煤层电性参数测试及其与煤岩特性关系的研究

Measurement and test of seam electric parameter and study on relationship between seam electric parameter and coal petrology characteristics

试验利用实验室测试、现场实测手段, 进行了大量参数测试, 并对煤岩层电性参数进行了研究, 研究了煤的变质程度、煤岩组分、湿度、温度、频率、瓦斯压力等对电性参数的影响及各向异性问题, 并指出与电磁法勘探最密切的电性参数是煤岩层电阻率、相对介电常数和煤层对电磁波吸收系数。

The test had conducted many parameter measurements with the lab and field measuring means. The paper studied the electric parameters of coal and rock strata and studied the metamorphic grade, coal petrology contents, moisture, temperature, frequency and gas pressure of coal influenced to the electric parameters and each direction difference issues. The paper pointed out that the electric parameters close related with the mine electric magnetic exploration are the electric resistance rate of coal and rock strata, related medium and electric constants and electric magnetic wave sorption coefficient.
