Abstract
Equipment for comprehensively preventing 'ventilation, gas outburst prevention, dust prevention and fire prevention' accidents of a stope face is mounted in an air inlet and return tunnel of the stope face, and is used for preventing the accidents such as fire, flood, coal and gas outburst and the like of the stope face within the distance ranging from 30 meters to 50 meters. The equipment is characterized in that a heavy support and the peripheral wall of a roadway are firmly fixed into a whole through anchor rods and anchor cables, two heavy steel air doors are mounted in the front and in the rear of a heavy support tunnel on the peripheral wall of the roadway and are firmly and integrally connected with the heavy support, an emergency exit is mounted on each heavy steel air door, the opening direction of each emergency exit is opposite to that of the corresponding heavy steel air door, the front heavy steel air door and the rear heavy steel air door are controlled by motors, the motors are controlled by high-temperature flue gas sensors, high temperature or flue gas acts on the high-temperature flue gas sensors when the stope face has a fire accident, the high-temperature flue gas sensors control the motors, and the motors rapidly close the heavy steel air doors.
Description
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.
Summary of the invention: the objective of the invention 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 Electric Machine Control; Motor is by the control of high-temperature flue gas sensor, and when stope breaking out of fire accident, high temperature or flue gas affact on the high-temperature flue gas sensor; High-temperature flue gas 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 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.
