How to Calculate Grade Tonnage for Third Party Block without Wireframes on Geology Modeler Module of Micromine Origin – Origin & Beyond Quick Articles

Sometimes all you received from a client could be a block model file or even legacy files created in another software. Furthermore, your functionality could be limited to wireframing based on which Micromine module you may have. And, if maybe you do not have the Resource Modeler module which allows you to deal with block models more comprehensively. You can easily import the block model file into Micromine and still get a good grade tonnage report from the wireframe tool. I will quickly take you through the steps on how you can get it done.

Import the block model

The file tool is used to import data into Micromine. You select the File ribbon and under the Import group click on the down-arrow below Import. Along the drop down menu, select Block Model.

The Import Block Model Files form will pop-up. Select the Format you want to import from as shown on the image below. Populate the form accordingly and ensure you select Autoload. You can then go ahead and view the block model data in whichever manner you prefer.

Creating a Shell/Wireframe

The challenge comes when you have to produce a report such as Grade Tonnage report. If you are on a Resource Modeler then it is quite straight forward with the Block Model Report under Block Model ribbon. But if you do not you may resort to the wireframe tool.

Click on the Wireframe ribbon, and go to Report group and click on Grade Tonnage (Block Model). This allows you to calculate wireframe grade tonnage using a block model. Remember that you may have only received the block model without wireframes. So this tool becomes challenging to use.

Generate a Shell/Wireframe

So, we need to generate a wireframe for this block model using the Generate Shell. So still under the Wireframe ribbon, click on down arrow under Generate Shell to select the Block Model (Outer Shell). This tool will creating and encompassing wireframe around the block model to create a volume wireframe.

Populate the Generate Block Model Outer Shell as seen below and click Run:

However, you may want to calculate the tonnage according to a specific cut-off grade. In that case you can create grade shells according to cut-offs. You select the second option which allows you to Generate Block Model Grade Shells for your defined cut-offs as shown below:

You also have a choice of creating a shell using block model centers in the third option, however the first two options will suffice for the purposes of this task. Remember to save the wireframes in the Vizex Layer Display.

Creating Grade Tonnage Report

Then the wireframe tool can be used to calculate the Grade Tonnage report. Under the Report group select the Grade Tonnage (Block Model) option. Under input Select Wireframe choose Set and right click in the space next to Name. Select new and the give the form that comes up a Name then click OK. A form Manage Wireframe will pop-up. Select the Type and use Name under Select By and then select accordingly the wireframes.
