Distributing Pattern of Temperature Field of Spontaneous Combustion and Five Region Position Method for Coal Pillar in Roadway

摘要：

For coal spontaneous combustion in roadway, the test drilling method is applied and then the mud fluid or water is grouted for rescue work in practice of coal mine. Fire source position is key for rescue work. However, because of the complexity of the influencing conditions, the researches on the correlative mechanism are not done further. Aiming to this problem, five kind patterns of coal spontaneous combustion in roadway are simulated to attain the roadways temperature field and temperature curve figure by applying the dynamic numerical simulation method. Then some conclusions are attained and can offer some help for fire source position and rescue work.
