Mucking
Power Mining provides excavation and drilling services for underground rock construction. Our special expertise lies in vibration-sensitive urban infrastructure projects, both new builds and rehabilitations, as well as mine development drifting in underground mining.
Efficient and safe handling of rock material in mining and tunnel environments. Power Mining delivers scaling and loading as part of our complete rock construction services.
Scaling: mechanical and manual
Scaling removes loose rocks and boulders from blasted surfaces to maintain safe working conditions. We handle this work either mechanically or manually, depending on what the plans require and what the site conditions demand. Final surfaces and areas requiring support typically need manual scaling to achieve the right finish.
Mucking
In tunneling, mucking means clearing the rock material from the tunnel face after blasting using excavators or wheel loaders, then moving it out for transport. Loading and mucking are usually the longest phase of excavation, so we focus on keeping these operations running smoothly to stay on schedule.
Complete tunnel construction services
We perform scaling and loading as part of our full-service approach: Power Mining handles every phase of tunnel construction, integrating them into one continuous operation. This gives you an efficient, safe, and cost-effective solution for your project.

Mining
At infrastructure and mining sites, we work in tunnels ranging from large tunnel profiles to small widening/roof-raising projects, as well as production mining. Shaft sinking based on the longhole or Alimak method.
We have solid expertise and equipment for tunnel excavation. We have several years of experience in using electronic detonators on a daily basis in vibration-sensitive areas.
Our personnel have a long pedigree in shaft excavation for mining and infrastructure projects. We take an innovative approach to digging shafts in challenging locations.
Includes hydraulic splitting on difficult sites.
Rock reinforcement
Infrastructure projects: full range of rock reinforcement and shotcreting, using a shotcrete robot, rockbolting, wire-mesh reinforcement. We also do manual drilling, wire-mesh reinforcement, and shotcreting on small sites.
Mining sites with our own machinery: cable bolting, wire-mesh reinforcement and all types of rockbolting.
Scaling
In infrastructure and mining projects, we handle scaling both mechanically and manually.
The method is chosen based on the requirements of each site: final surfaces and areas to be reinforced typically require manual scaling to achieve the best result.
A safe working environment is ensured by thoroughly removing loose rocks and boulders before proceeding to the next stages.Mucking
In tunnel construction, we handle mucking using excavators or wheel loaders, collecting and transporting the blasted rock for further haulage.
Efficient mucking keeps the project on schedule, as it is typically the most time-consuming phase of the excavation cycle. The service is delivered as part of our full-service offering, integrating all stages of tunnel construction into one seamless package.
Grouting
Rock grouting is an essential part of safe and sustainable tunnel construction. It is used to reduce the permeability of the rock and improve its sealing properties. The goal is to prevent water migration within the rock mass, which extends the service life of the structure.
