For hydraulic fracturing in the deep geological conditions, crack closure, the present situation of the extraction effect is poor, developed including mixed bone bunker and together with bin, hydraulic fracturing and aggregate equipment, formed the construction technological process, in a typical low permeability coal seam pan three mine of huainan mining area for the practical application, has made significant technical effect: after fracturing of coal seam permeability coefficient increased by 13.31 times, anti-reflection regional standard extraction time is not anti-reflection reduce 26d.
