Successful management is ultimately measured by return on shareholders' funds. This is the inescapable and inexorable discipline that ultimately rules every investment. Shareholders today are predominantly, and increasingly, the superannuation funds and insurance funds of almost all of us. We have already reached the situation in Australian investment history in which the best interests of employees can be very directly identified with the best interests of the owners of the capital invested.

The principles of occupational risk evaluation resulting from the improper ventilation of the underground mines were presented. It was shown that the risk level implies the appropriate planning and usage of prevention methods. That approach is fundamental in the ventilation, fire and climate safety management in the copper ore mines. The paper uses the adequately modified Risk Score method.

Prior to the 20th century much of our infrastructure was provided by the private sector. This included toll roads, tunnels and bridges, power supply, transport and water.With the depressions of the 1890s and 1930s and the world wars, much of this infrastructure passed into public ownership. This was certainly the case in Australia as well as many other Western countries.In the last quarter of the 20th century we are seeing a swing back to private sector provision of infrastructure,-resulting'from increased needs for investment in infrastructure due to changes in

The Paracale gold region had been known for hundreds of years, but the first professional attempts to work the lode and alluvial deposits were made only in the 1890s by the London-based Philippines Mineral Syndicate. Complex ores, transportation problems, and the Philippine Insurrection halted operations. Ultimate success went to American firms, though Frank Karuth's Philippines Mineral Syndicate had pioneered the field.

The Metallurgical processes used in the gold industry in Queensland since the 1850's are reviewed. The major upswing in, gold processing this decade has brought the technology of heap leaching, carbon in pulp and carbon in leach, flotation for gold and tailings retreatment to Queensland. In many cases operators have developed or improved these processes to treat difficult ores or to cope with local climatic conditions.

The motivation for, the structure of, and the overall features of a block release Graduate Diploma program designed for practising minerals engineers are outlined. It is demonstrated that because of the very specific subjects taught, the course has the potential to effect significant improvements in operating plant performance. Through lifting the skill level of the participants and therefore advancing their career prospects, the course can raise staff morale and improve plant performance and productivity in their work place.

The Centre for Mining Technology and Equipment was established in 1991 to develop innovative technologies for the mining and processing industries, to introduce these technologies to the industry, and where appropriate, to co-operate with equipment manufacturers to transform these technologies into equipment products. It is an unincorporated joint venture between the University of Queensland, CSIRO and the Australian Minerals Industries Research Association. Base funding for the CMTE is provided by the Federal Government as a Co-operative Research Centre.

The intention of this paper is to give a review of the present status of lignite mining in the so-called Gulf States in the United States of America, namely Texas, Arkansas, Mis- sissippi and Louisiana. The situation in these states is similar to the situation in Australia in that "Strip Mining - 45 m and Beyond" repre- sents the main technical problem to be over- come in the near future. The solution lies in the application of the bucket wheel excavator.

A variety of rockbolt designs and resin anchors are currently in use in underground mines. This paper identifies possible risk factors that may affect the intended performance of rockbolts. The paper also presents the outcome of a study on the variability of some aspects of fully encapsulated rockbolts undertaken across seven coal mines within the context of previous research findings on rockbolt anchorage performance.

The traditional form of project financing for resource related projects has involved project financings structured with either recourse to the project sponsor(s) or commercial banks accepting the project's risks, usually after project completion, subject to, inter alia, the nature of the project, geographical location, quality of the projected cash flows and commodity price outlook. However, the concept of commodity-linked borrowings hasadded a new dimension for borrowing opportunities for resource-oriented projects and or companies.

Aspects of sampling are becoming more complex, involving a correct statistical approach to collection as well as geological and possibly pedological control. Advanced chemical techniques and techniques of rapid analysis need to be understood. Results may require statistical analysis. The elementary aspects of sampling still need constant attention by those controlling a programme of sampling. No one person will have sufficient knowledge of statistics, geology, pedology and chemistry to be fully conversant with all the aspects of sampling but, by developing a correct approach, problems can be identified and solved.

Recent increase in the development of underground space in urban areas in Australia has included soft ground tunnel construction. The ground movements associated with soft ground tunnel construction may present risk to other existing and proposed structures in the nearby vicinity. Much experience has been gained both in the UK and Asia in recent years in the engineering evaluation of this risk. The paper presents a procedure to assess these aspects of soft ground tunnel construction with reference to recent projects.

When mining of ilmenite deposits wet process of preparation is traditionally used. But this method needs large volume of water. The problem of water deficiency is characteristic of many regions of the Republic of Kazakhstan. The Satpayevskoye ilmenite deposit is situated in the East Kazakhstan, its location has problems with water, and the mineralogical composition of rock is unfavourable: rocks contain up to 40 per cent of clays. That is why designers made a decision to use dry process of preparation for processing of these ores. Offered scheme and equipment selection are presented in this paper.

Thank you for the invitation to this forum today. I have a hectic schedule in the Mabo legislation process but it is important not to lose sight of the bigger picture and to attend today to talk to you about the Government's role in the development of our country.More importantly, I hope over the next couple of hours to get some feedback on developments in this area from people very much involved on a day to day basis.

Weinberg, born and educated in Germany, worked in'the American West for 10 years as a mining engineer and metallurgist. He was the first head of the Queensland Smelting Co. and from 1889 through 1915 was a prominent mining figure in Queensland. He was a competent manager at Aldershot, Dapto, and Chillagoe, but always lacked huge ore deposits for his smelters.

The author presents various procedures for the choice of dri-ving systems for mining, including the method of indeterminate Lagrange factors and linear programming.The possible application of the points-awarding method is demonstrated.It allows for taking into account both surd and commensurable characteristics of a driving system for mining. Also, the method of economic efficiency factors is outlined.All these methods make possible the best choice of a driving system, from the as-pect of electric energy saving. Two examples are given.

Every year my consultancy business reviews over 100 mines worldwide, primarily focusing on property and business interruption risk. What we have found is that the most successful mines have: identified their principal risks and determined what controls are required to manage or eliminate these risks; and managements systems that underpin these risks and the business in general.

Following plant trials in 1972 Mount Lyell installed an AMDEL On Stream Analysis system for measuring copper and density on the flot- ation feed and final plant tailing streams, in August 1973. As a result of poor performance of the final tailing system these probes were changed over to the rougher tailing stream, back to the final tailing stream and finally to the final copper concentrate stream where the system is currently performing satisfact- orily. The history of the development of the system to its current operational status is Described.
