Near-Field Microseismic Data Processing in Deep Tunnels
Description
This book focuses on research into near-field microseismic monitoring technology for deep-buried engineering. It proposes a series of innovative methods for microseismic data analysis, including signal identification, P/S arrival picking, coda wave-based event cluster localization, localization of heterogeneous microseismic events, surrounding rock stability analysis of cross tunnel, and double-difference dynamic tomography. The book serves as a reference for researchers in the field of microseismic monitoring and provides technical support for rockburst early warning in deep-buried engineering. Its main features and benefits include:
(1) The proposed methods exhibit stronger adaptability to complex environments.
(2) The series of analytical methods consider the interconnections between microseismic events, better reflecting the collective characteristics of microseismic activity.
(3) The series of methods proposed in this book fully account for the heterogeneity of the surrounding rock.
