Abstract
The invention discloses a device for preventing one ventilation and three prevention accidents of a stope face in a comprehensive mode. The device is installed in an intake airway and a return airway of the stope face, arranged in range 30-50 meters away from the stope face, and used for preventing accidents such as fire, flood and coal and gas outburst on the stope face. The device is characterized in that a heavy support and roadway four walls are firmly fixed to be a whole through anchor bolts and anchor cables; two sets of steel heavy air doors are installed in the front and in the back of heavy support roadways of the roadway four walls and firmly connected with the heavy support to be a whole, and the steel heavy air doors are provided with emergency exits, the opening directions of the emergency exits are opposite to those of the steel heavy air doors; and the two sets of steel heavy air doors in the front and in the back are controlled by motors, and the motors are controlled by liquid level sensors. When the flood occurs on the stope face, water levels of the flood acts on the liquid level sensors, the liquid level sensors control the motors, and the motors can close the steel heavy air doors quickly.
Description
Technical field: comprehensive prevention stope " one through three prevention " accident 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.
Comprehensive prevention stope " one through three prevention " accident equipment, be installed in 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 the roadway wall, fixedly secured by anchor shaft anchor cable between heavy supporting and the roadway wall and be integrated, two cover steel heavy air doors are installed in 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 Electric Machine Control, motor is controlled by liquid level sensor, when stope generation floods accident, the floods water level is applied on the liquid level sensor, and liquid level sensor control motor cuts out the steel heavy air door rapidly by motor.
Comprehensive prevention stope " one through three prevention " accident equipment, it is characterized in that leaving belt conveyer on the 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, 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.
