Study and practice of disconnect-type sealing technology for seam-crossing drilling drainage
BAI Ming-kai
Abstract：In order to ensure the drainage effect and achieve the purpose of saving material, the borehole imaging ZKXG30 mine track detection device for internal characteristics of rock layer drilling peeping was applied, which found that, above the borehole, most fissures did not develop in spite of small range rock fissures. According to the development situation in drilling hole of rock fracture, the sealing method was improved and the metal push rod and the sealing tube fixing device were developed, and a new sealing technology was developed undeveloped rock fissures instead of sealing tube. The sealing effect was compared with the whole sealing tube, the new sealing technology showed good air tightness, no leakage, after a month drainage statistics, production parameters consistent with two kinds of drainage borehole sealing technology, the technology can be widely used under similar gas geological conditions.
