Abstract: The coal mine natural ignition monitoring system mainly has monitoring system,beam tube monitoring system,manual detection and other methods. Coal mine spontaneous combustion tube monitoring system is one of the main system of coal mine spontaneous combustion prediction. Through the spontaneous combustion gas detection of goaf and other area,master the gas components,analyze the spontaneous combustion law for early warning of spontaneous combustion risk,and provide the basis for fire prevention measures. Through the development and improvement in recent years, the coal mine spontaneous combustion beam tube monitoring system has realized 24 hour online monitoring,but there are still impure gas samples,tube leakage,equipment operation error,unreasonable pipeline layout,and inappropriate goaf extraction protection.Specific optimization improvement measures are put forward,effectively solving the defects of coal mine spontaneous combustion beam tube monitoring system management,and better serving coal mine spontaneous combustion monitoring.
