    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
