Classification of underground mining methods
By P. A. Rossouw, G. A. Fourie
Several attempts have been made over the latter half of the twentieth century to devise a system for the classification of underground mining methods. None of these are found to be totally successful.

Avoiding the zero-flow solution in mass-balance equations
By S. L. Gay
The conventional mass-balance equations used as constraints can lead to flow estimate values of zero even though the flow estimates should be some positive number. This is because many of the constrai

Estimation of mechanical rock properties using wireline geophysical measurements
By L. Wade, R. Wang, M. A. Horton
Laboratory methods to find the mechanical properties of rock are inherently biased towards stronger strata, which best survive the sample preparation process. Geophysical techniques are not subject to
