Coal mine six systems, coal mining system, driving system, mechanical and electrical system, transportation system, ventilation system, drainage system, referred to as “mining machine transportation” + drainage system. In addition, China will establish and improve six underground safety avoidance systems in coal mines nationwide, including monitoring and monitoring, personnel positioning, emergency avoidance, pressure wind self rescue, water supply rescue and communication.
Six system standards, monitoring and monitoring, personnel positioning, communication and liaison, emergency avoidance, pressure wind self rescue, water supply rescue.
According to the conditions of underground workers and roadway section, combined with the mine disaster avoidance route, the mine should reasonably select and arrange the refuge chamber or mobile rescue cabin. Fixed refuge chambers shall be set at the bottom yard of each horizontal well in all mines.
Composition of compressed air self rescue system: air compressor, air supply pipeline, valve, steam water separator, compressed air self rescue device (including pressure reduction, throttling, noise elimination, filtering, switch and other components as well as protective bag or mask)
