can be achieved by utilizing ventilation science and art and by the application of digital computers in the solution of ventilation problems. The real power of the computer, however, lies in the planning of ventilation systems and in the solution of complex ventilation networks with multiple intakes and fans where manual calcula- tions are impractical. This research report has, therefore, introduced to the mine operators yet another application of computers as a planning tool,
