| 摘 要： | 煤层厚度预测的传统方法是利用钻孔资料的内插对比获得,精度很低。在实际应用中,人们又研究出了多种方法。这里从薄层理论出发,对这些方法进行了研究归纳,采用钻孔约束频域定量预测法(谱矩法)来编制相应的程序进行煤层厚度定量预测,并对影响煤厚变化的因素进行分析,得出了有用的结论。通过理论模型和实际资料运用,证明该方法预测精度较高,可取得令人满意的效果。

| Abstract: | The traditional method of coal-layer thickness prediction is to interpolate and contrast between the boreholes,of which precision is very low and thus many new methods are proposed for practical applications.In this paper,started with the thin-layer theory,these methods are evaluated,then quantitative prediction method in frequency domain restricted by borehole(amplitude-moment method) is adopted and relevant program is compiled to predict the coal-layer thickness quantitatively,and those factors that affected the coal-layer thickness are analyzed.With application of theoretical models and practical data,it is proved that this method is high-precision and achieve a satisfactory result. |
