Identification method for the risk area of spontaneous combustion of residual coal in goaf of fully-mechanized caving face with spontaneous combustion coal seam
The coal seam of N4107 fully-mechanized caving face in Shaduanzi Coal Mine is spontaneous combustion coal seam,and there is a lot of residual coal in the goaf,which is prone to natural combustion accidents.In order to effectively prevent the hidden dan-ger of spontaneous combustion of residual coal in the goaf of the working face,the scientific division of the"three zones"of spontaneous combustion of residual coal in the goaf was carried out,and simulation verification was carried out using Fluent software.Combined with the characteristics of residual coal in the goaf,the distribution law of high-risk areas for spontaneous combustion of residual coal in the goaf was identified,providing a scientific basis for effective prevention and control of spontaneous combustion in the goaf.
