【摘要】：為了實現(xiàn)煤巖物質(zhì)組成和結(jié)構(gòu)的高效電法勘探,基于巖石頻率域激電效應(yīng),采用復(fù)電阻率法測試對四種不同變質(zhì)程度的原生結(jié)構(gòu)煤在不同方向上的復(fù)電阻率模值頻率響應(yīng)特征進(jìn)行了研究。研究結(jié)果表明:隨著頻率不斷增加,不同變質(zhì)程度煤復(fù)電阻率模值在走向、傾向、垂向上均依次呈遞減趨勢;低頻階段復(fù)電阻率模值呈現(xiàn)明顯各向異性;高頻階段復(fù)電阻率模在水平向和垂向呈各向異性,走向和傾向呈各向同性,造成這樣的原因與煤中可極化電介質(zhì)極化的時間長短有關(guān)。
[Abstract]:In order to realize the high efficiency electrical prospecting of the composition and structure of coal and rock materials, based on the rock frequency domain induced electricity effect, The frequency response characteristics of four primary structural coals with different metamorphism in different directions were studied by using complex resistivity method. The results show that: with the increasing of frequency, the modulus value of complex resistivity of coal with different metamorphic degree shows a decreasing trend in order of strike, tendency and vertical direction, and the modulus value of complex resistivity shows obvious anisotropy at low frequency stage. At the high frequency stage, the complex resistivity modes are anisotropic in horizontal and vertical directions, isotropic in strike and tendency, which is related to the time of polarization of polarizable dielectric in coal.
