| description | The invention discloses sealing and leakage blocking equipment for gas extraction, and relates to the technical field of gas extraction, the sealing and leakage blocking equipment comprises a horizontal well arranged in a rock stratum and located above a coal seam; the vertical well is vertically formed in the rock stratum and communicates with the horizontal well; the extraction equipment is fixedly mounted at the outlet of the vertical well and is used for extracting gas in the well; the sealing assembly is fixed at the outlet ends of the horizontal well and the vertical well; and the plugging assembly is mounted on the outer wall of the sealing assembly and used for extracting gas leaked due to the cracked slurry. The horizontal well and the vertical well can be sealed through the sealing assembly, gas leakage is avoided, gas leaked due to slurry cracking can be extracted through the plugging assembly, and the safety of gas extraction is improved.
