<p num="1"><br/><br/><br/>A mining apparatus includes a miner, a conveyor unit and a steering unit <br/>connecting the miner and conveyor unit. The apparatus also includes a heading <br/>sensor and a controller responsive to the heading sensor. A first actuator is <br/>carried on the miner, the control unit or the steering unit. The first <br/>actuator is positioned to a first side of a midline of the miner. Further a <br/>second actuator is carried on one of the miner, the conveyor unit and the <br/>steering unit. The second actuator is positioned to a second opposite side of <br/>the midline of the miner. The first and second actuators are utilized to <br/>adjust a connection angle between the miner and the conveyor unit either side <br/>of parallel in order to maintain the miner on the desired directional heading.<br/>
