Abstract

Summary

To aid in coal seam faults exploration in the underground coal mines, a seismic location method based on multidirectional summation of reflected seam waves was developed. In contrast to the known method of controlled directional reception (CDR), it is proposed to calculate the time shifts between seismic records using not only the linear component of the hodograph of the reflected waves with a common source (or receiver) point, but also a hyperbolic component. The asymmetry of this hodograph, as well as the specifics of the placement of the seismic observation system in the mine workings, allow for a separate detection of the reflecting boundaries in the four sectors of the outer (relative to the observation system) part of the coal seam. The proposed method can be useful when a single mine working is utilized.
