Through application of the method, high-standard fast operation is achieved, and a safe work environment is also provided for the employees.
Description
Technical field
The present invention relates to airtight body of wall method for blocking under a kind of coal mine.
Background technology
In coal production process, must have rationally, the operation of efficient, science stable, ventilation system guarantee ventilation equipment and whole system reliably, thereby guarantee safety in production.Accomplish that this point need to build a large amount of ventilation walls and fire dam by laying bricks or stones, airtight body of wall is exactly conventional ventilation equipment, after work plane reclaims, for preventing Study on Protection of Spontaneous Combustion, needs to recovery operation Mian Ji lane, air way, seal in time simultaneously.Employing machine lane, air way seal simultaneously, can cut off rapidly goaf oxygen supply condition, can reach the complete totally enclosed shortest time in goaf, eliminate in time the hidden danger of spontaneous fire.At present, in the shutoff of coal mine down-hole tunnel, be all to adopt airtight body of wall conventionally, airtight body of wall to build by laying bricks or stones be conventionally all to build by laying bricks or stones in the tunnel of the discarded tunnel of needs or breaking out of fire, when airtight building wall, first dig foundation pit, then in foundation pit, build by laying bricks or stones.And there is inconvenience in building by laying bricks or stones of body of wall of sealing, along with building by laying bricks or stones of airtight body of wall, the draught area in tunnel reduces gradually, during particularly to last sealing, because draught area is too small, exist blast large, wind speed is high, and pernicious gas constantly increases, the operation needing to the staff who builds sealing body of wall by laying bricks or stones brings very big difficulty, because blast is large, the reason that wind speed is high, staff must wear anti-goggles just can carry out operation, finally when sealing, because of the wind speed in tunnel high, the airtight body of wall of the reason top that blast is large is difficult for building by laying bricks or stones, the building materials at airtight body of wall top can be blown off by high wind, and it builds position by laying bricks or stones, often need the repetition shutoff of 5-6 time, the integral body that just can complete airtight body of wall is built by laying bricks or stones, and due to the building by laying bricks or stones of top of sealing body of wall, cannot build by laying bricks or stones according to the program of building by laying bricks or stones normally, be difficult to the masonry quality that reaches desirable.Staff is when building airtight body of wall top by laying bricks or stones, need built on stilts to carry out operation, when work high above the ground, blast is large, wind speed is high, and pernicious gas constantly increases and staff can not adopt normal work position to carry out work, bring hidden danger and increase intensity of workers to staff's safety, also can bring infringement to staff's health.
Summary of the invention
The shortcoming existing for prior art, the invention provides airtight body of wall method for blocking under a kind of coal mine, and the method can be carried out shutoff to work plane or Abandoned Tunnel fast and efficiently.
Technical scheme of the present invention is such realization: airtight body of wall method for blocking under a kind of coal mine, comprises the following steps:
(1), in the tunnel of discarded tunnel or breaking out of fire, determine the position of building by laying bricks or stones of airtight body of wall;
(2) according to the position of building by laying bricks or stones of airtight body of wall, draw after benchmark wall line, according to benchmark wall line, dig foundation pit, in foundation pit, build airtight body of wall by laying bricks or stones, when the height of airtight body of wall is built by laying bricks or stones to ground line position, tunnel, reserved body of wall reserved opening on airtight body of wall, the size of described body of wall reserved opening be airtight body of wall the gross area 1/4th to 2/5ths, the thickness of described airtight body of wall is 500-800mm;
(3) closing door body is installed in body of wall reserved opening, described closing door body is comprised of door-plate and rotating shaft part, and the rotating shaft part on described closing door body is fixed in body of wall reserved opening, makes closing door body by rotating shaft part and sealing wall connecting;
(4) open the door-plate of closing door body in body of wall reserved opening, continue to build by laying bricks or stones airtight body of wall;
(5) when airtight building wall completes, close after the door-plate of closing door body in body of wall reserved opening, then the closing door body that masonry panel reserved opening place arranges divides.
Further, 1/3rd of the gross area that the size of described body of wall reserved opening is airtight body of wall.
Further, described closing door body adopts fire proofing to make.
Further, the building materials of described airtight body of wall is stone or brick.
The invention has the beneficial effects as follows: the present invention adopts reserved breach on the airtight body of wall of building by laying bricks or stones, in breach inboard, fix a door, when breach is reserved in the end shutoff, close door, by door, cut off object distinguished and admirable, that the realization of reduction blast is fast and safely sealed.The present invention is simple in structure, practical and convenient, without using other energy, has avoided employee to damage under high Action of Wind pressure healthy.The application of the method, realizes high standard sharp work, also for employee provides safe working environment.
