Method of vibration exposure tested from underground workings in the coal seam at the mine and is a new and effective way of creating new systems conductive gas cracks. The results of empirical calculations and industrial experiments confirm the possibility of applying this method for increasing the permeability of low-permeability coal. The development of the technological scheme of vibration exposure in the coal massif in the region of the resonant frequencies of the manifold for forming a gas-bearing coal formation limit destructive voltages, creating a vast and uniform zone of artificial fractures in the array and reducing its stress state and gas content is an important actual task.
