Abstract

Full-automatic safety equipment for a driving working face laneway is installed in the inward range of six meters from a return air roadway opening of the driving working face roadway and is used for guarding against fire, inundation, coal and gas outburst accidents on a driving working face. The full-automatic safety equipment for the driving working face laneway is characterized in that heavy supports and a roadway wall are firmly fixed into a whole, a steel heavy air door is installed between the heavy supports of the wall of the roadway wall and is controlled through a hydraulic machine, and the hydraulic machine is controlled through a pressure sensor. When the coal and gas outburst accident happens on the driving working face, pressure of gas has an effect on the pressure sensor, the pressure sensor controls the hydraulic machine, and then the steel heavy air door is closed through the hydraulic machine rapidly.

Description

Tunneling working face well tunnel full-automatic safety device

Technical field: tunneling working face well tunnel full-automatic safety device 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.

Tunneling working face well tunnel full-automatic safety device, the return airway road junction that is installed in the driving face tunnel is inward in 6 meters the scope, in order to prevent the driving face fire, floods, the accident such as coal and Gas Outburst, it is characterized in that being integrated by fixedly securing between heavy supporting and the roadway wall, the steel heavy air door is installed between the heavy supporting of roadway wall, the steel heavy air door is controlled by hydraulic press, hydraulic press is controlled by pressure sensor, when driving face generation coal and gas burst accident, gas pressure is applied on the pressure sensor, pressure sensor control hydraulic press cuts out the steel heavy air door rapidly by hydraulic press.

Tunneling working face well tunnel full-automatic safety device all adopts dual power supply and batteries power supply, when the down-hole since accidental cause have a power failure, the batteries power supply is from trend tunneling working face well tunnel full-automatic safety device power supply, when the down-hole restores electricity, and the automatic disconnection of batteries power supply.

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.

Description of drawings:

Fig. 1: tunneling working face well tunnel full-automatic safety device schematic diagram.

1, heavy supporting; 2, roadway wall; 3, hydraulic press;

4, heavy air door; 5, pressure sensor.

The specific embodiment: now illustrate to the drawings as examples: tunneling working face well tunnel full-automatic safety device, be installed in driving face return airway road junction inward in 6 meters the scope, in order to prevent the driving face fire, floods, the accident such as coal and Gas Outburst, it is characterized in that being integrated by fixedly securing between heavy supporting (1) and the roadway wall (2), steel heavy air door (4) is installed between the heavy supporting (1) of roadway wall (2), steel heavy air door (4) is subjected to hydraulic press (3) control, hydraulic press (3) is controlled by pressure sensor (5), when driving face generation coal and gas burst accident, gas pressure is applied on the pressure sensor (5), pressure sensor (5) control hydraulic press (3) cuts out steel heavy air door (4) rapidly by hydraulic press (3).

The place that first tunneling working face well tunnel full-automatic safety device will be installed is cleared up, tunneling working face well tunnel full-automatic safety device is installed in access adit to be no more than in 6 meters the scope with inner, 0.2 meter of slotting is dark in the coal seam, heavy supporting (1) is extend in the slotting of coal seam with inner 0.2 meter, realize that heavy supporting (1) and roadway wall (2) fixedly secure, the heavy air door (4) of all steel material open inward is installed in heavy supporting (1) again, to resist various disasters, install and debug, confirm errorless rear unlatching air door, make air door be in normally open, namely realize installing and using of tunneling working face well tunnel full-automatic safety device.
