Methods seam gas pumping rate of increase electromagnetic pulse

The present invention discloses a method of pulsed electromagnetic seam gas pumping rate increases, the role of the coal body by electromagnetic pulse testing laboratories, to give the desired final field intensity of electromagnetic waves and a frequency parameter, and then, connected to the electrode plates into the feeder the gas drainage borehole casing, to form a high-intensity pulsed electromagnetic waves in the electrode plates by a pulsed electromagnetic field generating apparatus, the electromagnetic waves to complete the seam. A way simple, easy to use, flexible, wide scope, subject to the roadway or surface environment less impact, after the effect of coal seam permeability significant improvement for coal seam gas drainage has created favorable conditions.
