The Australian coal industry future developments

Abstract Australia's prosperity relies significantly on income generated from exports of resources and agricultural products. In 1989-1990, coal was Australia's most valuable export commodity, contributing A$5.7 billion or 14% of all export income.
The abundance and quality of its coal resources and the proximity of Australia to the rapidly developing economies of Southeast Asia were significant factors that encouraged export-oriented growth and investment and will continue to do so. On the other hand, the 1980s highlighted the sensitivity of the industry to international changes in supply and demand, currency and socio-political forces.
Following many years of disappointing returns for investors, mainly as a result of falling Australian dollar coal prices, resolve will be necessary to maintain competitiveness with resource-rich nations. In recent years, operators, unions and governments have begun to embark on a long overdue rationalization of domestic issues in a bid to increase productivity and reduce costs.
The nature of mining operations is also changing; deeper surface mines and the growth oflongwall mining will require the development of new technology and skills. Other challenges emerging from the international environmental debate will require that Australia responds appropriately to demands for cleaner fuels, energy efficiency and environmental responsibility.
The future development of the Australian coal industry will therefore be influenced by its own ability to become more efficient and mature in the production of quality coal products and through rational international response to environmental questions.

Summary: At Teck-Corona Operating Corporation's David Bell Mine, a successful -water quality management strategy has been established. This resulted from the development and application of process technology, allowing year round discharge of an effluent exceeding the chemical and biological standards set by the Ministry of Environment. This strategy aims at minimizing contaminant levels of effluents through optimization of reagent selection and reduction of effluent volumes through maximizing reclaim...

Summary: This paper is a brief overview of the role of oxygen in cyanide leaching of gold feeds (e.g. ore, concentrate). As the majority of gold occurs in the elemental state (Au°), its oxidation is of vital importance for dissolution in the cyanide lixiviant. The cyanida-tion at high pH is favourable for the oxidation of Au° with a mild oxidant such as air or oxygen. Beside oxidation of gold, deleterious effects of soluble sulphides, arsenates, antimonates on cyanidation of gold can be...

Summary: A scientific testing program, sponsored by the Mining Industry Research Organization of Canada (MIROC), was undertaken on the surface and underground facilities of Inco's Crean Hill Mine to investigate the effectiveness of using dry drilling with a dust control system.
The surface test work consisted of the monitoring of advance rates and bit life while a series of 165 mm holes, wet and dry, were drilled at both mine air (0.69 MPa) and high pressure air (1.72 MPa). The results, based on...
