Abstract
The conditions that must be taken into account when developing equipment for interval fracturing of a coal seam are investigated. The expediency of providing the packer with a profiled blade for passing clogged well sections is determined. The use of experimental equipment increased the methane yield from the well by a factor of 2.5.
