Add blocks and increase target
In this section, we will proceed with the scenario developed in the previous step. Ensure that this scenario is currently active in MineTwin before moving forward.
We will now focus on adding more blocks, i.e. places from which we extract the ore.
1. Make sure everything is ok with a single block
Let us simulate our scenario till the end and check the end state of our simulation model. Below is how the MineTwin window will look after finishing the simulation experiment:
You might need to zoom out of the Production Cumulative Total, t chart in the top right corner to replicate the screenshot above. You can do this by clicking on the chart and scrolling with your mouse.
On the Simulation status view, we can see that 365 days of the mining operations have been simulated:
On the Animation view, we can also see that our block has been emptied:
Indeed, on the Production cumulative total view, we see that we were meeting our target up until mid May. When the production line went flat:
Note: You can click on any chart to show a vertical line with the date, and then all the legend items will show the exact value at the specific point in time
So, we have made sure our only block is mined till its end in our scenario.
2. Specify other block locations
Let us now go back to Editor mode and create several blocks using the block palette tool. We also have to make sure the direction of the blocks makes sense. In this case, it does not, so we use the Reverse button in the upper part of the Map view to correct the direction.
Now, let us review the blocks we have just created in the blocks table view:
Now we have created our blocks and corresponding mine segments, but we have not defined any properties for these blocks (i.e. material mix, mining method, etc.). We can now click the Check button and see how MineTwin points us to these multiple missing properties:
MineTwin provides a block properties copying tool similar to the "Format painter" tool of Microsoft Office applications. To do this, you can right-click on the block with the properties you want to copy and select Create block pattern from the context menu. You can then select the new block where you want to paste the first block’s characteristics by right-clicking and selecting Apply block pattern from the context menus.
On Windows, the block copying tool can be activated by clicking the block pattern button in the upper part of the blocks table view. Let us now activate this tool and apply the properties of our first block to all other blocks by Ctrl-clicking the lines in the blocks table.
We can now click the Check button once again to make sure all the errors are gone.
If we now go to the simulation mode and run our scenario again, we will see that we are perfectly meeting our target:
3. Adjust simulation period and production target
Let us now go back to the Editor mode using the mode drop down:
Let’s do the final adjustments before going into the scenario analysis mode.
Firstly, let us shorten the simulated period to just 3 months by adjusting the end date of both our target and scenario accordingly, thus increasing the production target to 100Kt per 3 months (400Kt per annum):
Let us now save the scenario and rerun the simulation. Note how we are still meeting our target plan in our 90-days scenario:
Here is the scenario that must be the result of this training.
