Powered support plays a major role in longwall mining and improper selection may lead to a disaster. While different countries follow different norms, a universal approach is needed to be developed. For this purpose, a computer program C-ALPS

Three applications of fuzzy logic in mineral exploration show the possibility of providing feasible solution and allow greater freedom in decision-making processes for geoexploration data which may be ill- defined, biased or where apriori infor

It is a pleasure for me to be able to address you today. My Chairman, Sir Eric Neal will not be able to be here until later in the morning and he has asked me to deliver this speech on his behalf.

This paper attempts to put into perspective the implications of the legal disclosure requirements for promoters and consultants when making statements concerning ore resources and reserves. The need to take account of non-technical as well as technical factors is highlighted.

Thank you for asking me to address you. The topic may sound formidable. Those of you with determination to go somewhere in your careers will understand that by taking geoscience, mining and metallurgy courses as students, you are declaring your intere

In the paper a complex problem was formulated for studying and establishing an effective and safe technology of selective underground leaching of useful components from polymetallic ores. Solving this problem will allow increasing technical and economic efficiency, technological and ecological safety of mining of useful minerals of polymetallic deposits.

This paper presents the results of studying the influence of catastrophic failures arising in mines, on the behaviour of mine ventilation systems. It is very important to take account of this influence for the stable operation of the system and to ensure mine safety when mining underground coal and ore deposits.

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.

It is extraordinary that while Australia depends heavily on mineral wealth for its economic well-being, most Australians have no appreciation of the traditions and principles which drive and govern the mineral industry. Their understanding has been largely provided by those who campaign against the industry in one way or another and is therefore quite unrepresentative.

Lime is the common reagent used for pH control in cyanide gold circuits. Lime can be supplied as either quicklime (CaO) or 'hydrated lime(Ca(OH)2). Both are dry powders with variable flow properties. These properties demand special attention when designing machin- ery to handle them.

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.

The influences on flotabilities of dolomite and magnesite with modifiers and influences on the function of collectors and modifiers with Mg+z Ca+2 were studied. The flotation results of artificial mixed mineral showed that using combined salified water glass and (NaPO3)6 as a modifier for magnesite-dolomite separation can obtain an excellent Selectivity.

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.

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 results from three quick methods for the determination of W03 in scheelite ore samples, mill products and concentrates were compared with gravimetric results and tested with standard samples to establish which was the most reliable. Summaries of the methods, two X-Ray fluorescence and one colorimetric, are given. The best method was X-Ray fluorescence, with samples cast as glass discs.

A pilot pump rehabilitation programme commenced at Isa Mine in the late 1960ts. Over the years, it has now been developed into a full scale repair programme resulting in large operating cost savings. This paper will examine various materials used as wear media in the rehabilitation of pump parts for recycling, the use of other materials in manufactured design and appli- cations of these principles to other process Equipment.

Dealing with Aboriginals and various others purporting to represent them has become part and parcel of exploration and mining in Australia, whereas 20 years ago it was not. The author has been involved in dealings with Aboriginal groups over this period. The following paper is a summary of the social background to such dealings and a compendium of rules for the newcomer to this aspect of the resource industry.

When a fire or explosion occurs underground the ventilation maybe disrupted and the atmos- phere may become oxygen deficient and filled with noxious and flammable gases. The basic survival technique for:any man alive underground is to escape and this may be achieved and rescue workers may enter such atmospheres to carry out rescue work underground by using appropriate breathing apparatus.
