10 Automation Definition Using self-operating equipment to reduce human exposure to the mining environment and routine or repetitive work. - Atlas Copco Terminology: Manual Operation A piece of equipment being operated by a person in the cab. Radio Remote Control (RRC) A piece of equipment being physically operated by a person through a Line Of Sight (LOS) or Video-Remote equipment. Tele-Remote Control A piece of equipment being physically operated by a person at an operator station which is not necessarily located near the equipments' working area. Autonomous Operation A piece of equipment under self control with the possibility of human supervision and override. 10
