Mine Ventilation
|
| Underground mine ventilation theory and practice are provided, including basic concepts of airflow quantity, air pressure, and resistance to flow. The effect of density on quantity and pressure due to elevation and water vapor are detailed. Absolute and differential air pressures underground are explained, along with the equipment with which they are measured. How the mine ventilation network affects measurement positions, both in coal and metal/nonmetal mines, is shown. | 
|
Also demonstrated will be how a network is modeled based on the actual mine, then onto the mine map, and then onto a simplified ventilation schematic. A hands-on, actual mine ventilation quantity-pressure survey underground will be made at the Colorado School of Mines Experimental Mine (Edgar Mine) at Idaho Springs. The network airflow quantities are hand calculated and balanced, along with the pressures and resistances. The computer simulations are then shown for speed, simplicity, and accuracy and comparisons of the actual Edgar Mine data are used for the class. Both axial flow and centrifugal fan measurements and theory wind up the class.
The objective of the class is to give a basic working knowledge of underground mine ventilation so that each student can make a pressure-quantity survey of a mine, calculate, and balance it for engineering use by management.
