Comprehensive prevention stope " one through three prevention " accident equipment, it is characterized in that leaving belt conveyer on the steel heavy air door that stope installs and drag conveyor is imported and exported, propelling along with stope, comprehensive prevention stope " one through three prevention " accident equipment moves forward once every 50 meters.
Comprehensive prevention stope " one through three prevention " accident equipment compared with prior art has the following advantages:
1, stope roadway automatic safety equipment adopts the resistance to compression of high strength heavy type steel, antiknock, firm.
2, adopt combined type easy for installation, quick, can move with the movement of stope, and can be repeatedly used.
3, can be with the control of various accidents at the roadway mouth with the lining, avoid accident to enlarge and injure other place, down-hole.
4, be easy in time control the generation of various accidents, because hanging in advance of each sensor provides grace time for closing heavy air door.
5, realized " one through three prevention, the comprehensive regulation ", not only can ventilate, combat a natural disaster, take precautions against natural calamities, and realized the mine essential safe type.
6, the various sensors on the stope roadway automatic safety equipment can with underground monitoring monitoring networking, and be transferred to ground and carry out Artificial Control and open.
7, stope roadway automatic safety equipment have simple in structure, the overall dimension compactness, fault is few, the self-security height can be taken precautions against natural calamities, can be combated a natural disaster, but the also disaster relief.
