Description

Technical Field

[0001] The utility model belongs to the technical field of mine plugging, and in particular relates to a novel mine plugging blasthole device. Background Art

[0002] The blasthole sealing device refers to the sealing device for the coalbed methane extraction and coalbed water injection drilling holes, which mainly include gas extraction hole sealers and coalbed water injection hole sealers.

[0003] The current plugging devices on the market have the following problems when used:

[0004] 1. When a traditional plugging device needs to be installed in a hole, it is usually directly inserted into the hole. The airbag bag on the side of the plugging device is relatively fragile. When the airbag bag is inserted, the side of the airbag bag is generally damaged by friction and compression, and the protective performance is poor.

[0005] 2. When the traditional plugging device is in use, it needs to be used in conjunction with a connecting pipe, through which gas or plugging material is transported. During the injection, the connection between the plugging device and the connecting pipe is prone to leakage, and its sealing performance is poor. Utility Model Content
