| description | The utility model relates to the technical field of underground coal mine pressure reduction, in particular to an underground coal mine high confined water drilling pressure reduction device which comprises a plurality of pipeline bodies, one end of each pipeline body is fixedly connected with a first ring opening, and the diameter of each first ring opening is larger than that of each pipeline body. A second ring opening is fixedly connected to the position, close to the interior of the first ring opening, of one end of the pipeline body, and a cavity is formed between the first ring opening and the second ring opening. The utility model has the advantages that a matched cavity can be provided through the first ring opening and the second ring opening, the third ring opening extends into the cavity, the first fixing ring is attached to the second fixing ring at the moment, the plurality of clamping blocks are respectively clamped with the plurality of clamping grooves, the torsion resistance between devices |
