There are some tools in MP3D that greatly simplify users' work when it comes to designing piles, pits and accesses.

In this edition of Dicas & Tricks, we will present four of them: Dump/Spoil to Target, Surface Reslope, Attach Template along Polyline and Pit Expansion. These tools can also be used for environmental applications. An article on this subject can be found here.

Dump/Spoil to Target

With this tool, present in the OP Eng Tools menu, it is possible to quickly design pile solids, having only a polygon, inclination angle, tolerance, pile volume and topography as input data.

The tool Dump/Spoil to Target it is interactive with the user and warns them, in the MineSight Message Window, if their goals are not achievable, then suggesting acceptable values for the project.

Surface Reslope

This tool, also present in the OP Eng Tools menu, is used to smooth the angles of a surface based on a user-specified value to efficiently balance cut and fill.

The images below demonstrate the result of applying Surface Reslope.

Attach Template along Polyline

This tool, present in the menu Surface => Create, creates surfaces based on some existing models or models created by the user, applying them along a line.

Some of these templates, applied to a transport profile, automatically create accessways and projections for cut and fill.

With this option, it is also possible to create underground accesses, shafts, among others.

pit expansion

This well-known tool is widely used for pit operation, but can also be used for access and road design.

Contrary to common sense, base pit lines do not need to be polygons. As can be seen in the image below, any line, as long as it is 2D and assigned as a base pit, is operationalized by pit expansion.

The same pit expansion, with the function Slot, it is possible to operate access in a simple and intuitive way. To do this, all you need is a baseline (base pit), the trajectory line and geotechnical parameters of the access, which can also be read directly from the block model.

Design of piles, accesses with operationalized slope, operationalized pits or embankments: work that requires a lot of time to do, but that can be simplified with the use of tools MinePlan, presented in this Tips & Tricks.

To the next!
