摘要
针对目前煤与瓦斯突出危险预警在预警实时性、准确性和便捷性方面的需求,分析了煤岩破坏电磁辐射特征、规律及煤与瓦斯突出过程电磁辐射、常规预警指标变化规律及其相关性,开发了煤与瓦斯突出电磁辐射预警装备及软件,建立了煤与瓦斯突出电磁辐射预警准则,实现了煤与瓦斯突出演化过程电磁辐射的自动分析及预警。研究结果表明:电磁辐射指标与常规预警指标具有较高的正相关性,可以反映煤与瓦斯突出危险性,现场煤与瓦斯突出预警应用结果表明,电磁辐射预警技术具有较高的准确性,可以超前13 m或提前2天预警到突出危险。
According to the requirements in real-time,accuracy and convenience characteristics of pre-warning technology in coal and gas outburst,the characteristics and regularity of electromagnetic radiation in coal and rock fracture,and regularity and relativity of electromagnetic radiation and conventional indexes during coal and gas outburst evolution were analyzed.The coal and gas outburst electromagnetic radiation warning equipment and software were developed.The pre-warning criteria of coal and gas outburst forecasting with electromagnetic radiation was built.The automatic analysis and pre-warning of electromagnetic radiation in coal and gas outburst forecasting was realized. The results showed that there was high positive correlation between electromagnetic radiation and conventional indexes of coal and gas outburst,which could reflect coal and gas outburst risk.The field application of coal and gas outburst pre-warning results showed that electromagnetic radiation had high pre-warning accuracy,and could predict outburst hazard ahead 13 meters or ahead two days.
