摘　　要：利用煤层反射波的初至特征、相位特征、振幅特征、频率特征和波组特征的变化,可以解释煤层缺失,分析煤层沉积环境,对比煤层分叉,确定构造断裂和预测煤层厚度变化趋势等。Coal layer reflection has unique features of first break,phase,amplitude and frequency and wavegroup feature. By using variation of these dynamic characteristics, we can make interpretation of coal layer pinch out, analysis of coal layer depositional environment, comparison of coal layer branch and location of structure fault and infer variation trend of coal layer thickness and so on. The practical data in the article show clearly effect in interpretating rock characteristics by using coal layer reflection feature.
