2. Shotcrete and Equipment
Speed Up Cycle Times with Sika Shotcrete Technology
In cycle shotcreting is key for rapid mine development and fast cycle times in mines around the globe. We offer fully integrated custom solutions for wet and dry shotcrete. In addition we offer an integrated range of shotcrete equipment for all applications.
Pre-packaged Shotcrete mixes
With its 35 years of proven track record, the King® brand has been a force in the canadian mining industry.
- Custom pre-mixed dry or wet shotcrete products
- Solutions to work safely in the harshest conditions
- Products developed specifically for permafrost applications
- Logistics for remote mining operations
Sika Sigunit® Technology
For many years, the Sika Sigunit® shotcrete accelerators fortify underground structures across the globe. Dedicated to delivery high early strength shotcrete and adjusted to the specific cements in use, Sika is in position to help speed up your mine cycle times and to facilitate the shotcrete handling significantly.
Yielding Underground Support with Fibre 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. We offer two solutions for fibre reinforcement:
1. Fibres can be added to your shotcrete King branded product upon request, providing a custom mix ready for use.
2. Fibres can be purchased separately and added on site to your mix.
We work closely with our partners and offer in depth on-site support to bring the application and quality testing of the shotcrete operation to the next level.
Reliable Equipment Dedicated to the Mining Industry
Sika Aliva® is the Sika equipment manufacturer for Shotcrete equipment of all sizes. Specialized in high quality, compact rotary machines, the spray units are ideal for shaft sinking, in cycle shotcreting of smaller drift diameters and rehabilitation and refurbishment works. The equipment is designed for a modular build-up to serve each customer's specific needs.
Sika Aliva® Longlasting Quality
Sika Aliva® shotcrete equipment is used in mines all over the globe. From the deep Canadian cut and fill operations to narrow epithermal shrinkage operations in Mexico and Asia, Aliva equipment is reliable wherever and whenever you need it. The equipment is especially designed for operations where access is difficult and small, equipment is of use due to smaller drift diameters. The equipment can be used for dry and wet spraying.
Assembled According to Your Needs
Due to the modular set-up of the Aliva spray systems, the spray rigs can be customized according your needs. The «carrier independent system» or «CIS» allows to combine the different modules based on the needed output volume, the carrier of choice and the accessibility of the sprayed areas.
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 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.
Optimize Your Mix
Sika 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 bleeding
- Facilitate paste pumping
- Reduce wear and tear of machinery and paste lines
- Speed up mine and fill cycle time
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.
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.
4. Grouts and Injection
Whether your work consist of cable bolting, earth tie-backs for soil stabilization, grouting anchors or re-bar grouting, Sika has the grout suited to your mining application.
Sikafix® Injection Range
The Sika two component injection resins are dedicated to stop water and to consolidate challenging rock conditions underground. The products are applied using two component piston pumps of different sizes and auxiliary equipment such as packers, and lances. The PU resins can be accelerated based on the reaction time needed to counter the water ingress and to avoid washouts.
Successful pre and post grouting of underground structures warrant good preparation and assessment of the specific situation on the job-site. Dedicated and specialized Sika teams help you to achieve your goals and to train your teams when using the injection resins and auxiliary equipment. We also offer customer trainings that take place frequently.
