Study on Spontaneous Combustion of Veinlet Belt of Dachang Copper Pit Mine

摘要：

Aiming at the problem of spontaneous combustion in Veinlet Belt of Coppor Pit Mine, this paper put forward a new flame retardant method. The reasons and mechanism of spontaneous eombustion were discussed based on the investigation of geological conditions and mining process. By pilot experiments, parameters of moisture of NCZ-1 fire agent, combustion performance of carbonaceous shale and other indexes of sulfide ores in Copper Pit Mine were determined. And small,scale in-situ test proved that the inhibiting time of NCZ-1 fire agent time can be up to 7 to 10 days.
