Move mast

Choose Move Mast from the RING DESIGN menu to display the MOVE MAST menu. If no drive has been selected, the Move Mast function allows you to select a drive and stope outline by displaying the prompt:

Indicate the Survey Openings

Select a segment from the openings as the current opening to display the prompt:

Indicate the Stope Outlines

Select a segment from the stopes to use as the current stope. Choose Cancel to display the HOLE LENGTH form to allow drilling of fixed length holes without use of a stope outline.

The method used to find the floor of the survey opening is as follows:

  • Find the point with the lowest Y value
  • Move to the left of this point until X values begin increasing (this is the left extent of the floor)
  • Move to the right of the minimum Y point until X values start decreasing (this is the right extent of the floor)

Note that this method will not handle fold backs or vertical points on the floor. If you have fold backs you will have to clean up the data.

Hole length

Enter the length of the holes to be drilled and choose Apply to design fixed length holes without using a stope outline, or Cancel to re-select the current opening.

Note:Only the offset and angular toe spacing algorithms can be used in stope-less design. The offset method uses the end of the previous hole instead of the intersection of this hole with the stope to calculate the position of each hole. See DRILLING Parameters for explanation of these toe spacing methods.

After selection of a stope outline, or choosing Apply on the HOLE LENGTH form, a diagram representing the drill mast and carousel will be placed in the selected drive outline. See Edit Rig for information on defining mast and carousel dimensions.

If the carousel crosses the drive outline in this initial position, the message:

The New Rig position would be located outside the Survey Opening

will be displayed in the message window and the prompt:

Select and rotate the drill mast is displayed on the function line, allowing you to rotate the mast to an orientation which allows the mast to fit inside the drive outline. Press (ESC) if you do not want to change the orientation of the mast.

After the mast has been rotated, the prompt: Select and drag the drill mast is displayed on the function line, allowing you to move the mast to a position which allows the mast to fit inside the drive outline. Press (ESC) if you do not want to move the mast. If the mast fits entirely inside the drive, the screen will be rescaled to show the selected drive and/or opening, otherwise you will be prompted to reselect the current survey opening.

The New Rig position would be located 
outside the Survey Opening

The selected opening (drive) is either not wide enough or not high enough to accommodate the currently selected rig and carousel. Check the rig definition by using RIG Edit from the DRILLING menu.

The specified hole length is greater than the maximum hole length of the rig.

The hole length entered on the HOLE LENGTH form was greater than the maximum hole length specified for the current rig. Check the rig definition by using RIG Edit on the DRILLING menu, or enter a smaller hole length.

The selected drive segment is not valid as it is open.

The segment selected as the current drive outline was open. A segment must be closed to be a valid section through an opening. Select a different segment at the Indicate the Survey Openings prompt or choose Edit Openings from the RING DESIGN menu and use Segment Close to close the segment.

The New Rig position would be located outside the Survey Opening

The mast cannot be positioned entirely inside the survey opening. Check the rig definition by using RIG Edit on the DRILLING menu.

The new rig position would place the pivot point outside the reach of the rig

The mast cannot be moved to the specified coordinates as the pivot would be below the minimum height, above the maximum height or outside the lateral limits specified for the rig. Check the rig definition by using RIG Edit on the DRILLING menu.

The MOVE MAST functions allow movement of the mast in the plane X and Y directions within the currently selected drive outline, while maintaining the mast orientation. To move the mast to a new drive outline, select RIG New Position from the DRILLING menu.
