Surpac

As a Geologist, you may be asked to produce a contoured gram meter plot to outline areas of the ore body that have the greatest value or potential ore shoots. This plot can also highlight areas of wider stopes, that then require more ground support during mining. This plot can also highlight areas where more drilling is required to upgrade the resource/reserve.

This is the 3rd post in the series “plotting long sections”. The files created in the 1st article, from the functions “Database>Composite>by Geological Constraints” and “Database>extract>zone thickness and depth” are required for this process.

In this second part post we continue on with the plotting of the Puncture Plot, but we will use entities to display the drillhole ID, grade and true width and how to display a legend.

As an underground geologist, one of your job’s may be to create a long section puncture plot of the ore body drill-hole intercepts displaying the grade and true width.

This plot can then be used to help monitor the grades while mining, and to assist in the design of infill drilling programs to upgrade the resource-reserves.

PLOTTING TIPS 6 to 10.

We continue with the second part of the Blog covering detailing simple GEOVIA Surpac Plotting Tips that incorporate some commonly raised questions and queries and which we think are important to other users as well.

Here are some quick and simple GEOVIA Surpac Plotting Tips & Tricks that incorporate some commonly raised questions and queries and which we think are important to others as well. Let’s get started!

Mine Surveyors need to produce updated Emergency plans every 3 months and provide these plans to the Mines Department. This may require resizing existing plans which can be time consuming.

The Emergency Plans typically have a text file containing all symbols and text that the Surveyor overlays onto an updated string and stope outline file. For this particular example, the original text file plot with the associated symbols and text was used with A3 emergency plans. This text plot now needs to be used for the A0 Mines Department plans. To save time in reproducing all the plans with the text, we recommend setting up plotting macros.

Proper representation of a surveyed area within a sheet that contains all the necessary information remains of paramount importance for Surveyors. Hence the act of taking the plot of actual data is a significant requirement.

Occasionally, surveyors may need to take the plot of a grid point RL value, of a surveyed area, with X-Y grid lines over grid points to check the profile undulation against RL variation.

Surpac has the capability to take such a plot, containing all the required information, into the sheet through a File-based plotting method.

In this example, I illustrate how to take a plot with the grid line offset using the Surpac file-based plotting method. To achieve this, you first need to create an entity related to which information you would like to display within the plot file.

In the image below, I have two string files with grid points and a separate boundary line separately. I would like to plot the grid points with symbol & RL value with the boundary line.

In today’s post, I’ll be talking about how to use multiple viewports in Autoplot in GEOVIA Surpac to illustrate images of information related to one another. We are using Surpac 6.8 in this example.

This feature is suitable for geologists wanting to view grade on section, and for engineers looking at the mine development plan. The techniques outlined in the video tutorial below can be tailored to suit applications for geologists and engineers in both underground and open-pit environments.

Here is a video from the recent webinar on how to plot Oblique Sections using Planes.

A common question we often receive from users is regarding how to create plots with multiple drawing areas. Today I’ll go through how to create a plot with four drawing areas – one for plane view and three for sections, with the title block in the bottom left corner, using Autoplot functions.
