Abstract

The utility model provides a comprehensive 'one-ventilation and three-prevention' accident preventing device of a coal face, which is mounted in the range of 30-50 m away from the coal face in an air inlet tunnel and an air outlet tunnel of the coal face, and is used for preventing the coal face from the accidents, such as fire disaster, flood, coal and gas outburst, and the like. The utility model is characterized in that: the device is firmly fixed with the four walls of the tunnel integrally by heavy brackets; the heavy brackets are firmly and integrally fixed with the four walls of the tunnel by anchor rods and anchor cables; two sets of heavy steel air doors are mounted in front of and in back of roadways of the heavy brackets of the four walls of the tunnel, and are fixedly and integrally linked with the heavy brackets; an emergency exit is mounted on each heavy steel air door; an opening direction of the emergency exit is opposite to an opening direction of the heavy steel air doors; the front and back heavy steel air doors are controlled by a pneumatic press of a high-pressure air tank; and the pneumatic press of the high-pressure air tank is controlled by a liquid sensor. When a flood occurs on the coal face, the liquid sensor is triggered by the water level of the flood so that the liquid sensor controls the pneumatic press of the high-pressure air tank, and the pneumatic press of the high-pressure air tank rapidly closes the heavy steel air doors.

Comprehensive prevention stope " one through three prevention " accident equipment

Technical field: comprehensive prevention stope " one through three prevention " accident 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.

The utility model content: the purpose of the utility model 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.

Comprehensive prevention stope " one through three prevention " accident equipment is installed in the advancing of stope, the return aircourse, within the scope of work plane 30-50 rice; Be used to prevent accidents such as stope fire, floods, coal and gas is outstanding, it is characterized in that: be one by fixedly securing between heavy supporting and the roadway wall, fixedly secure by anchor shaft anchor cable between heavy supporting and the roadway wall and be one; Two cover steel heavy air doors are installed in the front and back in the heavy supporting tunnel of roadway wall; And firmly be connected as one with heavy supporting, on the steel heavy air door escape hatch being installed, the opening direction of the opening direction of escape hatch and steel heavy air door is opposite; Front and back two cover steel heavy air doors receive the gas cylinder Gas Compressor Control; The gas cylinder aerostatic press is controlled by liquid level sensor, and when stope generation floods accident, the floods water level affacts on the liquid level sensor; Liquid level sensor control gas cylinder aerostatic press cuts out the steel heavy air door rapidly by the gas cylinder aerostatic press.

Prevention stope " one through three prevention " accident equipment; It is dark to it is characterized in that 0.2 meter of rib is stretched in heavy supporting, and the heavy air door doorframe between the heavy supporting and the connecting mode of heavy supporting are steel plate, link through screw; Steel heavy air door door leaf and doorframe match; Heavy air door doorframe and door leaf connect for strand, and door leaf and gas cylinder aerostatic press are closed door leaf through drive link, and sensor is through the operation of relay control gas cylinder aerostatic press.

Comprehensive prevention stope " one through three prevention " accident equipment; It is characterized in that leaving belt conveyer and drag conveyor import and export on the steel heavy air door that stope installs; Propelling along with stope; Comprehensive prevention stope " one through three prevention " accident equipment is every at a distance from 50 meters, moves forward once.

Comprehensive prevention stope " one through three prevention " accident 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.
