For over a century, Sika has been involved in highly challenging tunneling and mining projects around the globe. Sika supplies solutions for the largest and technically most complex projects - from below the Atacama Desert in Chile inside the large Chuquicamata block caving mine to the Gotthard base tunnel 2,500 meters below the Swiss Alps.

Cost overruns and not matching the designed throughput rates are a common thread for mining operations, especially when ore is sourced from underground. Our concrete and shotcrete technologies contribute to efficient mine construction under a suite of climatic conditions. Sika concrete admixtures such as our Viscocrete® and Sigunit® technology stands up to the highest quality and HSE standards in operations all around the globe. Furthermore we offer a full product range.

Yielding Underground Support with Sika Fiber Technology

Yielding primary shotcrete liners have become the standard underground support in many mines around the globe. Increased stress levels in deeper mines require a yielding support in order to take up dynamic loads and seismic shocks from the rock mass. Sika Fibers are high quality, macro-synthetic fibers used in underground projects around the globe and proven to outperform steel-fibers when it comes to energy absorption and cost-performance of the shotcrete support.

Sika Fiber Force

Sika® Fiber Force is the macro-synthetic fiber product range from Sika. The Sika fibers provide excellent yielding characteristics within the shotcrete liner or specific concrete structures such as slabs and piles. The fibers can be sourced in different packaging options including handy fiber-packs that easily dissolve in the wet concrete mix.

Optimize Your Shotcrete Mix

Macro-synthetic polypropylene fibers have become the standard in many mining operations around the globe. Macro-synthetic fibers have a few key advantages compared to steel fibers including avoidance of corrosion, much lower dosage (on a per weight basis), much better yielding characteristics, easier handling and better overall price performance.

3. Mine Paste Backfill Admixtures

Admixtures to Optimize Paste Backfill Operations

Sika offers a wide range of mine paste backfill admixtures that can be dosed directly into the wetted out mix of the paste plant. The admixtures are based on the proven Sika PCE technology and can have a dramatic effect on the rheological behavior of the paste. The admixtures act as a high range water reducer and therefore provide the opportunity to significantly reduce the cement consumption of the paste operation. Sika is in position to provide extensive on site support and to support you with the right paste backfill design.

Learn How to Optimize Your Mix

Optimize Your MixSika applies similar principles that we use in concrete also for mine paste backfill plants worldwide using our chemical toolbox that has been refined over the past decades. We can help you to achieve the following with your backfill paste:

  • Reduce binder consumption
  • Improve compressive strength
  • Reduce bleedingFacilitate paste pumping
  • Reduce wear and tear of machinery and paste lines
  • Speed up mine and fill cycle time
     
Customized Solutions

Every mine paste is different in terms of its granulometry, the chemical composition and the binder types used. Sika is experienced in analysing the different pastes in order to find the admixtures that will suit your paste best. By doing so,  we are in position to deliver the competitive edge when it comes to cost reduction and mix optimization.

Onsite Support

With our presence in more than 90 countries we are in position to give you  dedicated and efficient on site support to optimize your paste fill operation. Specialized teams in all world regions will give you the support you need to improve the cost performance of the paste backfill mix.

5. Dust Sealers

Don’t Get Lost in the Dust

In most mining environments, dust represents one of the highest health and safety concerns no matter if the operation is located under- or above ground. Therefore, a lot of effort is put into reducing dust generation to an acceptable level, on a daily basis. Sika Dust Seal®-300 is a new product from Sika, that prevents dust particles going airborne and reduces dust generation over an extended time period. The product is fully bio-degradable and is diluted with water prior to application.

Learn How to Minimize Dust Generation
Dust

Dust generates all sort of problems, ranging from health and safety concerns due to reduced visibility and respiration issues to increased wear and tear of machinery and equipment and increased ventilation costs in underground workings. Sika Dust Seal-300 is designed to provide a safe, water based and environmental friendly alternative to current dust-sealing solutions.
