As the first phase of their Kidsmart programme in the UK, IBM donated a total of 27 of their Young Explorer Early Learning Centres, complete with Edmark educational software to 14 nurseries in 1999. These Early Learning Centres were initially developed by Little Tykes to serve the needs of 3 to 7 year olds and the Kidsmart aim has been to support early childhood educators in their efforts to apply this new technology to stimulate the development of children's social and cognitive skills. The UK initiative has also involved the British Association for Early Childhood Education (Early Education), who have …
New Legislative Framework And The Role Of Geotechnical And Gas Drainage Professionals, I. Anderson
New Legislative Framework And The Role Of Geotechnical And Gas Drainage Professionals, I. Anderson
Resource Operators Conference
In recent times legislators have moved away from prescriptive legislation to duty of care models. Such a move places employers and consultants under a need to demonstrate due diligence in the exercise of their functions. The principle legislation under which the coal industry operates is the New South Wales Occupational Health and Safety Act. This Act has substantial punitive measures including fines and imprisonment. The Department of Mineral Resources has developed and implemented an Enforcement policy which includes a prosecution element.
These changes necessarily impact upon key industry personnel including:
i) Mine Managers
ii) Internal Consultants - Company Engineers
iii) …
How Nsw And Queensland Coalfields Differ - What We Need To Do Better, B. Nicholls
How Nsw And Queensland Coalfields Differ - What We Need To Do Better, B. Nicholls
Resource Operators Conference
There are obviously similarities and differences between NSW and Queensland underground coal mines. The major differences are related to rock strengths, stress regimes, location and operational approaches. Issues relating to these factors are addressed, with some suggestions as to how underground coal miners can do some things better to improve efficiencies and returns on investment. The differences are many and varied. Some factors having a major bearing on mining efficiencies are discussed, with some examples of failures and successes being outlined.
Gas Emission Modelling Of Gate Road Development, R. J. Williams, E. Yurakov, D. J. Ashelford
Gas Emission Modelling Of Gate Road Development, R. J. Williams, E. Yurakov, D. J. Ashelford
Resource Operators Conference
This paper covers the modelling of gas emission during gate road development. Complexities related to the range of gas reservoir and mining data are briefly described. The rib emission response to initial gas reservoir parameters is defined using the SIMED II gas reservoir simulator. The rib emission decay curves are then used in an interactive EXCEL spreadsheet model that takes additional account of mining and ventilation parameters. It is an attempt at bringing to planners and mine operators an interactive tool that incorporates the important parameters and options.
SIMED’s strengths lie in it’s ability to:
• quickly convey a message …
Longwalling And Its Impact In The Southern Coalfield - Recent Bhp Experiences, P. Eade, J. Wood
Longwalling And Its Impact In The Southern Coalfield - Recent Bhp Experiences, P. Eade, J. Wood
Resource Operators Conference
Illawarra Coal BHP Minerals currently operate five underground coal mines in the Southern Coalfield of New South Wales in Australia. Each mine operates a retreating longwall extraction system as the primary production process. Economic reserves at several of the mines are nearing exhaustion and a feasibility study is under way to maintain production levels by development of a new mine. The level of maturity of the current operations and the nature of the remaining coal reserves in the Southern Coalfield present significant challenges for continued viable longwall mining. A general overview of the challenges and recent BHP experiences in relation …
Towards High Productivity Under A "Claystone" Roof: Great Northern Seam Support Management Experiences At Chain Valley, Moonee And Wallarah Collieries, P. J. Hayes
Resource Operators Conference
Coal Operations Australia Limited Operates the Chain Valley, Wallarah and Moonee Collieries which are located in the Newcastle Coal Fields of New South Wales in the Catherine Hill Bay area approximately 100km north of Sydney. Operations are in the Great Northern seam, which until recent years were all conducted under an immediate roof of a strong conglomerate. Large areas of the current reserves at all operations are in areas of a “claystone” immediate roof. All three mines have attempted at various stages of their history to find an economic mining method under these claystone roof conditions, with varying degrees of …
