Abstract: Rayleigh wave detection as a shallow seismic detection method, characterized by advantenges of being simple and convenient, has been applied in many fields.The paper analyzes the factors affecting the precision of Rayleigh wave exploration in coal mine and gives construction technology, setting parameters and problem to pay attention to.According to actual situation, channel interval, offset, sampling rate, magnification, hammer-blow times, seismic line layout and reliable collection window were determined.
