The fire monitoring technology is meant after exploitation under the coal mine, according to the intensification of coal in spontaneous combustion process, discharge variation characteristic such as gas, differentiates the spontaneous combustion state, spontaneous combustion is got angry discern and the technology of early warning.
The index gas analytic approach is to forecast the main method of fire at present both at home and abroad.Coal discharges gases such as carbon monoxide, carbon dioxide, alkane, alkene and alkynes in spontaneous combustion process, in view of gas drift and good penetrability, therefore, analyze judgement coal spontaneous combustion degree through gas index and have important value.
But; Multiple gases to the coal spontaneous combustion process discharges is all carried out data acquisition, analysis; Judge the spontaneous combustion situation of coal again; One side needs to increase sensors of various types, and analysis and determination methods complicacy and possibility produce the different predicting result because of multiple gases on the other hand, thereby makes the colliery real conditions be difficult to judge.Therefore; A kind ofly be enough to judge that spontaneous combustion gets angry the gas property gas as a token of of sign if find; And, will reduce the cost of monitoring system and simplify software alarm decision method, improved the accuracy of judging according to the law forecasting fire that gas marker changes.
Utility model people gets angry simulated experiment on the spontaneous combustion of coal simulator stand, experimental facilities mainly comprises body of heater, gas monitoring system, temperature monitoring system and control system etc.Through which kind of can run through spontaneous combustion process all the time and can embody the significant concentration variation in natural different phase in the gas of simulated experiment comparison coal spontaneous combustion generation.
Like Fig. 1-shown in Figure 6, can find out that from above-mentioned curve CO gas is got angry process through whole coal spontaneous, the coal temperature discharges the carbon monoxide that can measure in time more than 50 ℃, and the carbon monoxide output is along with the sharply rising of coal temperature.The time that alkane (methane, ethane, propane) occurs is almost synchronous with carbon monoxide, but its concentration is low, and the different rules that manifests is arranged in different coals; Olefin gas occurs lately than carbon monoxide and paraffin gas, and ethene can be measured about 110 ℃, is that coal spontaneous is got angry the whether symbolic gas in accelerated oxidation stage of process; The time that alkynes gas occurs only just occurs in the higher temperature section the latest.
From the early stage property and the consideration of gas monitoring property of coal spontaneous ignition forecast, utility model people confirms that carbon monoxide is a native system monitoring coal spontaneous combustion gas marker, also is sealing-tape machine fire forecast gas marker simultaneously.
Measuring the colliery variations in temperature is to judge the foundation of coal spontaneous combustion generation and developing stage.Thermometry is meant utilizes temperature pick up that temperature monitoring is carried out in tested place, confirms coal and ambient temperature situation of change, predicts fire with this.Thermometry mainly is divided into two kinds: the one, through direct monitoring coal column, goaf multiple spot districution temperature, set up the goaf models for temperature field, and resolve and confirm coal spontaneous combustion hidden danger point (or burning things which may cause a fire disaster point); The 2nd, through continuous monitoring sealing-tape machine hidden danger point temperature early prediction fire.Temperature is as auxiliary fire forecast parameter, and the raising system forecasts reliability.
At last, to leak out be the necessary condition of coal spontaneous combustion fire in the goaf.Through inside and outside the continuous monitoring citadel or the variation of other key position draught head, for accurate forecast colliery underground fire provides auxiliary reference.
