Design

Use the Design group to setup Open Pit Mine Design Parameters.

Default Slope Restrictions

Use the Slope Restrictions dialog to define bearing and slope angle definitions for each pit slope region. Используйте кнопки на локальной панели инструментов для Управлять строками в списке.

The Lerchs–Grossmann algorithm can make use of variable slope angles in order to derive a truly optimal pit. Small changes in slope angle within each region can change the amount of waste to be removed, and have a significant effect on the degree of selectivity in mining operations.

It is often desirable to change slope angles for geotechnical reasons, or to allow for changes in rock type.

Bearing

The direction in degrees (0 to 359.99), clockwise, from the positive Y direction.

Slope Angle

The overall pit slope in degrees (0.01 to 89.99) from the horizontal.
