SST History

Being totally independent, SST started as a spin-off from RWTH Aachen University. The company was founded in 1991 by Mining Professor Rolf Dieter Stoll, Dr.-Ing. Fritz Schwarzkopp and Prof. Dr.-Ing. Walter Thiels. In 1993 Mining Engineer Axel Emons joined the company as shareholder and third CEO.
In 2019 Senior Mining Engineer Martin Buschmann and Senior Geologist Dietmar Quante joined as managing directors. On 11 March 2023, Dipl.-Ing. Daniel Bähren (Head of Mine Surveying) and Sebastian Loyen M.Sc. (Head of Mining Planning) were appointed as authorized signatories. Both decisions guarantee continuity for the future especially in services and client relations.
Following the former founders in mid-2024, Dipl.-Ing. Martin Buschmann and Dipl.-Geol. Dietmar Quante are now the sole shareholder and CEOs.
