摘　　要：基于地质测井技术划分煤体结构的方法原理,对淮南潘三矿进行了测井技术的应用和验证。试验结果表明:突出煤体在测井曲线上具有视电阻率高、自然电位正异常、自然伽玛小、人工伽玛大、井径大、声波时差高等特点,在地质上分为面状、带状和线状3种分布方式,通过地质测井技术可划分煤体结构,进而预测煤层瓦斯突出。The geological logging technology was applied to study the coal mass structure divided method principle. The application and verification of the logging technology were conducted in Panji No. 3 Mine of Huainan. The test results showed that the outburst coal mass would have a high visual electric resistance in the logging curve, natural electric potential abnormal, natural gamma small, artificial gam- ma Large, large borehole diameter, sonic wave time difference high and others. The outburst coal would have three distribution modes, as a flat, belt and line in geology. With the geological logging technology, the coal mass structure could be divided and thus the seam gas outburst could be predicted.
