基于高分辨率三维地震的地质构造勘探研究与应用

Research and Application of Geological Structure Exploration Based on High-resolution 3D Seismic Data

针对传统地质勘探技术分辨率低、方法局限、难以有效揭示复杂地质构造,进而影响煤层开采安全的问题,本研究基于高分辨率三维地震技术,对小纪汗煤矿11、13盘区进行了勘探。首先划分了勘探区域,并介绍了技术应用方法。随后,利用高分辨率反演技术和精细的解释流程,对2煤层的主要地质构造进行了精确定位。结果揭示了区内地质构造形态、煤层厚度变化、煤层分叉条带及冲刷薄弱带等关键地质信息。本研究为煤矿安全生产与高效开采提供了重要基础数据,验证了三维地震技术在复杂地质条件下的应用价值。

In response to the low resolution and limited methods of traditional geological exploration techniques,which make it difficult to effectively reveal complex geological structures and thus affect the safety of coal seam mining,this study explored the 11th and 13th panels of Xiaojihan Coal Mine based on high-resolution 3D seismic technology.Firstly,the exploration area was divided and the technical application methods were introduced.Subsequently,the main geological structures of the 2nd coal seam were accurately located using high-resolution inversion techniques and refined interpretation processes.The results revealed key geological information such as the geological structure morphology,changes in coal seam thickness,coal seam branching zones,and weak erosion zones within the area.This study provides important basic data for coal mine safety production and efficient mining,and verifies the application value of 3D seismic technology in complex geological conditions.
