Mining Technical Services.
Determination & Persistence
With our combination of knowledge and experience, our technical team can provide the determination and persistence your operation needs to thrive in the tough times as well as the good.
Our services include geotechnical and geological mapping, strata hazard identification and preparing reports that can assist in the mine planning process.
We support the onsite geology and geotechnical teams with the day-to-day processes essential to running a safe and productive underground mine.
Geological Mapping & Support Auditing
Regular development mapping and support auditing is critical in ensuring geological hazards are reported in a timely manner and ensuring they are effectively controlled.
- Geological and geotechnical logging and sampling of soil and rock material in accordance with various industry standards (i.e., AS 1726:2017 and CoalLog)
- Field geomechanical testing (i.e., point load testing; dynamic cone penetrometer (DCP); field slaking, swelling, and dispersion testing; pocket penetrometer and torvane testing)
- Management of laboratory geomechanical testing programmes for soil testing: Atterberg limits; particle size distribution; California Bearing Ratio (CBR); soil triaxial (UU, CD, and CU)
- Management of laboratory geomechanical testing programmes for rock testing: Uniaxial compressive strength (UCS); rock (Hoek) triaxial; indirect (Brazilian) tensile strength; CERCHAR abrasiveness index; slake durability index
- Geotechnical supervision of test pit excavation, geotechnical drilling, shaft construction
- Geotechnical and hydrogeological instrumentation installation and monitoring

Development Fault Drivage
When a development unit encounters adverse geological conditions or structured strata - our people can provide your technical services team a clearer picture of the situation. With a clearer picture there comes confidence.
Our team's ability to perform accurate fault analysis can provide a detailed representation of the intersected fault structure(s).
Improved assessments in the length of grading sequences can be done with richer information, and this can lead to a minimisation in stone dilution and improve the marketable product to the mine’s customers.
With a deeper knowledge of the structures, that inherit real-world geological information - it is possible to make informed choices about the development of your mine.

Longwall Fault Drivage & Reporting - Planning
From interpreting the existing modelled and real-world data to producing detailed drawing documents - we have the planning processes covered.
The services we provide during a longwall’s planning stage are extensive and include everything a longwall planning team would require before the going gets tough.
- Generation of proposed longwall flight plans, and advising the technical leadership on the planned mining horizons whilst ensuring efficient and safe coal extraction
- We provide regular mapping and inspection reports throughout the fault drivage process
- Steering a longwall through a fault is an operational challenge, let our technical staff assist your team with cross sections profiles, longwall stance diagrams and more…

Longwall Fault Drivage & Reporting - Operational Processes
We are in constant contact with the longwall operations team throughout the entire fault drivage process. This guarantees an effective information flow and a safe and productive longwall panel.
Specialising in developing the procedures, conducting the regular inspections, providing detailed reporting, and advising on critical aspects of the operational process of any fault drivage scenario is our key to providing you and your team with confidence.
