Description
Technical field：
The present invention relates to coal mine gob monitoring technical field more particularly to a kind of energy based on online infrared thermal imager
It is enough that the monitoring device of comprehensive visualizing monitor, system and method are carried out to goaf coal spontaneous combustion temperature field.
Background technique：
The occurrence and development of goaf coal spontaneous combustion are extremely complex, a dynamic change, the physical chemistry automatically speeded up
Process.This process includes chemical dynamics process, fluid permeability and the process of diffusion, mass transfer process, thermal procession
And the process of heat transfer, the phenomenon that this complicated, comprehensive function can be illustrated there has been no complete theory so far and its rule.Coal is certainly
Combustion process is not only related with the oxidisability of coal itself and exothermicity, also with leak out oxygen supply and accumulation of heat environment it is closely related.Coal spontaneous combustion
It is this process to contradiction active development of coal body heat release and function of environment heat emission, with the development of Coal Self-ignition Process, coal is intracorporal various
Parameter is all changing, and position, temperature, leakage intensity and the oxygen concentration in turn resulting in high-temperature area are sent out at any time vivo to be changed
Become.Coal spontaneous is under fire, and the complexity to form environment, the concealment of high temperature fire source are monitored to spontaneous combustion of coal seam, forecast brings and is greatly stranded
Difficulty causes the development of such current technology to relatively lag behind, while also constraining the development of coal spontaneous combustion fire protection technologies.In reality
Under the conditions of, be difficult to determine how many days spontaneous combustion can occur for coal, which kind of degree spontaneous combustion high-temperature region develops to, flame range range have it is much,
How high temperature zone position and its temperature are known in the early stage of spontaneous combustion of coal seam and flame range governance process, the effect after implementing fire extinguishing engineering
How, how to investigate, flame range extinguish after why can re-ignition, flame range can re-ignition etc. under the conditions of what kind of.These problems are
The prevention of spontaneous combustion of coal seam and control bring many puzzlements.
Coal spontaneous combustion monitoring be exactly after seam mining, according in coal spontaneous combustion process temperature rise, gas discharge etc. characteristic informations,
Sentence and know spontaneous combustion state, judge armed position, realizes coal spontaneous combustion real-time monitoring, forecast, and provide alarm before disaster expansion.It is
The basis of mine fire prevention and processing is the key that the prevention and treatment of mine coal seam fire, occupies extremely important status.It is down-hole coal bed
Fire forecast it is more early, more accurate, then the required human and material resources that stamp out a fire are fewer, and rescue is also easy.As long as can it is accurate,
The early warning in time carrying out coal bed fire can accomplish the measure for taking prevention coal bed fire with a definite target in view, improve measure
Specific aim and validity, to improve the economic benefit of Coal Mine Fire engineering.
The temperature mainly generated to spontaneous combustion process and gas are monitored to goaf at present, wherein temperature monitoring mainly includes
The technologies such as conventional temperature sensor thermometric, infrared measurement of temperature and wireless sensor network thermometric.Gas-monitoring is mainly ground beam tube
Monitoring, in the practical application of coal mine, the application status of Tube Bundle Monitoring System be not it is especially good, even without performance it is due
Effect, to find out its cause, being primarily due to monitor main heart setting on ground, sampled point is farthest up to 30KM apart from monitoring center, it is desirable that
Pipeline has the following aspects problem without gas leakage：Monitoring data have certain time lag, monitor system to spontaneous fire
Gas marker selection less pertinence, underground pipeline gas leakage, beam tube sampling point be easy ponding dust accumulation even smashed.
Whether optical fiber temperature-measurement or bound polyamine are to be monitored to the partial dot in goaf, and goaf is empty
Between it is very big, any one position is likely to that spontaneous combustion occurs, although coal mine fire fighting technology is more mature, being a lack of one really has
The monitoring technology of effect, it is difficult to be quickly found out actual high temp fire source point, therefore cannot quickly put out a fire, often expend a large amount of
Manpower and material resources.

Vi.j(k+1)=Vi.j(k)+c1r1(Pi,j(k)-Xi.j(k))+c2r2(Pg.j(k)-Xi.j(k)) (3)
Wherein, work as Vi, when j > Vmaxi, j, a certain component V i, j, the j ∈ (1, D) of Vi, j=Vmaxi, j, i.e. particle i is had exceeded
The limitation of particle rapidity range [Vmin, Vmax], then need to pull it back by force for particle rapidity upper limit Vmax it is inclined on j
Amount；
Six, the judgement whether algorithm terminates：Check the global optimum position in group whether within an acceptable error range or
Whether searching times reach the maximum value of setting, if met the requirements, EP (end of program), output population global optimum position is
Required optimal solution, otherwise, jump procedure two continue next iteration search.
