摘　　要：为了在金佳矿建立煤与瓦斯突出区域—局部动态实时监测预警系统,基于KJ838声电瓦斯系统,对11224运输巷工作面掘进周期内声发射与电磁辐射的噪声扰动进行了分析。结果表明:KJ838声电瓦斯系统能及时对巷道中的环境变化进行响应,放炮、开溜槽、开铲车等工序均会对声—电信号造成特定扰动。In order to establish the coal and gas outburst real-time on-line early-warning system in Jinjia Mine,the noise disturbance of acoustic emission and electromagnetic radiation during the driving cycle of 11224 roadway was analyzed based on KJ838 acoustic electricity gas system. The results showed that the KJ838 electro-acoustic gas system can respond to the environmental changes in the roadway in time,blasting,pan opening and opening of forklifts and some technics can cause certain disturbance to the electro-acoustic signals.
