Spontaneous Combustion Characteristics and Integrated Control Technique in Tiefa Coal Seam
Abstract：In Tiefa 8 production mine,the identification experimental results of coal spontaneous combustion tendency in Daxing,Xiaonan,Dalong coal mine were class Ⅰ,easy to spontaneous combustion,spontaneous combustion tendency of other mines as Class Ⅱ.The spontaneous combustion problems in the mining process are more prominent.According to the technical route of ＂basic law to study-forecasting method to determine-prevention and control technology system to establish＂,this paper has formed a comprehensive prevention and control technology system with Tiefa characteristics that integrated nitrogen injection with injected sand plugging closely.
