The Future Of The Analog Technique For The Simulation Of Mine Ventilation Networks ? Introduction

Consequent on the development of digital computers the importance of analog simulation as a means of studying engineering problems has diminished in recent years. The general-purpose nature of a digital computer ensures its applicability to a wide range of tasks whereas an analog simulator is confined to the one specific use for which it was designed. Nevertheless the analog technique remains attractive in its application to certain aspects of the study of mine ventilation networks, for reasons which will now be developed.
