Technical field: comprehensive prevention driving face " one through three prevention " accident equipment belongs to a kind of safety equipment of installing in the coal mine down-hole tunnel, is specially adapted under the coal mine each access adit and installs and uses.
Background technology: by prevent the equipment of various natural calamities a lot of under the retrieval coal mine both at home and abroad comprehensively, but can be used in the equipment of Automatic Control fire, floods, coal and Gas Outburst, all do not find both at home and abroad, the down-hole catches fire and mainly uses the fire dam fire sealing at present, it also mainly is shutoff that floods occur, and the measure means are a lot of when coal and Gas Outburst occur, can't be with disaster control within the specific limits but also exist, fire often occurring enlarges, floods flood whole mine, and Gas Outburst causes that significant explosion causes well to ruin the serious accidents such as the people dies.
Summary of the invention: the objective of the invention is the problem for above-mentioned existence, by domestic and international visiting and learning and three more than ten years the coal mining accident management experience and test of many times invented this technology.
Comprehensive prevention driving face " one through three prevention " accident equipment, be installed in the return aircourse of driving face, within the scope of work plane 30-50 rice, be used for prevention driving face fire, floods, the accident such as coal and Gas Outburst, it is characterized in that: be integrated by fixedly securing between heavy supporting and the roadway wall, fixedly secured by anchor shaft anchor cable between heavy supporting and the roadway wall and be integrated, two cover steel heavy air doors are installed in the front and back in the heavy supported laneway of roadway wall, and firmly be connected as one with heavy supporting, on the steel heavy air door escape hatch is installed, the opening direction of escape hatch is opposite with the opening direction of steel heavy air door, front and back two cover steel heavy air doors are controlled by hydraulic press, hydraulic press is by pressure sensor or high-temperature flue gas sensor or liquid level sensor control, when driving face generation coal and Gas Outburst, and when producing pressure and being applied on the pressure sensor, pressure sensor control hydraulic press cuts out the steel heavy air door rapidly by hydraulic press; When the driving face breaking out of fire, high temperature or flue gas make high-temperature flue gas sensor control hydraulic press, rapidly the steel heavy air door are closed by hydraulic press; When driving face generation floods, liquid level sensor control hydraulic press cuts out the steel heavy air door rapidly by hydraulic press; Thereby the gas accident that driving face is occured, fire incident, floods accident control be at minimum zone, and process.
Comprehensive prevention driving face " one through three prevention " accident equipment, it is characterized in that the steel heavy air door top that driving face is installed is left the import of booster air duct and peep hole, taken out, water filling (gas) hole, along with driving face is pushed ahead, two cover steel heavy air doors every 30-50 rice to reach once.
Tunneling working face well tunnel full-automatic safety device compared with prior art has the following advantages:
1, tunneling working face well tunnel full-automatic safety device 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 driving face, and can be repeatedly used.
3, can be with various accident controls at the roadway mouth with inner, avoid fault spread to 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 tunneling working face well tunnel full-automatic safety device can with the underground monitoring Monitor-Networking, and be transferred to ground and carry out Artificial Control and open.
7, tunneling working face well tunnel full-automatic safety device 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.
