Abstract
This report presents the results of the economic analyses of several applicable alternatives to increase airflow in four underground coal mines. Pressure and quantity surveys were conducted underground, and measurements were made at the main mine fans. The existing ventilation networks were modeled using a modified ventilation simulator, and the applicable alternatives were simulated. Performance data obtained from the simulation runs were utilized to conduct the cost-effectiveness analyses. The costs for each of the alternatives included capital, operating, and maintenance. These costs were expressed as annual ventilation costs per active section in terms of dollars per cubic foot per minute, taking into account the economic life associated with each of the alternatives. The benefits were expressed as increased airflow quantity in the critical sections. A section of the report also deals with comparison of simulator-predicted air quantity values against air quantity values measured underground.
