    The Constitution of Matte

    By Ruddle R. W.

    Solid mattes are generally held to be either (a) eutectiferous mixtures of the component sulphides Cu2S and FeS or (b) mixtures of complex sulphides. This chapter shows that liquid mattes consist esse

    Reliability and availability analysis of mining systems

    By Tuncel M. Yegulalp, Selamet G. Ergelebi

    A description is given of a method of analysing modern mining systems in terms of reliability and their effects on productivity. Non-exponential distributions, such as the Weibull and lognormal distri

    Study of bucket trajectory in automatic scooping with load-haul-dump loaders

    By A. Hemami

    In order to automate the operation of mechanical loaders it is essential to have a knowledge of the forces that act on the bucket and of the trajectory that the bucket should follow. A trajectory for
