基于层析成像技术的煤矿槽波地震勘探研究

Study on seismic exploration of coal mine trench wave based on tomography

为了精确有效地对煤矿进行超前地质勘探,确保煤矿安全生产,采用层析成像技术对煤矿进行地质勘探。分析研究了槽波层析成像反演算法、不同炮点实测槽波信号、槽波数据处理信号以及不同频率下层析成像结果等。研究表明:当选择了3个频率拾取旅行,频率在100 Hz时,对应的结果最符合要求,可以明显看出有3个高速异常区域,结合已经揭露的地质构造进行分析,与实际地质构造相吻合。

In order to accurately and effectively carry out advanced geological exploration of coal mines to ensure the safe production of coal mines,the use of tomography technology for geological exploration of coal mines. The slot wave tomography inversion algorithm,the different shot point measured trough wave signal,the trough wave data processing signal and the different frequency tomography results were analyzed. Study found that when the three frequency picking travels are selected,the corresponding results are most suitable at 100 Hz,and it is obvious that there were three high-speed anomaly areas,which were combined with the exposed geological structure Geological structure consistent. The study provides reference significance for trench wave seismic exploration under similar engineering geological conditions.
