Zusammenfassung: | The invention discloses a short-distance coal seam group increasing, pumping and fixing integrated rapid outburst-eliminating coal uncovering method which comprises the following steps: S1, according to the occurrence condition of a field coal seam, reasonably designing hydraulic slotting and drilling holes, and reasonably arranging hydraulic seam pressing and drilling positions in combination with the influence range of the hydraulic slotting and drilling holes; s2, hydraulic slotting and drilling are constructed one by one according to the construction sequence; s3, hydraulic seam pressing drill holes are constructed one by one according to the construction sequence; and S4, one-by-one outburst elimination verification is performed on the coal seam in the coal uncovering area. According to the technical method, the arrangement mode that hydraulic seam cutting drilling and hydraulic seam pressing drilling are matched is utilized, the coal seam group in the coal uncovering area is disturbed through hydraulic |
