At present, among actual life, the demand of coal is very big, appeared in the storage management process of coal is worked as
Spontaneous combustionof coal phenomenon be very sixty-four dollar question.Efficiently such problem or prevention are found in time, avoids such problem
Occur to reduce the problem of unnecessary loss is current critically important.
During the storage management of dump, more traditional way is to can't detect the temperature conditions inside dump,
Can only artificially make an inspection tour to detect whether dump emits smoke, if smoldering, then start manually that temperature is high
The coal of calcination, which is dug out, to be come, but until dump starts to smolder, the part inside dump early begins to burn in fact, and coal combustion
The smog released is also to start for a long time just to come up after burning in coal in fact.So when seeing that dump is smoldered, then table
Bright coal early has started to burn.As can be seen that traditional method is not still avoided that bigger loss.
Existing dump nature forecasting technique is to enter in dump low-temperature oxidation from after Warm status, and dump is smoldered or occurred bright
Before fire, according to the feature such as gas marker, temperature change caused by oxidation of coal heat release, forecasting coal self-ignition fatalness state is simultaneously
The technology of early warning is carried out, the forecasting procedure currently used for spontaneous combustionof coal early stage mainly has optical fiber temperature-measurement method, symbolic gas analytic approach
