FIELD: mining.
SUBSTANCE: method includes the stimulation of reservoir fluid and rock by the pressure of accumulated gaseous products of solid fuel burning. Gases are accumulated in two gas-accumulating sections, the internal volume of each of them is equal from 10 to 18 l, at combustion at least in one of sections of solid fuel charge weighing 6 kg minimum, with increased gas generation from 1100 l/kg. Gases are discharged through gas-distributing section, in one or several stages, evenly along the whole width of the processed layer interval. For discharge of gases at the pre-set pressure the burst dome-shaped diaphragms made of thin-sheet roll are used, providing dispersion of operation pressure no more than 5%.
EFFECT: improvement of efficiency and safety of fracturing technology.
