Rational shape of metal support for development workings
Authors:
Abstract
The stability of mine workings depends to a large extent on the shape of their cross-section and the corresponding outline of the support. However, this well-known principle is often not taken into account, as a result of which the load-bearing capacity of the support is not fully utilized.