Longwall Website For Australian Mining Conditions, N. Aziz, S. Chambers
Longwall Website For Australian Mining Conditions, N. Aziz, S. Chambers
Resource Operators Conference
The mining engineering course at the University of Wollongong is in the process of continuing restructuring to meet the challenges and changing demands on mining engineering education in Australia. An online interactive student resource on longwall mining has been developed at the University of Wollongong to supplement formal delivery of the subject material. The interactive website allows students to gain a deeper understanding of longwall mining in their own time and at their own pace. The website had been circulated to students and various industry quarters seeking their comments and advice for the future directions of this type of learning …
Successes And Future Challenges For Longwall Mining In Structured Ground, I. Stone
Successes And Future Challenges For Longwall Mining In Structured Ground, I. Stone
Resource Operators Conference
The experiences from the recent 3 years at Springvale Mine have highlighted once again the importance of understanding the geological structure at a mine site. Springvale Mine previously had a history of difficult roof conditions, although not clearly linked to geological structure. From mid 1998 a series of complex strike slip fault structures were encountered, one set running with and along the commencement of the 404 Panel gateroads. The unexpected faulting, its critical location, and unknown extent had a serious impact on panel development and business performance. Even the most carefully constructed business plan and budget is quickly damaged by …
Geotechnical Engineering At German Creek - A Historical And Sometimes Hysterical Review, M. Jakeman
Geotechnical Engineering At German Creek - A Historical And Sometimes Hysterical Review, M. Jakeman
Resource Operators Conference
The initial drilling exploration started in what we now know as the Bowen Basin coal region in the 1950’s, to open up and delineate the coal seams for the whole region. After Utah grabbed the easiest and more favorable large sandpits in the early stages, other companies started to understand the opportunities for the future. In 1979, German Creek started construction and operations at the end of the boom and bought four draglines. This paper presents the geotechnical experiences at German Creek over 21 years of operations. Today, the operation sustains one dragline, two underground longwall operations and another underground …

Early Days Of Rock Mechanics And Strata Control, J. Enever
Early Days Of Rock Mechanics And Strata Control, J. Enever
Resource Operators Conference
BHP/AIS's Rock Mechanics and Strata Control (RM & SC) Group was formed in the late 1960's to address a range of issues then facing BHP/AIS's underground coal mining operations. Building on a local tradition of innovative rock mechanics and a global body of research targeted at sedimentary strata behaviour, RM & SC tackled a number of critical areas and made substantive contributions in all of these. Alan Hargraves, as the leader of the group, had a significant influence on all activities, as well as continuing personal research in the area of seam gas management. A direct line can be traced …
Outbursts - Management And Control, J. Hanes
Outbursts - Management And Control, J. Hanes
Resource Operators Conference
This paper summarises some of the development of the understanding and management of outbursts in Australia, reviews the current situation and provides some thoughts on necessary research and development. It cannot be and is not comprehensive. Outbursts are better understood, prevented or controlled than they were 20 years ago. This is partly a result of the considerable amount of research into and documentation of outbursts and gas by a relatively small group of outburst pioneers supported by the coal industry. The result has been fewer outbursts in general, and the safe mining through a few potential outburst zones without risk …
Gas Drainage Practices, L. W. Lunarzewski
Gas Drainage Practices, L. W. Lunarzewski
Resource Operators Conference
Coal seam gas problems, largely “gas-outs” and instantaneous outbursts of coal and gas, have created serious difficulties for the coal mining industry around the world. Typically, a single longwall face is now capable of producing an average 10 000 to 15 000 tonnes of coal per day. The total quantity of gas released in gassy mines could conceivably reach 5000 and 8000 litres of gas per second per single longwall block and for the total mine respectively. The introduction of various gas drainage techniques in Australian gassy mines was necessary to complement ventilation systems and to satisfy the statutory gas …
