About Rock Solutions
Rock Solutions North AB is a product development company focusing on safety, efficiency and quality in mines.
The prototype, that later become EXI-bolt, was originally designed in 2012. It was a result of studys in unoptimized mounting procedures of rock bolts where the handling (preparation, injection and cleaning) of the cement was very time consuming. EXI-bolt as a product eliminates that with its unique features reguarding quick mounting and dynamic metal quality. EXI-bolt can also be used to indicate the force on the bolt and therefore be much safer.
During 2015-2016 Rock Solution North started extended patent protection and to verify the technology in laboratories and in mines. The first test with EXI-bolt prototypes was performed in real production in autumn 2016.
EXI-bolt is a mechanically anchored dynamic rock bolt with superior features:
- Fastest bolt to mount
- Can be mounted by standard rock bolt equipment or manually
- Full strength immediately
- Highest energy absorption, more than 70 kJ
- Can be elongated more than 400 mm before breaking
- Shows the load on the bolt
- Shows if the bolt is broken
- Fully recyclable
