Abstract: Combined with AQ 6201-2006 Coal Mine Safety Monitoring System of General Technical Requirements and MT/T1079-2008 Mine Power Controller,we analyze the functions of the mine safety monitoring system, and research and design the mine power-off control system. According to various types of feed transducer for mine, we design a new mine power-off controller. This power-off controller which includes power-off control circuit and electric powersupply circuit can meet the requirements of the above-mentioned two standards, and it will have great practical value and guiding significance.
