| Abstract: | The outburst coal mass is a geologic body which had objectively existed before outburst disaster occurred and is a substantial prerequiste to outbursts. In this paper an advanced and practical surveying system for measuring the electrical properties of the outburst coal has been built mainly by means of digital dual frequency IP instrument which is in advanced position in the world. The authors studied the electrical properties of the outburst coal according to measurement results from a large number of specimens in laboratory. The paper provides the physical basis for probing the outburst coal mass and predicting outbursts mainly by electromagnetic method and other geophysical methods. It is of very important significance to alleviating and preventing the natural disaster caused by outbursts in coal mines. |
