The approach to determine the length of degasification boreholes by profilometry using echolocation method in mine conditions is substantiated. The results of cameral processing of echograms obtained in field studies are presented. The relationship between the effective length of boreholes and their methane content has been established. The bearing pressure zone influence of on physical condition of horizontal boreholes drilled to undertake strata degasification is shown.
