摘    要：瓦斯突出煤体是在瓦斯突出灾害发生前就已经客观存在的地质体，是发生瓦斯突出的必要的物质条件.针对瓦斯突出煤体煤样的特点，采用具有国际先进水平的数字式双频激电仪作为主要观测仪表，建立了集先进性和实用性为一体的瓦斯突出煤体电性参数观测系统.通过进行实验室大量煤样的测定，研究了瓦斯突出煤体的导电性质.为利用以电磁法为主的地球物理方法进行瓦斯突出煤体探测和瓦斯突出预测提供了物理基础.对减轻和防止煤矿瓦斯突出自然灾害具有重要意义.

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.
