地震勘探技术在解释地质异常体的应用分析

地震勘探技术在控制煤层赋存形态方面有高于其它物探方法的优势,尤其在准确圈定小窑采空区、岩浆岩侵蚀、煤层露头、火烧区及冲刷带、陷落柱等地质异常体方面已取得了很好的效果,对煤矿产业的生产和建设都起到了举足轻重的作用。本文通过河北、新疆和山西等地煤矿采区三维地震勘探实例介绍了如何根据地震时间剖面表现的不同特征来确定和解释各种煤层地质异常体,并取得了良好的地质成果。

The Application of Seismic Exploration Technology to Geological Anomalous Body Interpretation

Seismic exploration technology has an advantage over other geophysical methods in control of coal seam occurrence form,especially in accurately determining geological anomalous bodies of gob area,magmatic rock intrusion,combustion area and erosion zones,coal seam outcrop and so on,good effects are obtained,for it plays a decisive role in the production and construction of the coal industry.Taking the 3Dseismic prospecting of the coal mining areas in Hebei,Xinjiang and Shanxi as examples,this paper introduced how to identify and interpret the various geological anomalous body according to the different characteristics of seismic time section.And finally it gained a good geological achievement.
