Bore Holes Logging in n4ce
n4ce has the ability to store and manipulate multiple models, but it is with Bore Holes that this is more fully explored. The first stage is to create data that can be imported into n4ce. In most cases we would recommend Microsoft?s Excel Spreadsheet program, to create a comma delimited (CSV) file, but any suitable ASCII (Notepad) editor would suffice. A typical listing is shown below.
Name,Bearing,Incline,X,Y,Z,RH,SS1,CO1,MS1,SS2,CO2,MS2
BH01,0,0,320.000,100.000,33.500,5.0,3.0,1.0,2.0,2.0,1.0,2.0
BH02,0,0,320.000,120.000,33.300,5.0,3.0,1.0,2.0,2.0,1.0,2.0
BH03,0,0,320.000,140.000,33.200,5.0,3.0,1.0,2.0,2.0,1.0,2.0
BH04,0,0,320.000,160.000,33.400,5.0,3.0,1.0,2.0,2.0,1.0,2.0
BH05,0,0,320.000,180.000,33.700,5.0,3.0,1.0,2.0,2.0,1.0,2.0
The first line contains a header identifying the name of each bore hole followed by its direction in terms of Bearing and Inclination (not implemented yet). The ground coordinates of the borehole then follow this and the codes used to identify each surface the boreholes pass through. In the above example RH (Rock Head), SS (Sand Stone), CO (Coal), MS (Mud Stone), are typical examples.
The CSV file is loaded into n4ce by right clicking over the Model and selecting New as shown above. From the Bore Hole option, you will be expected to select a suitable CSV file.

n4ce will create multiple models based on the data provided. These will be identified with names corresponding to those provided in the heading. Levels in each model will be determined from the Ground Level (GL) and depths, as provided.
Models are triangulated and added to the list of Associates to the Ground Level Model. These can be seen when selecting the Associates option from the DTM menu. |
|
Once you have created the Borehole Models, they can be used like any other model for Volume and Section calculations.
When you use the Query Borehole option in the Design menu, from the GL Model, this looks at all the Associated Models and identifies points below the GL Point selected. |
|
| New Borehole positions can be created on the GL Model. Firstly, Insert points into the GL Model, using DTM Interpolation to determine the heights from the GL Model. A Create Borehole option can then be used to form points on all the Associated Models.
You will now be able to plot Borehole Tables/Charts at these new points, as shown below.
|
Before plotting the Borehole Chart, defaults need to be recorded. You will be expected to enter each surface name in turn, with a Hatch Style and Pen Colour. The Description is used to identify each surface.
You will then be asked select the Borehole you wish to plot. You will then be invited to plot the chart, which appears attached to your mouse cursor, like plotting sections.
