A spray system for dust control on a shearer machine that operates laterally with respect to a mining floor surface is provided where the spray system is provided with a set of first ranging arm sprays mounted on a first ranging arm and wherein said first ranging arm is located on a first end of a shearer machine chassis. A set of second ranging arm sprays is optionally provided and is mounted on the upper side of the first ranging arm and resides approximate to and in operational relationship to the set of first ranging arm sprays. Furthermore, a plurality of chassis spray sets may also be optionally provided and are located on a mining side of said shearer machine chassis and reside in a non-linear format. Moreover, a set of shearer-clearer venturi arm sprays may also optionally be provided and is mounted on a shearer-clearer venturi arm that resides as an angular extension of the set of first shearer-clearer arm sprays.

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.
