Design and research of comprehensive testing device for coal and gas outburst alarm and power failure

This paper designs a comprehensive testing device and method for coal and gas outburst alarm and power-off, which can realize the accurate, efficient and automatic testing of coal and gas outburst alarm and power-off locking function of heading face, coal and gas outburst alarm and power-off locking function of coal mining face of coal mine safety monitoring system. In addition, it can also realize the wind power and gas locking function and power-off time, substation over limit locking function and power-off time accurate test of substation fault locking function and power-off time.
