Seismic monitoring technology of driving and detection integrated of coal mine roadway

Abstract Hidden geological features, such as water and gas, cause frequent accidents during coal mine roadway driving. Seismic monitoring technology of driving and detection integrated presents distinct advantages and is a geological guarantee technology urgently needed for intelligent driving of roadways. The success of this technology hinges on the high-resolution signals impulse processing and high-precision imaging. This article employs a seismic while driving field test during coal roadway driving to validate the efficacy of the proposed impulse algorithm and its full waveform inversion method. The inversion results demonstrate that these methods effectively process seismic signals while driving. With a limited detection signals, the distribution characteristics of rock properties in front of the driving can be reliably inverted, enabling the precise identification of abnormal structures. This capability furnishes valuable geological information for roadway driving, thereby enhancing construction safety.
