Description
Technical Field
The invention relates to the technical field of gas control, in particular to a rapid plugging device for a reserved pipe for gas control.
Background
During underground coal mining, gas is generated along with the mining of the coal. The hidden danger of gas on the coal face is mainly at the upper corner, and a three-way pipe is arranged on the reserved pipe at certain intervals and used for extracting the gas at the upper corner of the coal face. When the coal face is mined to the position of the three-way pipe, the blocking plate of the three-way pipe is opened. Because the three-way pipe in the goaf continuously pumps air, an air flowing area is formed between the air conveyed by the conveying roadway and each three-way pipe in the goaf. The residual float coal in the goaf is accelerated to be oxidized along with the increase of air, and further spontaneous combustion occurs. In order to reduce the spontaneous combustion risk of the goaf, the reserved pipe of the goaf needs to be disconnected along with the advance of the coal face, and gas at the upper corner of the coal face cannot be normally extracted in the period of disconnecting the reserved pipe, so that the gas at the upper corner of the coal face is accumulated.
