The invention discloses an underground gas extraction pipeline connection drainage comprehensive facility device, and belongs to the technical field of coal mine underground pipeline systems. The device comprises a main pipeline; a pumping support pipe communicating with the main pipeline is arranged on the main pipeline; the other end of the pumping support pipe communicates with a flow separation box; the flow separation box is provided with a pumping device and a flow separation drainage port communicating with the flow separation box; the main pipeline is provided with two drainage supportpipes communicating with the main pipeline; the other ends of the drainage support pipes communicate with a drainage pipe through a connecting pipe; a water outlet valve is arranged on the drainage pipe; a first valve is arranged on the connecting pipe; and the drainage support pipes, the connecting pipe and the drainage pipe are all arranged right under the main pipeline. The device solves the problems of low working efficiency in the gas extracting process, easy extraction of a lot of water, complex operation of a drainage device and incapability of draining water in the gas extracting process by using a present pipeline system.
Description
technical field [0001] The invention relates to the technical field of underground pipeline systems in coal mines, in particular to an underground gas drainage pipeline-connected pipe drainage comprehensive facility device. Background technique [0002] When working underground in coal mines, gas drainage is an important operation to ensure safe production. In the past, when underground gas was drained, it was often done by installing a split exhaust pipe on the main drainage line and using a drainage pump. However, since the pipe diameter of the diversion exhaust pipe on the main road is generally only one inch, and it is difficult to arrange the diversion exhaust pipes in a centralized manner in order to ensure the structural rigidity of the main pipe, this method mainly exists in the main pipe. Gas drainage at a single position has a small amount of drainage, low work efficiency, and is easy to bring out water during the process of gas drainage; The water discharge devic...
