The subject `access to land' is often seen as an item high on the list of matters of concern to mining interests not only in New South Wales but throughout the whole of Australia and other countries. Just what are the problems/issues of access to lands today? What is being done about them? What can be achieved? What is practical to achieve? And where does New South Wales sit in relation to all this? These and a range of other issues are addressed in this paper.

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.

The expense of mine environmental and planning process approvals is a fundamental and proper part of mine planning and feasibility costs. It is not a cost that should be the subject of challenge nor is it a cost that should be avoided. However the additional process approval costs incurred by bureaucratic delay, process duplication and administrative incompetence is a scandal and a deterrent to investment.

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.

This report on the 5th International Conference on Underground Space and Earth Sheltered Structures, which was held at the University of Technology, Delft, the Netherlands, on 2 to 5 August 1992, was submitted to the members of the Australian Underground Construction and Tunnelling Association. The report describes the conference themes and outcomes and puts forward some observations about a growing world-wide interest in the promotion of appropriate uses of underground space. The report recommends the creation of an Australian centre for research to bring together a wide range of professional disciplines and to focus attention on the potential benefits of using underground space.

A computer programming language known as GPSS is described and possible applications for the mining engineer are presented. The language is continually being upgraded with improved versions appearing about every three years. The tremendous power of the language is considered by comparing it with standard engineering programming languages, such as Fortran or Basic. Sample problems that can be solved using the language are indicated. The advantages and disadvantages of the languages are also discussed.

A method is proposed for the analysis of tin in cassiterite ores. Tin is volatilised by heating with ammonium iodide. The tin iodide so formed is extracted with hydrochloric acid and the concentration is measured by atomic absorption spectroscopy using an air-hydrogen flame.It is considered that a more efficient extraction of tin and faster reproducible results are obtained than by any other known method.

The Century zinc deposit is located in Queensland approximately 250 kilometres north north-west of the provincial city of Mount Isa, on Lawn Hill Station and within 150 kilometres of the Gulf of Carpentaria.ThefirstMining Lease in this area was pegged in 1887. The Silver King vein is the largestvein deposit in the area and has produced lead and zinc, in addition to 74,000 ounces of silver during its history.A total of forty three veins containing silver, lead and zinc are now known, all of which were discovered by prospectors within 10 years of the first vein being recognized.

The mining industry is a relatively minor user of water, which has historically been largely soured from private schemes. Frequently mines are often located in areas with limited available water resources. Water reform is increasingly affecting access to water for new mining projects and mining companies are being required to consider the value of water and the implications of reliability in their planning. This paper seeks to briefly review the water reform process in Australia and how it is affecting the mining industry with reference to some recent project experience.

Away from past controversial presentations, a matter of fact, intuitive and simplified approach to the Theory of Sampling (TOS) sampling variance prediction formula is offered which gives an insight on the type of model required for the liberation factor, the practical limitations of such model and methodological principles for its calibration. This paper intends to see what happens in TOS when trying to go from the very simple towards the full level of real life complexity, and actually tries to answer the question: Is there such a thing as a æsimpleÆ TOS?

Numerical modelling is a valuable tool for simulating the fundamental processes that take place during a heating. The models presented in this paper have enabled a quantitative assessment of the effects of initial pile temperature, pile size and mass and coal particle size on the development of a heating. All of these parameters have a certain criticality in the coal self-heating process.

The design of the grinding section is discussed and details are given of the equipment installed for the autogenous grinding of ores from the C.S.A. mine at Cobar.The first section of the concentrator commenced treating ore in June, 1965 and operating experience and maintenance requirements since that time are outlined.

Mine planning for ore recovery by open stoping and pillar recovery is becoming more sophisticated, but there are basic operating constraints which must be imposed if this planning is to realise the production results on which the mine is dependant. The production reliability of an open stope is usually a high priority and common design problems can be identified. A range of practical considerations which should be considered at the mine planning stage are reviewed including equipment performance, blasting technology, ventilation requirements, development layouts, lead time, ground conditions, support, backfilling and ore recovery.

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.

Arm Royalty systems of different types are used throughout Australia by both state and federal governments to raise revenue and thus facilitate in the proper distribution of mineral wealth. Royalty systems should be neutral and equitable but by their very nature these objectives are impossible to obtain. Because of the individual nature of mineral deposits, in particular variable cutoff grades and tonnages, governments should be aware of the possible trade off between short and long term gains of the particular royalty scheme introduced.

More than 1000 Ian of seismic reflection data correlated to ten exploration wells along with geological, gravity and magnetic data are used to construct the subsurface structure, in particular the crystalline basement, along a corridor approximately 100 Ian wide that traverses central Iraq in SE-NW direction for a distance of about 500 km from Baghdad in the central part of Iraq to Dohuk near the Turkish border. This transect is one of few such transects that represents the Iraqi contribution to the Global Geoscience Transects (GGT) project. The transect crosses two out of three major tectonic elements of Iraq: the unfolded zone and the folded zone.

The Airport Link Railway utilises innovative solutions to a number of issues associated with underground development and transport infrastructure planning. It is typical of the major change underway in the countryÆs rail and air transport industry. It involves the private sector providing transport facilities in competition with the public sector, a convergence of planning and transport imperatives, the use of the most technologically advanced engineering practices to minimise construction impacts on the community and a commercialised way of developing and maintaining railway infrastructure and services.

Preparing for automated sample preparation has two facets; the need for better procedures as seen by the laboratory Manager and the approach to be adopted as envisaged by the equipment manufacturer. Both have many options and during the 1990s some at least of these options will be tried. As automation of sample preparation is only just beginning, can it be said that there is a real need for better procedures. What does automated sample preparation have to offer? Does it have real advantages or is it just a marketing tool to sell equipment?

In the face of intense global competition and other business pressures on coal miners, ongoing quality initiatives and continuous process improvements are needed to enhance business performance. By viewing a minesite in terms of key processes, rather then departments, and employing innovative technologies and better applying organisational resources, there exists enormous potential to achieve reductions in process cost and time.
