Abstract
A device for comprehensively preventing one ventilation and three prevention accidents of a stope face is installed in an air inlet roadway and an air return roadway of the stope face, the distance between the accident equipment and the stope face is within the range of 30-50m, and the equipment is used for preventing the stope face from accidents of fires, flood, coal and gas outburst and the like. The accident equipment is characterized by being firmly fixed into a whole with walls of a laneway through heavy supports, the heavy supports and the walls of the laneway are firmly fixed into a whole through a bolt-anchor, two sets of steel heavy air doors are installed in the front and the back in the roadway of the heavy supports of the walls of the laneway and are firmly connected into a whole with the heavy supports, an emergency exit is installed on each steel heavy air door, the starting direction of each emergency exit is opposite to the starting direction of the steel heavy air doors, and the front set of the steel heavy air door and the rear set of the steel heavy air door are controlled by a high-pressure gas cylinder aerostatic press which is controlled by a liquid level sensor. When the accident of flood happens on the stope face, a water level of the flood acts on the liquid level sensor, the liquid level sensor controls the high-pressure gas cylinder aerostatic press to quickly close the steel heavy air doors.
Description
Technical field: comprehensive prevention stope " one through three prevention " accident equipment belongs to a kind of safety equipment of installing in coal mine down-hole tunnel, is specially adapted under 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 is mainly also shutoff that floods occur, and the measure means are a lot of when coal and Gas Outburst occur, disaster can't be controlled 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.
comprehensive prevention stope " one through three prevention " accident equipment, be arranged on advancing of stope, in the return aircourse, within the scope of work plane 30-50 rice, be used for prevention stope fire, floods, the accident such as coal and Gas Outburst, it is characterized in that: be integrated by fixedly securing between heavy supporting and roadway wall, fixedly secured by anchor shaft anchor cable between heavy supporting and roadway wall and be integrated, two cover steel heavy air doors are arranged on the front and back in the heavy supported laneway of roadway wall, and firmly be connected as one with heavy supporting, on the steel heavy air door, escape hatch is installed, the opening direction of escape hatch is opposite with the opening direction of steel heavy air door, front and back two cover steel heavy air doors are subjected to the gas cylinder Gas Compressor Control, the gas cylinder aerostatic press is controlled by liquid level sensor, when stope generation floods accident, the floods water level is applied on liquid level sensor, liquid level sensor is controlled the gas cylinder aerostatic press, rapidly the steel heavy air door is closed by the gas cylinder aerostatic press.
Comprehensive prevention stope " one through three prevention " accident equipment, it is characterized in that leaving belt conveyer on steel heavy air door that stope installs and drag conveyor is imported and exported, propelling along with stope, comprehensive prevention stope " one through three prevention " accident equipment moves forward once every 50 meters.
Comprehensive prevention stope " one through three prevention " accident 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, due to hanging in advance of each sensor, provide 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 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.
