摘要
煤层厚度的变化是煤炭开采过程中最常见的地质现象,如果煤层厚度预测误差过大,必将给煤矿生产产量和安全带来很大的影响。目前,三维地震勘探成果对煤层厚度的预测是一种比较有效的方法,它主要是分析煤层反射波的地震属性随煤层厚度变化的规律,进而依据这种规律对煤层的厚度进行预测。本文在介绍、归纳地质统计煤厚预测方法的基础上,将这种预测方法应用在三维地震勘探解释过程中,通过实际对比、分析取得了令人满意的成果。
        The change of coal seam thickness is the most common geological phenomenon in coal mining process.If the prediction error of coal seam thickness is too large,it will have a great impact on coal mine production and safety.At present,the prediction of coal seam thickness by 3D seismic exploration results is a relatively effective method.It mainly analyzes the variation of seismic properties of coal seam reflection waves with coal seam thickness,and then predicts the thickness of coal seam according to this law.On the basis of introducing and summarizing the geostatistical coal thickness prediction method,this prediction method is applied to the 3D seismic exploration and interpretation process,and satisfactory results have been obtained through actual comparison and analysis.
