Abstract

The invention relates to mining. Method is in cyclic pumping in liquid through well drilled to layer, at that initial liquid pressure in first pump-in cycle is set as equal to value characterizing resistance of rocks to compression, in second cycle pumping in is carried out at pressure equal to vproduct of value characterizing resistance of rocks to compression by ratio of initial and end pressure in first pump-in cycle, and in each following cycle pressure is increased up to value equal to product of value characterizing resistance of rocks to compression by ratio of rate of liquid pump-in in previous and first pump-in cycle, and end pressure is installed as equal to value characterizing limit of elasticity of layer, and discharge of working liquid in each cycle is begun at pressure equal to value characterizing limit of elasticity of seam with end at pressure decrease to value larger or equal to 0.1 of hydrostatic pressure at depth of upper limit of methane zone.
