The Role Of The Analogue Computer In Mine Ventilation

The capabilities of the analog computer, the Mine Ventilation Simulator, installed at WHA's Safety and Health Technology Center in Denver, Colorado, are discussed. General opera- ting procedures are described showing how a mine model is produced, and how the model can subsequently be modified to produce a solution to a mine ventilation problem. A sample problem is included to illustrate the technique. The important role the Mine Ventilation Simulator plays in ventilation training is discussed, including experiences with the education of students at the Colorado School of Mines. This paper includes a summary of some of the advantages and disadvantages of the analog technique and suggests some design criteria for application to future development of analog computers, based on experience gained with the Mine Ventilation Simulator.
