Abstract

The invention discloses full-automatic safety equipment of an extraction working face well roadway, which is arranged within the range from an air intake roadway junction and an air returning roadway junction deep into 6 meters and is used for preventing accidents of the extraction working face, such as fire disasters, flood, outburst of coal and gas and the like. The full-automatic safety equipment of the extraction working face well roadway is characterized in that a heavy support and four walls of a well roadway are firmly fixed into a whole; a steel heavy air door is arranged among the heavy supports on four walls of the well roadway; the steel heavy air door is controlled by a hydraulic machine; the hydraulic machine is controlled by a water-level sensor; when the extraction working face encounters the flood accident, the water level of the flood accident is acted upon the water-level sensor, the hydraulic machine is controlled by the water-level sensor, and the steel heavy air door is quickly closed by the hydraulic machine.

Description

Stope roadway automatic safety equipment

Technical field: stope 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.

Stope roadway automatic safety equipment is installed in the advancing of support in gateway of coal mining face, return airway road junction inward in 6 meters the scope, accident such as gives prominence in order to prevention stope fire, floods, coal and gas; 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 controlled by liquid level sensor; When stope generation floods accident; The floods water level affacts on the liquid level sensor, and liquid level sensor control hydraulic press cuts out the steel heavy air door rapidly by hydraulic press.

Stope 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 stope roadway automatic safety, when the down-hole restores electricity, and the automatic disconnection of batteries power supply.

Stope roadway automatic safety 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.

Description of drawings:

Fig. 1: stope roadway automatic safety equipment sketch map.

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

4, heavy air door; 5, liquid level sensor.

The specific embodiment: existing is the example explanation with the accompanying drawing: stope roadway automatic safety equipment; Be installed in the advancing of stope, return airway road junction inward in 6 meters the scope; Accident such as give prominence in order to prevention stope fire, floods, coal and gas, 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 liquid level sensor (5) control, and when stope generation floods accident, the floods water level affacts on the liquid level sensor (5); Liquid level sensor (5) control hydraulic press (3) cuts out steel heavy air door (4) rapidly by hydraulic press (3).

The place of stope roadway automatic safety equipment will be installed earlier clear up, and stope 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 stope roadway automatic safety equipment.
