A guidance system for mining a seam of material includes a mining machine, a carriage, and a guide assembly. The mining machine includes a cutter head and defines a roll axis, a pitch axis, and a yaw axis. The carriage includes a first emitter, a second emitter, and a third emitter. The first emitter projects a first laser that is aligned with a seam plane. The second emitter projects a second laser, and the third emitter projects a third laser. The guide assembly includes a first indicator and a target. The first indicator is aligned with the second laser, and the target is aligned with the third laser. The relative positions of the first indicator with respect to the second laser and the target with respect to the third laser indicate the orientation of the roll axis, pitch axis, and yaw axis relative to the seam plane.
