基于槽波层析成像的陷落柱定位研究
|
摘要
在煤矿井下地震勘探中,由于检波器和震源只能在巷道内进行布置,造成了观测系统的布局和分布特点受到限制。为了更好地探测煤矿进行实际异常的地质构造,确保矿井安全生产,采用槽波层析成像的方法对陷落柱定位进行研究。研究了陷落柱对煤层波场的影响,得出陷落柱对体波成分影响相对较小,而对瑞雷型槽波Rx和Rz分量的影响却相对较大;又对陷落柱速度成像和陷落柱能量成像进行了研究,研究验证了槽波层析成像技术在陷落柱分布范围定位中的准确性,研究为煤矿井下陷落柱地质构造的勘探提供了技术支持。
In the coal mine seismic exploration,the geophones and sources can only be arranged in the roadway,resulting in the limitation of the layout and distribution of the observation system. In order to better detect the actual abnormal geological structure of the coal mine and ensure the mine safety production,Slotted wave tomography was used to study the positioning of the collapse column. The influence of the collapse column on the wave field of the coalbed was studied. The results showed that the collapse column has a relatively small influence on the body wave component. However,the Rx and Rz components,but also relatively large; and the collapse of the column velocity imaging and energy imaging of the collapse of the study to verify the slot wave tomography accuracy of the positioning of the collapse of the column,the study for the construction of coal mine collapsed column geological exploration provided technical support.
