Abstract
The utility model provides full automatic safety equipment of a well lane of a stope working face, which is mounted at an air inlet laneway adit and an air return laneway adit of the stope working face and used for preventing and controlling the occurrence of accidents of 'one ventilation and three prevention' of the stope working face. The automatic safety equipment is characterized in that the automatic safety equipment is firmly fixed to form a whole between heavy supports and the four walls of the well lane, wherein a steel-made heavy air door controlled by a gas compressor of a high pressure gas cylinder is mounted among the heavy supports surrounded by the four walls of the well lane; and the gas compressor of the high pressure gas cylinder is controlled by a pressure sensor, a high temperature flue gas sensor or a liquid level sensor, so that gas accidents, fire disaster accidents, flood disaster accidents occurring to the stope working face are controlled within the minimum range and treated.
Description
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.
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.
Stope roadway automatic safety equipment; Be installed in that stope advances, the return airway road junction; In order to the generation of prevention and control stope " one through three prevention " accident, it is characterized in that being that by fixedly securing between heavy supporting and the roadway wall one, steel heavy air door are installed between the heavy supporting of roadway wall; The steel heavy air door receives the gas cylinder Gas Compressor Control; The gas cylinder aerostatic press is by pressure sensor or high-temperature flue gas sensor or liquid level sensor control, when stope generation coal and gas are given prominence to, and when producing pressure and affacting on the pressure sensor; Pressure sensor control gas cylinder aerostatic press cuts out the steel heavy air door rapidly by the gas cylinder aerostatic press; When the stope breaking out of fire, high temperature or flue gas make high-temperature flue gas sensor control gas cylinder aerostatic press, rapidly the steel heavy air door are closed by the gas cylinder aerostatic press; When stope generation floods, liquid level sensor control gas cylinder aerostatic press cuts out the steel heavy air door rapidly by the gas cylinder aerostatic press; Thereby gas accident, fire incident, floods accident that stope is taken place are controlled at minimum zone, and handle.
Stope roadway automatic safety 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.
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.
