A full-blown armada of technical means was committed to the development work. Winning of the uranium-bearing rock was by blasting work: blast holes were drilled in the rock, and the subsequent blast fragmented the rock material. The ore-bearing rock was then hauled away. At times, more than 150 vehicles were committed to the haul job. The trucks used were of Soviet manufacture: SIS of 3 tonnes capacity at the beginning, KRAS of 12 tonnes capacity later. Such payload pales in comparison with the off-highway trucks used by Wismut GmbH today in the framework of open pit backfilling and which carry up to 136 tonnes. Dumping of the waste rock was by conveyor belts and stackers.
Remediation of the former Lichtenberg open pit mine by Wismut GmbH will safely enclose more than 125 million cubic metres of waste rock in the emerging landscape structure.
The twin-mount fill body will continue to call to mind the region's former mining activities. On the occasion of the national horticultural exhibition held in 2007, the "New Ronneburg Landscape" was presented to the public. The specific architecture is to make future visitors to the region aware of the efforts and achievements of Germany's largest environmental restoration project as well as of bygone mining operations.
