Spontaneous combustion of coal mined-out area and its mechanism of control research

LU Guobin,GENG Ming(College of Resource and Environment Engineering,Liaoning Technical University,Fuxin 123000,China)  
As the improvement of mechanization level and producing rate in coal mining,the residual coal of goaf increased and expansion,the hidden danger of spontaneous combustion in goaf become more serious.By analyzing the different viewpoints of domestic and abroad scholars,the phases of coal self-ignition are put forward,that is latency phase,self-heating phase and self-ignition phase,and also pointed out the three conditions of coal spontaneous combustion.According to research on self-ignition theory,propose four kinds of measures: grouting extinguishing fire,uniform pressure extinguishing fire,inhibitor extinguishing fire and inert gas extinguishing fire.
