Discussions on transient Rayleigh wave exploration in coal mine

Aiming at the complex geological condition and the heavy noise in coal mine, some problems of data acquisition and procession on transient Rayleigh wave exploration are discussed. A suitable data acquisition parameter is given out on the basis of large amount of experiments. By using zero shill rectifying, digital filter and cutting, the precision and depth of transient Rayleigh wave exploration can be considerably improved.
