A Computer-Controlled Electrical Resistance Network Analog for Rational Mine Design.

摘要

The report describes a combined analog-digital computer system for solving problems that are impractical when either device is used separately. This method applies to the important class of mining problems involving excavations in tabular seam or vein-type deposits. The hybrid computer system has many implications for rational planning of underground excavations since it allows practically any type of inelastic seam behavior or artificial support characteristics to be simulated. Inelastic seam behavior,for example,might be due to either rock failure or to time-dependent deformation. The hybrid computer shows considerable potential as a design tool for coal mine layout. It is ideally suited to investigations of effects of design changes due to the speed with which parameter changes can be implemented.
