Controlling alarm alert, minimum ignition energy can occur gas explosion when reaching 0.28MJ.Wherein, down-hole oxygen
Concentration the most all therefore, when down-hole has certain density gas, spark can be there is more than 12% simultaneously, gas just has can
Can explode.At highly gassy mine, due to gas drainage under suction or wind arrange ability the most up to standard time, fire damp easily reaches quick-fried
Fried limting concentration, as long as therefore there being spark to produce, gas accident is just easy to occur, therefore at highly gassy mine, it is necessary to
Gas preventing and control is put and is grabbed as cardinal task.
When the gas density of down-hole is not more than 5%, running into spark will not explode, but device in Gas knows from experience the week at spark
Burn in limit；When fire damp concentration is 0.5%, now gas fully can react with oxygen, and the harm power of gas explosion is maximum；
But, when gas density is more than 16%, gas no longer has explosivity, when there is spark down-hole, can burn.Mine gas explosion
Also having certain relation with the temperature of down-hole, by experimental analysis, downhole temperature is when about 15 °, and gas is easy to blast.
Temperature sensor be installed at back, do not affect personnel and pass through, simultaneously the most again must and top, lane leave necessarily
Gap.Long-time monitoring continuously, and can be according to the pyrophoric gas marginal value in different collieries to coal seam spontaneous combustion prediction, for colliery
The preventing and controlling of freely burning fire and mine gas accident provide foundation.
Set up and improve coal spontaneous combustion monitoring method and means, strengthen the early prediction forecast work that coal spontaneous is got angry, in time
Measure gas, the situation of change of temperature, spontaneous fire is predicted forecast, nips in the bud.During the normal back production of work surface
Attach most importance to mainly for actual mining face goaf spontaneous combustion of float, it is contemplated that general mine all exists large area goaf, in view of
The preventive grouting preventing and extinguishing fire technology limitation to high-order fire preventing and treating, mine is typically taked based on preventive grouting, sprays
Retardant is auxiliary fire-fighting measure.When fltting speed is slow, work surface stops adopting or occurring spontaneous fire sign, carry out continuously
Property grouting, to fire-fighting measures such as nitrogen injection in goafs, control in time also to prevent spontaneous combustion of coal seam.Working face extraction terminate after should and
Time by standard close the goaf, and implement continuous enough grouting measures, spontaneous combustion do not occur leaving over float coal in guaranteeing goaf.?
Time near driving extremely old goaf, strengthen the monitoring to toxic and harmful, carry out Emergency Preparedness.
