The Missing Link - Forensic Engineering
As part of a subsidence assessment and other mining approval process requirements for a multi-seam mining operation, SCT has undertaken research in the reliability of the historical mine plan records for this triple seam site.
The purpose of this research was to identify areas of potential, marginally stable pillars to assist in quantifying residual risk for greater than predicted subsidence and to assist in considerations for a Principal Hazard Management Plan to manage the risks to health and safety from subsidence. Key to quantifying the risk to natural or built features and health and safety is an understanding of the status of the overlying goaf areas in the old workings stretching from about 1880 to 1950.
Pike River Mine Re-Entry Update
On the 17th of February 2021 the Pike River Recovery Agency reached the roof fall in the Pike River Mine Re-entry project. SCT personnel, including Stuart MacGregor and Chris Lee, have been working closely with the PRRA and other technical experts towards this significant milestone. This is the culmination of three years of planning and execution.
Pike River Mine Re-entry - Recovery Process Begins
The Pike River Recovery Agency has embarked on the Drift Recovery Phase – with the initial manned re-entry to the mine taking place on Tuesday 21st May.

SCT, CSIRO and LKAB Conduct Hydraulic Fracturing Trial in Sweden for Reduction of Mine Seismicity
A team of SCT Engineers led by Dr Rob Jeffrey and Dr Ken Mills travelled to Sweden in May to undertake the first full-scale hydraulic fracturing trial at LKAB’s Kiirunavaara Mine in Northern Sweden. The SCT team consisting of Dr Rob Jeffrey, Dr Ken Mills, Jesse Puller and Kenny Mills worked collaboratively with a team from CSIRO’s Melbourne hydraulic fracturing group and a select group of Engineers from LKAB’s R&D, project and operational rock mechanics departments.
Rib Deformation ACARP Study
SCT have completed successful instrumented rib monitoring programmes at two mines as part of their rib deformation ACARP study
SCT are proud to work with a leading mining house in Sweden
One of our Senior Engineering Geologists, Jesse Puller, recently conducted several underground overcore stress measurements at LKAB's Kirunavarra Mine in Northern Sweden. The project forms part of an ongoing campaign between SCT, LKAB and CSIRO which uses our new wireline deployed downhole logger technology to measure 3D in situ stress.
