Description

Autoreaction generates the goaf fireproof fire-extinguishing device and method of carbon dioxide
Technical field
The invention belongs to underground coal mine spontaneous combustion diaster prevention and control technical field, and titanium dioxide is generated more particularly to a kind of autoreaction The goaf fireproof fire-extinguishing device and method of carbon.
Background technology
The freely burning fire of coal is one of most important threat of coal production.In China emphasis colliery, about 50% Mine exist spontaneous combustionof coal danger, the 94% of mine fire total degree is spontaneous combustionof coal, and wherein spontaneous combustion in goaf accounts for 60%.At present, the method for heterogeneous goaf fire preventing and treating is more, one of most widely used method, i.e., is injected to goaf lazy Property gas, to reduce goaf oxygen concentration, reaches fireproof fire-extinguishing purpose.
Carbon dioxide as inert gas has absorption resistance oxygen, inerting drop during heterogeneous goaf fire hazard treating The multi-effects such as oxygen, if directly pressure injection liquid carbon dioxide, is also acted on obvious absorbing and cooling temperature, for suppressing coal oxidation The further development of spontaneous combustion has remarkable result.
The method that tradition injects carbon dioxide to goaf is broadly divided into two kinds:One kind is by liquid dioxy on ground After changing carbon gasification, the mode that goaf is injected is delivered to by the road;Another kind is in underground that liquid carbon dioxide is direct Inject the mode in goaf.Above two mode is by Pipeline transport, selects suitable liberation port position to be injected into mined out Area.From links such as the preparation of carbon dioxide, storage, transport, releases, whole system is more complicated, and cost is higher.
