Description
Technical field
The present invention relates to a kind of method of coal mine gob infrared radio thermometric, it is serious to be related to coal body auto-ignition, mined out
The monitoring method technical field of spontaneous combustion caused by area's bad sealing and highly gassy mine goaf temperature.
Background technique
Coal spontaneous combustion not only results in waste of resources, environmental disruption and economic loss, but also it is serious to may cause personal injury etc.
Consequence.Goaf is the easy key area that coal spontaneous combustion occurs, and therefore, the early monitoring of the region coal spontaneous combustion is particularly significant, thermometric
Method belongs to spontaneous combustionof coal monitoring technology.
Currently, the basic principle of temperature measurement is by measuring the characteristic value of certain substance related with temperature to obtain
Whether temperature value with physical contact between media can be divided into contact temperature-measuring method and contactless temperature-measuring method according to it.Contact
It is several that formula temp measuring method can be divided into contact photoelectric or thermocolour thermometric, expansion type thermometric, electricity quantity type thermometric etc. again；It is contactless
Temp measuring method can be divided into sound wave or microwave temp measuring method, infrared measurement of temperature method, laser interference formula temp measuring method, spectroscopic temperature measurement side
Several classes such as method.Photo-electric thermometric corollary system is expensive, bulky, limits it in the application of coal mine fire zone.Thermocolour is surveyed
The temperature indicating paint and temperature indicating liquid crystal disadvantage of middle benefit gas are more, it is difficult to apply to flame range survey.Warm expansion type temp measuring method is cold using heat expansion
The principle of contracting measures temperature, and expansion type temperature measuring device includes pressure-type thermometer, glass liquid thermometer, bimetallic expansion type
Thermometer.3 quasi-instrument is cheap, conveniently, and measurement is accurate, reading is intuitive, structure is simple, but the above two are long response times, damage
Mistake is big, be not easy to maintenance, transmitting range is close, precision is lower, influenced by the external world, the latter does not have to narrow space thermometric generally.Electricity
The principle of amount formula temp measuring method is mainly the potential for utilizing material, the original of resistance or other electrical properties and the single valued relation of temperature
Reason is to carry out thermometric.Including the methods of electric thermo-couple temperature measurement, thermal resistance and thermistor temp measurement.Thermocouple is substantially
The characteristics of being able to satisfy flame range thermometric, but its is perishable, noise immunity is poor, is easily damaged；Thermal resistance superior performance, in middle cryogenic conditions
Lower use is more accurate, has a variety of kinds, such as platinum, copper resistance, can be used for the measurement of flame range temperature, but general resistance to mechanical energy
Power is poor, larger intolerant to burn into structural elements, and dynamic response is poor；Thermistor interchangeability is poor, non-linear serious, and stability is not yet
Good, temperature-measuring range is 50 DEG C~300 DEG C, is having the high temperature such as open fire area that cannot be applicable in.The transmission line of three is also harder, is not easy to
It is put into blasthole.Sound wave or microwave thermometric are influenced by the external world, are not suitable for applying to flame range thermometric.Laser interference formula thermometric is surveyed
What amount method measured is essentially all the mean temperature measured in blasthole on laser emission path, and is involved great expense, and is not easy to take
Band, thus laser interference formula thermometric is difficult to use in flame range thermometric.Spectroscopic temperature measurement method is generally used for measurement high-temp combustion stream
The thermometric of the complex flowfields such as field, plasma, flame, measured temperature is relatively high, is affected by external environment, and price is high
Expensive, thermometric has little significance in flame range.Therefore the technology has highly important meaning to the monitoring prevention of goaf coal spontaneous combustion
Justice.
