Define Hole Tables Dialog Defining and building dynamic drillholes from individual drillhole tables

To access this dialog:

• Activate the Sample Analysis ribbon and select Prepare Samples | Define Holes

The Define Hole Tables dialog is used to map the loaded drillhole files to the standard drillhole tables and their fields, used to create dynamic or static drillholes from

As Drillhole data files are imported into the project document, the new tables are automatically added to the hole tables definition, and, when sufficient survey data has been identified, the drillholes are desurveyed. So whether you build the holes using the Data Load Wizard or load and define each table individually using this dialog, by the time all the tables have been imported the program will also have completed defining and building the drillholes.

Files can only be accessed using this dialog if they have been previously loaded into memory. For more information on loading files, see Loading Data. and Loading Dynamic Drillhole Data. You can view and change the default drillhole definitions and rebuild the holes at any time using the commands in this dialog.

 

Field Details:

The following fields are available:

Collars: select the table containing hole collar data.

Surveys: select the table containing downhole survey data.

Traces: optional; select the table containing hole trace data. If traces are desurveyed by the program, this table is created and assigned by the program.

Assays: optional; select the table containing sample assay data.

Lithology: select the table containing sample lithology data.

Intersections: optional; select the table containing drillhole intersection data. This may be an imported table, or created by the program.

Interval Logs: select the table containing hole interval data, e.g. rock mass rating data

Depth Logs: select the table containing hole depth data e.g. downhole geophysical survey data

Tables can only be accessed using this dialog if they have been previously loaded into memory. For more information on loading files, see Loading Data. and Loading Dynamic Drillhole Data.

 

Table Properties: display and edit field assignments for the selected table using the Define Drillhole Data Table dialog. Note that this dialog is displayed automatically when a new table is selected from any of the drop-downs.

Rebuild...: desurvey traces using the Build Holes dialog, after making changes to the hole definition.

Desurvey Method...: select a desurveying method using the Desurvey Method dialog.

Import Table...: import an external data file using the appropriate Data Source Drivers via the Data Import dialog.

Create Table...: create a new empty table. Displays the Select Table Type dialog.

 

The mapping of data (required fields for defining a drillhole to fields contained in a database table) simply 'links' external and required data. When the process is run, all fields in the selected table will be used to create the drillhole object(s), regardless of whether they are mapped (assigned to drillhole data fields) or not.
