Abstract

The invention discloses full-automatic safety equipment for a stope face roadway. The full-automatic safety equipment is arranged in a range which is six meters into an air inlet and return throat of a stope face, and is used for preventing accidents such as fire, flood, and coal and gas outburst on the stope face. The full-automatic safety equipment is characterized in that: heavy supports are firmly fixed integrally with four walls of the roadway; a steel heavy air door is arranged between the heavy supports on the four walls of the roadway, and is controlled by using a hydraulic machine; the hydraulic machine is controlled by using a pressure sensor; and when coal and gas outburst accidents occur on the stope face, gas pressure acts on the pressure sensor, the pressure sensor is used for controlling the hydraulic machine, and the hydraulic machine is used for closing the steel heavy air door rapidly.

Description

Coalface well lane full-automatic safety equipment

Technical field: Coalface well lane full-automatic safety 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.

Coalface well lane full-automatic safety equipment, be installed in advancing of support in gateway of coal mining face, the return airway road junction is inward in 6 meters the scope, in order to prevent the stope 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 stope 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.

Coalface well lane full-automatic safety equipment 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 Coalface well lane full-automatic safety equipment power supply, when the down-hole restores electricity, and the automatic disconnection of batteries power supply.

Coalface well lane full-automatic safety equipment compared with prior art has the following advantages:

1, Coalface well lane full-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 move with the movement of stope, 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 Coalface well lane full-automatic safety equipment can with the underground monitoring Monitor-Networking, and be transferred to ground and carry out Artificial Control and open.

7, Coalface well lane full-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: Coalface well lane full-automatic safety equipment 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: Coalface well lane full-automatic safety equipment, be installed in advancing of stope, the return airway road junction is inward in 6 meters the scope, in order to prevent the stope 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 stope 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 Coalface well lane full-automatic safety equipment will be installed is cleared up, Coalface well lane full-automatic safety equipment 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 Coalface well lane full-automatic safety equipment.
