# Auto staking lines or points in Mines

To automatically stake out... | Select...
--- | ---
A line at set intervals along the mine back (ceiling). | Centerline
A line at set intervals along the mine walls. | Grade line
Intersection points between the mine walls and a line defined by two points. | Laser lines
Intersection points between the mine wall and laser lines defined at right angles relative to the centerline at a defined interval. | Laser lines offset from a centerline
The intersection point between a mine face and a line. | Project line
The intersection point between a mine face and a line defined by two points. | Blast holes
Pivot points that have been projected up onto the mine back. | Pivot points

To watch how to stake out different lines and points and how to configure options, take a look at the Trimble Access Mines playlist on the Trimble Access YouTube channel.

## Adding data to the job

You can add linework to the job from a DXF or STR (Surpac) file.

Points can be imported into the job, linked to the current job, or imported into another job and that job linked to the current job. To import points, tap and select Job and then tap Import. Depending on the features you want to stake, the points in the job must meet the following criteria:

- Pivot points must be identified by either a prefix or suffix in their point name.
- Laser line points must be matched pairs of points defined using their point names. A point must have a prefix or suffix to identify it as the left or the right hand end of the line. The remainder of the point name must be identical for a match pair to be found. For example, if the Left points prefix is L and the Right points prefix is R, then the following points would be identified as matched pairs: L1–R1, L15–R15, L101–R101, etc.
- Blast hole points must be matched pairs of points defined using their point names. A point must have a prefix or suffix to identify it as the blast hole collar or toe. The remainder of the point name must be identical for a match pair to be found. For example, if the collar points suffix is C and the toe points suffix is T, then the following points would be identified as matched pairs: 1C–1T, 15C–15T, A1C–A1T, etc.
