Mine-Ventilation Digital Simulation and Analysis Capabilities at MESA'S Denver Technical Support Center

摘要

In the study of the ventilation system at any given mine, it is common to collect data on airflow quantities and pressures at key points throughout the mine. Only when these data are compiled and assembled into usable form can the engineer begin to understand the system as a whole. These data give only a point-in-time view of the system. As the mine develops and progresses, the system undergoes numerous changes. As the mine becomes more extensive, the ventilation requirements increase and costs rise. It is necessary for the engineer to have a sound engineering basis for his decisions on how best to ventilate the mine if he is to use his resources to the utmost. In order to evaluate the system as a whole, particularly with regard to possible changes to be made to the system, it has become necessary to rely on computers to do the calculations involved in analyzing the network. This report summarizes the implementation of such computer capability and the services available at the Denver Technical Support Center. Listings of the programs used in the modeling of ventilation networks and documentation for use of the programs are provided. Usage of data and ventilation simulation as a service by Denver Technical Support Center is explained. (ERA citation 08:045392)
