Comprehensive prevention stope " one through three prevention " accident equipment; It is dark to it is characterized in that 0.2 meter of rib is stretched in heavy supporting, and the heavy air door doorframe between the heavy supporting and the connecting mode of heavy supporting are steel plate, link through screw; Steel heavy air door door leaf and doorframe match; Heavy air door doorframe and door leaf are for being hinged, and door leaf and hydraulic press are closed door leaf through drive link, and sensor is through the operation of relay control hydraulic press.
Comprehensive prevention stope " one through three prevention " accident equipment; It is characterized in that leaving belt conveyer and drag conveyor import and export on the steel heavy air door that stope installs; Propelling along with stope; Comprehensive prevention stope " one through three prevention " accident equipment is every at a distance from 50 meters, moves forward once.
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 be with the moving of stope, and can be repeatedly used.
3, can various accidents be controlled 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 has simple in structurely, and overall dimension is compact, and fault is few, and self-security is high, and can take precautions against natural calamities, can combat a natural disaster, but the also disaster relief.
