大南湖一矿采空区煤自燃预警气体指标研究

Study on Early Warning Gas Index of Coal Spontaneous Combustion in Goaf of Dananhu No.1 Coal Mine

为解决大南湖一矿面临的较为严重的煤自燃风险问题,通过煤自燃标志性气体测试设备对大南湖一矿1307工作面煤样煤自燃过程中的标志性气体进行了分析研究,确定了煤自燃不同阶段的标志性气体及其生成规律,并确定了不同标志性气体的预警温度,相关研究为1307工作面煤自燃的科学预警奠定了基础。

In order to solve the serious risk of coal spontaneous combustion faced by No.1 Coal Mine of Dananhu,the symbolic gas in the process of coal spontaneous combustion in the 1307 working face of No.1 Coal Mine of Dananhu was analyzed and studied by the symbolic gas test equipment of coal spontaneous combustion.The symbolic gas and its generation law in different stages of coal spontaneous combustion were determined,and the early warning temperature of different symbolic gas was determined.The related research has laid a foundation for the scientific early warning of coal spontaneous combustion in the 1307 working face.
