As shaft construction experts, we not only carry out repairs by refurbishing shaft installations, but also shaft backfilling, roadway driving and cable replacement. We also specialize in the planning and installation of shaft pipelines and cables.
After shaft operation has ceased, the shaft tubes must be permanently sealed by installing watertight and gas-tight systems. The shaft tubes form the connection between the surface and the mine workings.
The professional backfilling of the shaft tubes provides long-term protection for the surface, the groundwater horizons used and the mine workings.
The shaft is the eye of the needle in a mine. It is the connection between the mine workings and the day-to-day operations. Not only are the necessary machines, equipment and materials transported underground through the shaft , but also the personnel responsible for operating the mine. Raw materials are also conveyed to the surface via the shaft .
An essential component of these conveyor systems are the ropes to which baskets or skips (conveyor vessels) are attached. Due to the high loads, these ropes are subject to strict inspections and must be replaced regularly to ensure safe and efficient operation.
As experts in shaft construction , we handle rope replacement on almost all conveyor systems - reliably, safely and to the highest quality standards.
Modern day shafts are not only used to transport material and personnel by means of conveyor systems, but also supply the mine operation with important resources such as pipelines and cables.
Due to the long distances underground, the shaft cables must be particularly robust and large in size. These heavy cables are installed using special winches. Our experienced shaft sinkers carefully supervise the process and professionally attach the cables to the designated anchoring points.
In contrast to shaft cables, shaft pipelines are more variable in their form and use. They can supply the mine with water, diesel or similar consumables. It is also possible to transport backfill or residue products from surface facilities via shaft pipelines. The installation of new pipelines always requires thorough and precise planning.
We offer you a comprehensive service: from technical planning and support with approval procedures to the professional installation of pipes in your mine shafts.
In order to ensure smooth transportation and an optimal connection of the mining fields to the other mining operations and the shaft , the excavation of roadways is unavoidable. This work can be carried out either conventionally using drilling and blasting technology or mechanically using roadheaders.
We have a modern fleet of equipment and use our own machines if required. Alternatively, we can also implement the project individually using the customer's own machines or new machines procured in-house.
Securing pit structures is another central component of our services. This includes the installation of various support elements such as adhesive anchors or expanding sleeve anchors. We also offer subsequent securing by installing reinforced concrete shells using shotcrete technology.
Soil freezing is one of our core competencies in shaft, civil engineering and tunnel construction. This environmentally friendly process effectively secures and seals water-bearing soils and loose soils.
Existing shafts are up to 100 years old and are exposed to a variety of loads. Despite durable construction methods, they are subject to natural wear and tear. We know the typical damage patterns and offer customized solutions for renovation, conversion and extension.
Taking all relevant factors into account, we prepare feasibility studies and analyses and derive well-founded time and cost estimates. From approval to execution, we guarantee efficient planning in accordance with applicable standards in Germany and abroad. We ensure sustainable solutions through innovation and development.
Whether conventional or mechanical, on a pilot hole or full face sinking - we bring your shaft safely and on schedule to the final depth.
