摘　　要：针对矿井中电磁干扰强烈、环境复杂、杂散电流较难准确采集等特点,提出了一种改进小波阈值的矿井杂散电流检测方法,并运用实于际检测中。结果表明,该检测方法能很好的滤除矿井中高频噪声信号,实现杂散电流的准确检测,为矿井安全运行提供保障。In view of the features in coal mine such as the strong electromagnetic interference,the complex environment,and the stray current is difficult to accurately collected,etc.,a kind of improved stray current detection method based on the wavelet threshold is proposed in this paper,and then it is used in practical tests. The results show that the detection method can better filter out the high frequency noise signal in mine,thus to realize the accurate detection of stray current,and guarantee safe operation for the mine.
