Hi All,
I am wondering does somebody survey the production longholes. Not only the collar position but the whole track of the hole/
In our case we are using stoping method. And we have production holes about 30m long. And in the practice after blasting a lot of issues are coming up like overbreak and underbreak plus some "bridges" lefts in the stope.
So we decided to track the drillholes inside. We are using a Ranger Survey Tool and we have some interesting results. But it is a little hart to push the instrument 30m up, so I want to find an easier way to do this.
Is somebody use some different method or instrument?
