摘要
三维地震勘探相关技术随着近年来的快速发展,取得了比较丰富的成果。利用三维地震勘探技术在解释地下煤层赋存形态及其构造方面具有较为明显的优势,尤其是在解释地质异常区以及圈定其范围方面取得较好的效果。本文通过地震时间剖面上不同的特征表现,对采空区、陷落柱、煤层露头、岩浆岩侵入、火烧区、煤层冲刷带以及煤层分叉等较为常见的地质异常体进行解释、圈定,得到比较理想的地质成果。
With the rapid development of three-dimensional(3D)seismic exploration technology in recent years,its application has demonstrated significant advantages in interpreting the form and structure of underground coal seams,particularly in identifying geological anomalies and delineating their extent.Common geological anomalies such as goafs,collapse columns,coal seam outcrops,magmatic rock intrusions,fire zones,coal seam scouring zones,and coal seam bifurcations were identified through the distinct characteristics observed in seismic time sections,yielding highly accurate geological interpretations.
