Abstract
In practice, many geological controls in automatic or semi-automatic estimation and modelling are essentially geometrical controls. The presents two techniques for geological/geometrical control. Both techniques are types of estimators and/or interpolators of shapes. The first is a method for fitting spline surfaces to control orebody boundary estimation and unroll orebodies. The second is an application of Minkowski addition to interpolate shapes such as orebody outlines or stope boundaries and to control estimations.
