It is suggested that if adequate knowledge is available about classifiers in closed grinding circuits, these units may be used as on-stream size analysers when equipped with suitable sensing devices. Research work which is at present in progress to enable a hydrocyclone to be used for this purpose is discussed.

Most mining dredges are adapted from canal/harbour dredges. Their automation and control systems are generally not designed for integrated mining operations. Consequently they have a number of limitations. This paper describes a new dredge control concept which paves the way for improved efficiency and increased production.

The direction taken by mineral processing in the next 20 years will be determined by sharing of Australia's resources to fill world needs; by the low energy costs in Australia; by environmental considerations; and by Re- search and Development contributions. Examples of the interplay of these factors are given by consideration of eight minerals.

1 eat my peas with honey I've done it all my lifeIt makes them taste rather funny But it keeps them on the knife.Innovation is that elusive characteristic which involves the determination of multiple and unique response to a problem, and then commitment to and action from the best of the alternatives.

In this paper, impact of expert systems development is examined from the coal mining point of view. Some introductory concepts about expert systems are explained with a view to identifying possible beneficial applications of expert systems in coal Mining.

This paper mainly studies the creation and optimisation of a doublesymbol random engineering network, by means of developing a set of engineering network project dynamic decisions and an optimisation sustaining system, which can realise engineering network dynamic workout and optimisation. It can provide a good decision for engineers and managers to supervise and manage the construction development and to ensure completion of the construction on time.

As the awareness and concerns on subsidence issues increase, there are clear, challenging and credible community expectations for responsible mining, public safety, optimal resource recovery and effective land use and environmental management, coinciding with a changing and strengthening regulatory environment being implemented by the NSW Government. This paper discusses a number of areas where cultural changes in the mining industry will assist with improved subsidence management to meet the enhanced standard.

Management of risk has always been an integral part of successfully executing engineering and construction projects although formal recognition of the discipline of risk management is a relatively recent development. This paper describes the establishment and application of a proprietary business risk management framework for FluorÆs global engineering and construction business.

This paper presents the descriptions of a final year geological engineering project at the Royal Melbourne Institute of Technology involving the correlation of borehole and mapped ground conditions and their statistical Analysis.

A schematic overview of the variables which interact to determine ore reserves precedes consideration, in this context, of some recent views on the concept of a 'production cycle'. Political and governmental action, for whatever motives, is a greater obstacle to future mineral supply than technical problems.

Difficulties with froth flotation recovery and vacuum de- watering equipment for the treatment of fine coal have been investigated. Mechanical alterations to cyclone desliming banks, and flotation cells are described. A large disc filter has been replaced by two drum filters for dewatering, and the improvement in plant. operation is discussed:

Concentration ranges are presented for 15 trace elements not previously reported in Australian bituminous coals. The results were obtained by instrumental neutron activation analysis, which has sufficiently high sensitivity to enable determination of many elements directly in coal at concentrations less than a few µg/g. The ranges found in Australian coal are similar to the ranges reported in North American bituminous coals.

The paper presents an algorithm for calculating the natural air distribution in a ventilation network (sub-network) on the basis of following data: - for each network branch: labels of starting and ending nodes, label of the branch, resistance and natural depression; - for each fan: the characteristic in the form of a second order equation and initial flow.

Thank you for that introduction and especially thank you to the organisers for inviting me. I've had a considerable interest in this area and I've had the advantage of an education from Neil on the subject of offering documents as a result of our collaboration together on the Securities Information Review Committee.

I.T.H. Drilling has been accepted as a tool used daily for both production and service work in Australian underground mines. For this reason, it is of interest to examine the rigs and drilling equipment in use to do this work, also to review the technique necessary to ensure that this drilling is done efficiently.

The needs for improved technology for the mineral industry are widely recognised and a summary list is given. Ways in which technology has been introduced into the industry are discussed, as are the means by which the general process of technology transfer takes place. Some possible sources of improved and new technology are considered, together with the constraints to its introduction into the industry. Responses to recent external influences on the industry are discussed in relation to their effects on technology development.

Hoesch HUttenwerke AG, Dortmund, West Germany, is an integrated steel work of the Estel-group. The nominal annual production capacity-is about 7 Mio tons of steel. Hoesch has along experience in operation of diffe-rent types of slag granulation plants and of utilization of the granulated product. This experience is used to granulate a large amount of blast furnace slag and to process it in own cement plants and produce blast fur-nace cement.

A mathematical model is set up to solve the problem of optimal design of the production scheduling on exacting open pit mine. At the same time, the establishment of model in operation condition and its solution are considered completely. It gives not only algorithm of optimal design but also strict mathematical argumentation in the process of optimal design.
