Graham Sodd method of investing coefficient is mainly used in the judgement of spontaneous combustion of coal situation.The value of Graham Sodd method of investing coefficient G in 0.7～3.0 scope for evaluate coal spontaneous combustion and again spontaneous combustion process be significant.For each stage relevant to coal self-heating procedure, be suitable for the following criterion based on Graham Sodd method of investing coefficient:

1. in the time of Graham Sodd method of investing coefficient value G >=0.7 and G≤1.0, the degree of oxidation of coal increases, and coal temperature is than the remarkable increase of primitive rock temperature, and temperature reaches 60 ℃;

2. in the time of Graham Sodd method of investing coefficient value G >=1.0 and G≤2.0, fire hazard increases, and coal temperature reaches more than 80 ℃, should take preventive measures;

3. in the time of Graham Sodd method of investing coefficient value G >=2.0 and G≤3.0, coal heating is serious, and coal temperature reaches more than 180 ℃, must take conventional fire prevention measure;

4. in the time of Graham Sodd method of investing coefficient value G >=3.0, almost can there is naked light in coal certainly, and coal temperature, more than 300 ℃, must be taked fire extinguishing measure;

For the temperature of spontaneous combustion of coal point, be also simultaneously 300 ℃ of the minimum temperature of fire, Graham Sodd method of investing coefficient value G=3.0.Conventionally the fire under coal mine is all the fire not exclusively developing.The incomplete development point of fire is the terminal in fire development stage, is again the starting point that fire extinguishes the stage.

Fire hazard recognition methods can judge index gas content according to coal kind in addition.From the angle of gas analysis, the symbolic gas index of each coal is as follows:

The representative C of olefin gas ₂h ₄the oxidation that can be considered as coal enters the symbolic gas in self-heating stage really, under the prerequisite that has CO to exist, as long as there is C ₂h ₄the forecast of spontaneous fire of can producing coal, as warning index.

The appearance of alkynes gas, means that coal has entered or has been about to enter combustion phases, as long as C detected ₂h ₂just can conclude the naked light that in monitoring section, existence has been burnt, the naked light alarming index that therefore can get angry using it as coal spontaneous, also can be used as simultaneously and judge that coal spontaneous ignition extinguishes the index of degree.
