Hello, everyone.
This is Enta.
It's Sunday, but I'm still doing various community tasks here and there...
I say "work," but it's really just paperwork...
But that's beside the point.
Here are some tips for grouting self-drilling rock bolts.

Self-drilling inevitably involves the use of rock drill oil and grease on the coupler.
As a result, there is a possibility that areas may develop where the cement slurry does not adhere properly.
Additionally, due to the nature of the installation, spacers can only be attached to the head.
The grout doesn't spread easily.
To ensure the work is done as thoroughly as possible, it’s a small thing, but it’s a good idea to do what’s shown in the video.
The same applies to other types of perforations, but this is especially true for self-perforations.
See you later.
