In today's Tips & Tricks, we are going to introduce a very practical tool, the Drillhole Design Tool. This tool is used to create drillholes with deviations in a simple and accurate way, based on the directional and geological specifications of the project, increasing the accuracy when carrying out the drilling planning.

O drillhole Design is accessed from the Geo Tools menu in MS3D. With this tool it is easy to create boreholes with deviations in order to reach the desired geological structures. For this purpose, drillholes can be designed using one of the three available projection modes: “Constrained design”, “Direct design” and “Use existing polylines”.

In “Direct design” mode, drill holes are calculated from parameters such as coordinate, azimuth and dip at the hole mouth. It is also possible to determine the deviation of the hole based on the physical characteristics of the rock mass and the rod to be used, such as layer dip, percentage of solid rock and rod size. Such deviation determination is a great differential when planning the drilling because it reflects more real results.

The “Constrained design” option automatically calculates the hole that connects the collar to the target, within a tolerance specified by the user, the tolerance can be applied to the collar or to the target to be hit. In this mode, the mouth of the hole and the target must be provided, typing the coordinate in the available fields or selecting it directly in the viewer. In addition to these determinations, it is also possible to determine the deviation of the hole based on the physical characteristics of the rock mass and the rod to be used.

For the “Use existing polylines” option, just select the polyline that represents the hole directly in the viewer.

The generated holes can be stored both in object format and in an MSTorque database. For more convenience and accuracy, be sure to use the Drillhole Design Tool for creating offset drill holes.
