General

Name

Type a base name for new drill plans as you want them to appear in the Create Manual Drill Plan command, Project Explorer, and in DPS900. This name can be edited when you create Manual drill plans.

Default layer for holes

Specify the layer to use when adding drill holes to a drill plan. This layer can be edited when you create manual drill plans.

Specify the hole length (from start point to end point) to use when initially creating either blast or split drill holes for a Manual drill plan.

1. Rock surface
2. Design surface
3. Split hole
4. Blast holes - The split hole and blast hole use the same default length.
5. Display length - Make the default length long enough to extend above the highest point on the rock surface (or longer if there is an existing ground surface above the rock) for both perpendicular and inclined drill holes. This enables the DPS drilling machines to navigate to each hole.
6. Subdrilling - The default length does not need to include a subdrilling depth below the design surface.

Specify the shortest total length (from rock point to subdrilling point) that all holes must be.

Specify the maximum distance that a drill hole’s design point can be above the rock surface. Drill holes are not created where their design points would be farther above the rock surface than this tolerance.

1. Rock surface
2. Design surface
3. Maximum distance above rock tolerance
4. Drill hole will be created
   (design point is within tolerance)
5. Drill hole will not be created
   (design point is not within tolerance)

Note: Because design points should not typically lie above a rock surface, these drill holes are only created to account to potential inaccuracies in the rock surface model; it is better to create a planned drill hole where it may not actually be needed than vice versa.

(Corridor drill plan only)

...treat the outermost template instructions as ties - If none of the corridor instructions are a Side slope type, check this box to have them act as tie segments to the rock surface anyway. See Create a Corridor Drill Plan for details.

Blast Holes

(Corridor drill plan only)

Uncheck this box to prevent the creation of blast holes along with the split holes.

Specify the cylindrical diameter of drill holes (in inches or millimeters based on your project units). This diameter is shown in graphic views.

(Corridor or Reference Line drill plan only)

• Forward – Select this to orient blast holes toward the alignment/reference line.
• Backward – Select this to orient blast holes away from the alignment/reference.

(Boundary, Grid, or Manual drill plan only) Specify the azimuth of drill holes (in the Plan View). The zero direction is north. Positive angles are measured clockwise from 0 to <360 degrees.

Specify the vertical angle of drill holes. The zero angle is straight down (nadir). Inclination should typically be between 0 and 45°.

Note: In a Manual drill plan, you can vary the orientation and inclination for each drill hole you add, but any single drill hole cannot have more than one inclination (variable inclination).

Specify a 3D distance within which duplicate hole design points will not be created; two blast hole or split hole design points cannot be this close to each other.

(Corridor drill plan only)

Select an option for spacing the blast holes:

• Station spacing and hole spacing – Select this to specify row/station spacing, maximum hole spacing, and extra hole edge tolerance below.
• Station spacing and spacing factor – Select this to specify a factor to apply to station spacing (instead of a maximum hole spacing) below. When you specify the Spacing factor, the Maximum hole spacing is calculated.
• Hole spacing and spacing factor – Select this to specify a factor to apply to maximum hole spacing (instead of a row/station spacing) below. When you specify the Spacing factor, the Row/station spacing is calculated.

(Grid and boundary drill plan only)

Click the Staggered box to offset every alternate blast hole along the row by 50% of the row spacing. The blast hole columns will follow the column spacing. Staggering begins forwards and backwards from the grid origin.

1. grid origin
2. 50% of row spacing

Note: This setting is not available when Drill Plan Type is set to Boundary and Grid type is set to Row-based (variable hole spacing).

In the Method list, select how you want tospecify the distance along the alignment (station) between rows (cross-sections), from the start station to the end station.

• Factor of burden - Select this to specify a "factor of diameter", which is used with the Hole diameter to calculate the burden. This factor is usually determined by the kind of explosive used. In the factor of diameter list, select a type:

  32 (ANFO)
  38 (Emulsion)
  40 (Dynamite)
  Custom - Enter a factor in the box.

Note: When the burden is defined by this factor, it is still compatible with the factor of burden subdrilling setting, and the alternative hole spacing method for corridors (max spacing along rows is determined by a factor of the burden).

• Distance - Select this to specify the tolerance as an absolute distance. Then enter the distance in the Distance box.

Column/Maximum hole spacing

(Boundary or Corridor drill plan only)

• For a Boundary drill plan:
• If you selected Grid (fixed hole spacing) as the Grid type in the command, specify the distance between holes in a row (column spacing).
• If you selected Row-based (variable) as the Grid type, specify the maximum distance between holes within a row in the grid.

For a Corridor drill plan, specify the maximum distance between holes in a row.

Depending on which Spacing factor you selected above, specify a factor to apply to the row or station spacing of drill holes.

(Boundary or Corridor drill plan only)

For a Boundary drill plan, specify a planimetric distance from the boundary within which blast holes will not be created.

For a Corridor drill plan, specify a distance from the rock surface’s intersection with the split hole line within which blast holes will not be created.

(Reference Line drill plan only)

Specify a distance to a line segment’s end point within which a split hole will be snapped to that end point’s location.

Subdrilling

Check the box to extend drill hole lengths by a percentage of the hole length (to achieve a subdrilling depth, usually beyond the design surface). This is only applied if a rock surface is specified for the drill plan.

(not in Manual drill plans)

Check the box to extend drill hole lengths by a percentage of the hole length (to achieve a subdrilling depth, usually beyond the design surface). This is only applied if a rock surface is specified for the drill plan. Then specify the factor of the hole length to add.

(Method is not in Manual drill plans)

In the Method list, select how you want tospecify the maximum distance between a planned blast hole's design point (coordinate) and its associated as-drilled blast hole's design point (coordinate). This affects whether an as-drilled hole is considered passable in the Drill Hole Quality Report.

• Factor of burden - Select this to specify a "factor of diameter", which is applied to the previous Diameter tolerance to calculate the burden. Then enter the factor in the Factor of burden box.
• Distance - Select this to specify the tolerance as an absolute 3D distance. Then enter the distance in the 3D distance box.

(not in Grid drill plans) Specify the maximum 3D distance between a planned split hole's design point coordinate and its associated as-drilled split hole's design point coordinate that is allowed for the as-drilled hole to be considered passable in the Drill Hole Quality Report.

Estimation

Estimate the average rate at which split holes and blast holes can be drilled in your project's distance units per hour.

Estimate the cost to your company to drill either split or blast holes for an hour.

Note: For drill planning cost estimates, this program displays the currency symbol and format that you have set in Microsoft Windows^® Regional and Language Options. The units and calculations, however, are not associated with a specific currency, so if a project is opened on a computer with different regional settings, those currency symbol and formats are used, but no conversion between currencies has been made.

Apply a positive factor to the drilling cost per hour to account for any real-world variables that might negatively affect the drilling cost per hour.
