Abstract: Aiming at the technological problem of roadway wall and gas extraction borehole containing many fractures which are easily affected by mining, and the problem of leakage passage forming by fractures communication, the hole sealing method of sealing and partitioning integration by grouting in borehole and coating a layer of impervious material in the roadway of wall orifice is proposed. Fractures zone characteristics around the borehole are analyzed, the formation mechanism of ascendant air leakage passage is studied, the principle of the sealing method by sealing and partitioning integration is expounded. The borehole sealing effect of different forms insulating layer is studied by designing insulating layer's similar sealing experiment. The results shows that the sealing effect after filling insulating layer is much stronger than without filling; the greater the proportion and thickness of insulating layer, the higher the negative pressure value, the slower the decay, the better the sealing results. The sealing method of sealing and partitioning integration is applied in the Thirteenth Coal Mine of Pingdingshan Coal Industry, the test results show that sealing method of sealing and partitioning integration has excellent sealing performance which significantly increases the concentration of gas extraction.
