PRINCIPLES OF MEASURING COAL THICKNESS BY RESISTIVITY METHOD ALONG A HORIZONTAL BOREHOLE AND ITS FORWARD SIMULATION

摘要: 论述了顺煤层水平钻孔中电阻率法探测煤层厚度的方法原理,使用线性数字滤波法对不同地电类型做了正演模拟。结果表明,电阻率曲线对煤厚变化反映明显,能探测厚度大于0.8m的煤层。

Abstract: The methods and principles of measuring coal thickness by resistivity method along a horizontal borehole in coal sean are presented． Several sorts of geologic-electrical models are forward simulated by using linear numerical filter． Many modelling results have showed that the resistivity curves reflect obviously the variation of coal thickness， which are enabled to measure the coal seam with the thickness mors than 0.8m．
