Described herein is a computer-implemented method for illustrating work status for an area of interest of a mine worksite. The method comprises determining a dataset comprising recorded data representing an elevation map of a surface of the mine worksite for at least the area of interest. The elevation map is based on measured data for the surface. The data set also comprises reference data representing a reference elevation topography for at least the area of interest. The method further comprises generating model data, based on the determined dataset, defining a 3-dimensional model for illustrating, in an image portraying a 3-dimensional view of the model, divergence between the elevation map and the reference elevation topography.

A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.
