Abstract
The invention discloses a device for comprehensively preventing one-ventilation and three-prevention accidents on a tunneling working plane. The device is installed in a return air tunnel of the tunneling working plane and within 30-50m from the working plane, and is used for preventing the tunneling working plane from accidents of fire disaster, flood, coal and gas outburst and the like. The device is characterized by being integrally fixed with walls of a roadway through a heavy support; the heavy support is solidly and integrally fixed with the walls of the roadway through an anchor rod anchor cable; two sets of steel-made heavy air doors are installed in front of and behind a heavy supported tunnel of the walls of the roadway and are solidly and integrally connected with the heavy support; emergency exits are installed on the steel-made heavy air doors; opening directions of the emergency exits are opposite to opening directions of the steel-made heavy air doors; the two sets of steel-made heavy air doors in a front and rear manner are controlled by a hydraulic machine; the hydraulic machine is controlled by a liquid level sensor; and when a flood accident happens to the tunneling working plane, the flood water level affects the liquid level sensor, the liquid level sensor controls the hydraulic machine, and the steel-made heavy air doors are quickly closed by the hydraulic machine.
Description
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 controlled by liquid level sensor, when driving face generation floods accident, the floods water level is applied on the liquid level sensor, and liquid level sensor control hydraulic press cuts out the steel heavy air door rapidly by hydraulic press.
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.
