| 中文摘要: |
| 微地震监测技术是利用岩石破裂位置的时空分布对地下裂缝进行成像和分析,因此,震源定位是微地震资料处理中最基础和最重要的内容。本文首先介绍了微地震定位方法的研究现状,特别是近年来相对定位法在微地震定位应用中的研究进展。然后,详细阐述了两种波形叠加类相对定位方法的原理,并结合实际矿山微地震数据分析了两种方法的成像分辨率特征、计算效率和定位结果,验证了本文研究方法的可行性。最后,对波形叠加类定位方法及微地震监测技术的发展方向进行了讨论和展望。 |
| 英文摘要: |
| In microseismic monitoring, the temporal and spatial distribution of the positions of rock failures is used to image and analyze subsurface fractures. Therefore, source location is the most fundamental and most important step in microseismic data processing. In this paper, the research developments of microseismic location methods are introduced, especially recent research progress of relative methods applied in microseismic source location. Then, the principles of two waveform-based relative location methods are elaborated, and field mining-induced microseismic dataset is used to analyze their characterization of imaging resolution, computational efficiency, and location results. The field data examples demonstrate the feasibility of the studied methods. Finally, we discuss and conclude the future development of waveform-based location methods, as well as that of microseismic monitoring technology. |
