Dolomite and rock filling mining

Underground dolomite mining and rock backfilling at the Wellen site

Underground mining of dolomite rock

At the Wellen site, the raw material is extracted via underground mining. The mined dolomite rock is then processed and made available for further use in various industrial sectors. The site forms part of the PORR Group’s raw material extraction and processing operations.

Raw material for various industrial sectors

The extracted dolomite is used as a raw material for applications in the building materials industry, as well as for industrial processes in the chemical and fertiliser industries. Processing is carried out in accordance with the requirements of the respective areas of application.

Mine backfilling as part of underground operations

In addition to raw material extraction, TKDZ GmbH’s range of services includes so-called mine backfilling. This involves filling mining-related voids with suitable backfill materials. The backfilling serves to secure mine chambers as well as to stabilise areas of underground mining.

Use of backfill materials

The backfill materials used are materials generated by the mining operation itself, which are produced during the extraction and processing of dolomite rock. In addition, approved non-mining materials are used for this purpose. The selection of backfill materials is carried out in accordance with mining law and regulatory requirements governing the operation of the mine.

Securing the mining chambers

Backfilling the voids is carried out primarily to stabilise mining chambers and to secure the roof. Furthermore, backfilling helps to stabilise areas where the mining pillars are subject to additional stresses. These measures form part of the mine’s day-to-day operations.

Basis for raw material extraction

Underground dolomite mining and the associated backfilling works enable the extraction and supply of raw materials for various industrial sectors. These measures serve to maintain mining operations at the Wellen site.
