Description
Technical field
The present invention relates to a kind of trapezoidal fire dam of mine anti-explosion and its construction method, it is adaptable to which tunnel occurs blast, fire
Have little time to construct the situation or gas emission of conventional containment wall than larger mine during etc. heat power disaster.
Background technology
Coal has played particularly important work as one of the main energy sources of the world today in human being's production and life
With.However, coal faces the threat of various natural calamities in exploitation, accumulating and application process, the peace of coal has been had a strong impact on
Full production and utilization.Mine fire is one of major casualty form therein, can burn substantial amounts of coal resources and equipment, is produced
A large amount of high-temperature flue gas and pernicious gas, jeopardize the life security of underground work personnel, and severe patient can also trigger gas, coal dust quick-fried
It is fried, cause bigger disaster.There is concrete on fire in colliery, when such as can not directly put out a fire, it is necessary to which flame range is closed.
Fire dam traditional at present is constructed using materials such as loess, brick, cement and formed mostly, constructs 1m3Such fire dam
Need 400 pieces of bricks, 0.3m3Cement, due to fire dam be by the material such as fragment of brick and cement, sand linking form, thus intensity compared with
Difference, easily leaks out, and labor strength is high, quantities is big, the construction time is long, inefficiency, directly affects colliery catastrophe
Rescue efficiency.In recent years, some researchers have angularly carried out research from construction material, construction method, fire dam adjunct,
Mainly include air bag/filling airbag fire dam and fill-type fire dam.Wherein, air bag/filling airbag fire dam work progress letter
It is single quick, air bag/filling airbag need to be only put into and treat closed area and then start compressed-air system, but mainly construct raw material
Not the standing goods and materials in underground, are required to according to the different different size of airbag/utricules of setting of drift section before constructing, and tunnel
Section complexity is various, therefore higher to air bag/filling airbag technological requirement, and can not process in advance, and limitation is uncomfortable than larger
The need for promptly being constructed under catastrophic condition；Further, since drift section is complicated, often in the presence of some sharp objects with corner angle,
Air bag used/filling airbag gas leakage is easily caused, thus there is potential safety hazard, and be difficult to the heat power disaster punching such as resistance shock wave
Hit, the seeervice cycle is limited.The implementation of fill-type fire dam generally first constructs interior using materials such as steel plate, plank or masonries
Exterior wall forms cavity, and fire dam is ultimately formed after then being filled to pouring material in cavity again.In implementation process, due to interior
Exterior wall is constructed and needs to use steel plate, plank or fragment of brick more, and the external and internal wall constituted using plank is because its inflammability is easy
Potential safety hazard is left, and is constructed external and internal wall using steel plate or fragment of brick and is spent big and take time and effort, and the obturation that early stage is used
Raw material setting time is more long, it is impossible to the need for meeting urgent constructing.To sum up, there is former material in existing fire dam and its construction method
Material transport complexity, high cost, time and effort consuming, cannot meet an urgent need or construct quality be difficult to meet for a long time it is closed the need for, it is impossible to completely
The need for the sufficient great heat power disaster catastrophe period efficient emergency management and rescue of mine.
