Abstract

the application of seismoacoustic profiling by the method of a common depth point (CDP) to clarify the geological conditions of the coal fields, to determine the location and extent of the existing faults is considered. The results of measurements made in the Kuznetsk Coal Basin (Kuzbass) on the basis of the use of longitudinal and shear elastic waves generated by a source of low power oscillations are presented. The field measurements have been made on the two surface geophysical profiles with the total length of 1048 m. The proposed approach allowed reaching the depth of the transverse waves distribution at the level of 300 meters and can be effectively used as complementary to other studies in determining the filtration properties and permeability of coal seams with the aim of developing measures for their degassing and subsequent utilization of coalmine methane.

Highlights

Applying of the seismological survey is an effective way to produce geological mapping, analyze the state and properties of the rocks in coal mining [1]
Despite of fact that there are some factors that complicate the interpretation of the seismic data obtained in the study of coal deposits, e.g. fairly low average thickness of coal seams in comparison with their depth, a small amplitude of the faults and the presence of the multiple interference of different nature and etc., the methods and equipment of the seismic research of coal seams is rapidly developing
This studies supplement information that can be obtained by applying injection fall-off tests [2] or determining the gas content of coal seams in desorption tests [3], to improve the efficiency of their degassing and following up utilization of coalmine methane [4-15]
