About Mt Arthur South:
Located five kilometres south of Muswellbrook in the Upper Hunter Valley of New South Wales, Mt Arthur Coal is an open cut mine, producing thermal coal.
Thiess has supported BHP at Mt Arthur Coal since 2017, first providing load and haul services and then additional mining services, including mining overburden and coal, mine design, planning and scheduling services and drill and blast operations at the southern end of the operation.
In 2019, BHP expanded its agreement and the scope of Thiess’ operations to include statutory responsibility for its operation as mine operator of the southern end of the Mt Arthur Coal operations (the Ayredale and Roxburgh Pits).
Thiess has a long history in the Hunter Valley (dating back more than 80 years) and provides mining services at three mines, including Mt Arthur Coal.
Committed to offering full-time employment options in the region for employees, Thiess has a proven track record working with both the community and local suppliers.

Aim of the Workshop:
Tomorrow’s geotechnical engineers, surveyors, planners, and managers are all data scientists with access to large sets of remote and local sensing data. InSAR data and derived information are increasingly being used in asset and risk management in mines and tailings storage facilities—whether operational or closed. This places new demands on engineers’ technical understanding since the InSAR data shows that everything in the mine is moving continuously.
By inspecting the InSAR data routinely and detecting patterns of the surface deformation associated with patterns in the use of the mine’s infrastructure, early detection of problems comes within grasp, and risk can be mitigated more effectively by separating the geotechnically relevant signal from geotechnically irrelevant noise. Understanding remote sensing data sets becomes a strategic enabler. This technical workshop provides participants with an understanding of optical, SAR and InSAR remote sensing measurements and deployment for asset/risk management, including practical cases.
Workshop Objectives:

Understand the basics of InSAR deformation maps, the opportunities they provide and their limitations
Recognise the applications of InSAR in the Mining Industry
Learn from Real-World Case Studies

BOHOGS Moranbah Technical Meeting on Geotechnical Issues In Coking Coal Stockpiles
2024-10-22 12:00 - 18:00
BOHOGS will be hosting a Technical Meeting in Moranbah on Tuesday the 22nd October 2024. Dr John Eckersley will be presenting two sessions on “Geotechnical Issues In Coking Coal Stockpiles” aimed at Geotechnical Engineers, CHPP Superintendents, Stockpile Supervisors & Coal Metallurgists.
Please forward this event on within your company to CHPP Superintendents, stockpile supervisors, CHPP operators and coal metallurgists, or whoever you’d think would benefit from this event!
Event Outline:
This will be a 2-session event presented by John Eckersley, a retired geotechnical engineer, and author of the ACARP Report on coal stockpiles (C4057 – “Moisture changes & stability problems in coking coal stockpiles”, June 2000). It will mostly relate to coking coal stockpiles (but not exclusively, since there is now evidence that washed thermal coal with sufficient fines can suffer similar problems).
Coal stockpile slips presenting serious risks were first observed at Hay Point in the early 1970s and continued to occur at port stockpiles until at least 1991. Since the early 1980s, they have become an issue at Coal Preparation Plant (CPP) product stockpiles with a fatality in NSW in 1987, and significant Bowen Basin slips as recently as 2018.
Date:
Tuesday 22nd October, 2024
Time: 12:00 to 3:00pm (Technical Meeting), with social drinks afterwards.
Light canapes and tea/coffee/soft drinks will be provided prior/during the technical meeting. Social drinks and canapes/refreshments will be provided post meeting conclusion at the bar.
Location:
Western Heritage Motor Inn
1-17 Mills Avenue, Moranbah QLD 4744
Agenda:

12:00 – 12:30pm: Registration and welcome
12:30 – 1:15pm: SESSION 1: CPP Superintendents, Stockpile Supervisors, Coal Metallurgists and Geotechnical Engineers
1:15 – 1:30pm: Questions & discussion, refreshments
1:30 – 2:15pm: SESSION 2: Geotechnical Engineers
2:15 – 2:30pm: Questions & discussion, refreshments
2:30pm onwards: social drinks/dinner (be confirmed once finalised)

Session 1: CHPP Superintendents, Stockpile Supervisors, Coal Metallurgists and Geotechnical Engineers
Session 1 will provide a general description of coal stockpile stability issues and their consequences, and especially sudden large rapidly moving flowslides. It will outline important factors in their formation, how to identify where they are likely, and potential risk reduction measures. It is designed for CPP Superintendents, Stockpile Supervisors, Coal Metallurgists and Geotechnical Engineers.
Session 2: Geotechnical Engineers
Session 2 will build on the information introduced in the first, with more technical description of factors that contribute to stockpile instability. It will discuss the data needed for meaningful analyses of moisture movements and stockpile slope stability, what is currently known, and aspects that require more investigation. It is primarily designed for Geotechnical Engineers, although others may also benefit.
RSVP:
To RSVP for the event, please email Dan Payne (dan.payne@bhp.com) before Friday 18th of October 2024. You can directly email Dan or use the buttons below.

Online Meeting:

The Presenter:
John Eckersley spent the first 3½ years of his career as geotechnical engineer at Goonyella Mine, returning to James Cook University in late 1980 to complete PhD study. He then spent 17 years lecturing in civil and geotechnical engineering while also researching coal stockpile stability and moisture issues. John left JCU in early 1998 and spent the remainder of his career in geotechnical consulting, working for Coffey (1998 – 2017) and then AECOM (2017 – April 2019). Since retiring he has attempted to tidy up some unfinished business in our ability to conduct meaningful seepage and stability analyses of coal stockpiles. This work was published in three papers in Australian Geomechanics in 2022 and 2023.
