Abstract

A full-automatic safety device for a driving working face of a roadway is arranged at the driving working face of an air return roadway port and is used for preventing and controlling the accidents of ventilation, dust resistance, gas resistance and fire resistance in the working face driving. The full-automatic safety device is characterized in that heavy supports are firmly fixed with all the walls of the roadway into a whole, a heavy steel ventilation door is arranged among the heavy supports of all the walls of the roadway, the heavy steel ventilation door is controlled by a hydraulic press which is controlled by a pressure sensor, a high-temperature fume sensor or a liquid level sensor, so that the gas accident, the fire accident and the flood disaster at the driving working face are controlled in the minimum ranges and are processed.

Description

Driving face roadway automatic safety equipment

Technical field: driving face roadway automatic safety equipment belongs to a kind of safety equipment of installing in the underworkings of colliery, is specially adapted under the coal mine each access adit and installs and uses.

Background technology: through 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 outstanding equipment of Automatic Control fire, floods, coal and gas, 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 take place; And take place coal with gas when outstanding the measure means a lot, but also exist and can't fire expansion often occur with disaster control within the specific limits; Floods flood whole mine, and gas is outstanding to cause that significant explosion causes well to ruin serious accidents such as the people dies.

Summary of the invention: the objective of the invention is the problem to above-mentioned existence, through 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.

Driving face roadway automatic safety equipment is installed in driving face return airway road junction, in order to the generation of prevention and control driving face " one through three prevention " accident; It is characterized in that being one by fixedly securing between heavy supporting and the roadway wall; The steel heavy air door is installed between the heavy supporting of roadway wall, and the steel heavy air door is controlled by hydraulic press, and hydraulic press is by pressure sensor or high-temperature flue gas sensor or liquid level sensor control; When driving face generation coal and gas outstanding; And when producing pressure and affacting 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 gas accident, fire incident, floods accident that driving face is taken place are controlled at minimum zone, and handle.

Driving face roadway automatic safety equipment all adopts the power supply of dual power supply and batteries; When the down-hole since accidental cause have a power failure; The batteries power supply is from the equipment power supply of trend driving face roadway automatic safety, when the down-hole restores electricity, and the automatic disconnection of batteries power supply.

Driving face roadway automatic safety equipment compared with prior art has the following advantages:

1, driving face 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 driving face, 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 driving face roadway automatic safety equipment can with underground monitoring monitoring networking, and be transferred to ground and carry out Artificial Control and open.

7, driving face 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.

Description of drawings:

1, heavy supporting; 2, roadway wall; 3, hydraulic press; 4, heavy air door;

5, pressure sensor; 6, high-temperature flue gas sensor; 7, liquid level sensor.

The specific embodiment: existing is the example explanation with the accompanying drawing: driving face roadway automatic safety equipment; Be installed in driving face return airway road junction; In order to the generation of prevention and control driving face " one through three prevention " accident, it is characterized in that being one that steel heavy air door (4) is installed between the heavy supporting (1) of roadway wall (2) by fixedly securing between heavy supporting (1) and the roadway wall (2); Steel heavy air door (4) receives hydraulic press (3) control; Hydraulic press (3) is by pressure sensor (5) or high-temperature flue gas sensor (6) or liquid level sensor (7) control, when driving face generation coal and gas are given prominence to, and produces pressure and affacts pressure sensor (5) last time; Pressure sensor (5) control hydraulic press (3) cuts out steel heavy air door (4) rapidly by hydraulic press (3); When the driving face breaking out of fire, high temperature or flue gas make high-temperature flue gas sensor (6) control motor, rapidly steel heavy air door (4) are closed by hydraulic press (3); When driving face generation floods, liquid level sensor (7) control hydraulic press (3) cuts out steel heavy air door (4) rapidly by hydraulic press (3); Thereby gas accident, fire incident, floods accident that driving face is taken place are controlled at minimum zone, and handle.

The place of driving face roadway automatic safety equipment will be installed earlier clear up, and driving face roadway automatic safety is equipped be installed in access adit is no more than 6 meters with the lining the scope, 0.2 meter of slotting is dark in the coal seam; Heavy supporting (1) is extend in the slotting of coal seam with 0.2 meter, lining; Realize that heavy supporting (1) and roadway wall (2) fixedly secure, the heavy air door (4) of all steel material open inward is installed again, in heavy supporting (1) to resist various disasters; Install and debug; Confirm errorless back unlatching air door, make air door be in normally open, promptly realize installing and using of driving face roadway automatic safety equipment.

Claims
