The practical experience of experimental application in 2009 of direct-prospecting geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) (FSPEF-VERS express-technology) on the local area of coal mine in the Donbas region are given. The six anomalous geoelectric zones of gas (free methane) type were revealed and mapped on investigation area by FSPEF method survey. The bedding depths and thicknesses of the anomalous polarized layers (APL) of gas type were determined by VERS sounding. The optimal places for the degassing borehole locations were delineated on measurements data by the FSPEF-VERS methods. The experiment results testify of practical possibility of the FSPEF-VERS technology using for the free gas (methane) accumulations exploration and prospecting within the coal mines and coal-bearing series spreading, as well as they are one more weighty arguments for practicability of the more broad using of FSPEF-VERS methods in geological prospecting process for oil and gas. The application of the FSPEF-VERS technology can promote for increasing the efficiency of existing technology of the coal mine methane capturing and utilization.
