I was asked the other day – can you filter the model for the mined / unmined material in Leapfrog. This got me thinking – the answer is yes but doing it once and only once is a lot of work to get a single result. If we flag a model as mined/unmined today, then tomorrow the result is wrong as we have mined some more. So I asked myself “Is there a way to create a mined model that is easily updated?” There is! It has been a while since I did a ‘how to’ post so I figured this might be a good topic to cover.
In Leapfrog Geo the terminology of the geology modelling process and workflow can easily impose a straitjacket on your thinking – create a geology model using erosion, deposition and intrusion surfaces. What you are in fact creating is a domain model using cutting, covering and slicing surfaces. Remove the geology straitjacket and you will see the domaining process can be used for anything. In this case we can use the cutting (erosion) and covering (deposition) surfaces to cut in a mined/unmined model. Then we can evaluate this model against the drilling, geology models and resource models to flag out the mined material.
