Problems solved by technology

[0006] The purpose of this invention is to solve the existing and unsolvable problems in the above-mentioned prior art based on the application method of water-gas vortex fluid to control the gas in the upper corner of the coal mine, thereby disclosing a method that completely separates the two physical properties of the liquid phase and the gas phase. Different fluids are mixed to form a multiphase water-gas vortex fluid, which fills the upper corner of the coal mine, and through continuous vortex flow, the gas in the upper corner of the coal mine overflows into the main air flow for dilution and discharge, or with The liquid particles are combined and discharged together with the coal mine minerals or other liquid solids; and the vortex fluid flow fills the upper corner of the coal mine so that no gas accumulation can occur in this space. The technical scheme of the device and application method, the technical scheme is simple, reliable, It is easy to operate, timely, reliable, thorough, efficient, and does not cause secondary pollution. The water-gas vortex fluid control gas device in the upper corner of the coal mine, so as to avoid the occurrence of vicious incidents caused by the out-of-control gas in the upper corner

Embodiment approach 1

[0021] A device for controlling gas in upper corners of coal mines based on water-air vortex fluid, the device is composed of a pressure water circuit 1, a pressure gas circuit 2, an intelligent controller 3, a gas-water vortex generating device 4, a fixed pillar 5, and an air flow guide overflow fold Flow plate 6, upper corner 7, goaf 8, working face coal wall 9, coal mining face 10, main airflow 11, top plate 12 and bottom plate 13, pressure water channel 1 and pressure gas channel 2 are used for gas-water atomization The power source of the device, their working pressure range is 0.6Mpa, and the dosage volume ratio is 1:0.05. The air-water vortex generating device 4 is respectively connected to the pressure water circuit 1 and the pressure gas circuit 2 through the intelligent controller 3, and is supported by a fixed pillar 5 Between the top plate 12 and the bottom plate 13, the fixed pillar 5 is arranged separately, the fixed pillar 5 is arranged in the upper area of ​​the...

Embodiment approach 2

[0030] The working pressure is 0.2Mpa, the dosage volume ratio is 1:0.001, the fixed pillar 5 is arranged separately, and the air-water vortex generating device 4 is fixed on the upper part of the fixed pillar 5 close to the upper corner 7, so that it is inclined upward at an angle of 30 degrees. The air-water atomized vortex fluid is sprayed toward the position of the top plate 12, and the fixed pillar 5 is arranged in the middle of the upper corner 7, and the others are the same as in the first embodiment.

Embodiment approach 3

[0032] The working pressure is 0.5Mpa, the dosage volume ratio is 1:0.03, the fixed pillar 5 is arranged separately, and the air-water vortex generator 4 is fixed on the upper part of the fixed pillar 5 close to the upper corner 7, so that it is inclined at an upward angle of 35 degrees. Direction sprays air-water atomized vortex fluid to the position of the top plate 12, the fixed pillar 5 is arranged at the lower part of the upper corner 7, and the others are the same as the first embodiment.

Abstract

The invention discloses an application method for treating gas in an upper corner of a coal mine based on a water vapor vortex fluid, and belongs to the technical field of fluid application. The application method is characterized in that two fluids with distinct physical properties in liquid phase and gas phase are mixed to form a multi-phase flow water vapor vortex fluid, the upper corner of thecoal mine is filled with the fluid, the gas in the upper corner of the coal mine is overflowed into a main airflow through continuous vortex flow to be diluted and discharged, or the gas is combinedwith liquid particles to be discharged along with mineral or other liquid solids of the coal mine; and the upper corner of the coal mine is filled with the vortex fluid so that no gas accumulation canoccur in the upper corner. According to the application method for treating the gas in the upper corner of the coal mine based on the water vapor vortex fluid, the occurrence of vicious events causedby the out of control of the gas of the upper corner is avoided, and the application prospects are wide and the significance is very significant. The application method for treating the gas in the upper corner of the coal mine based on the water vapor vortex fluid is simple, reliable, easy to operate, timely, thorough and efficient, and does not cause secondary pollution.

Description

technical field [0001] The invention relates to an application method for controlling gas in the upper corner of a coal mine based on a water-air vortex fluid, which belongs to the field of fluid application technology, and is specifically a method of mixing two fluids with completely different physical properties in a liquid phase and a gas phase to form a The multi-phase water-air vortex fluid makes the fluid fill the upper corner of the coal mine, and through the continuous vortex flow, the gas in the upper corner of the coal mine overflows into the main air flow for dilution and discharge, or combines with liquid particles to accompany the coal mine minerals or Other liquids and solids are discharged together; and the vortex fluid flow fills the upper corner of the coal mine so that no gas accumulation can occur in this space. Background technique [0002] Gas refers to the harmful gas mainly consisting of methane in mines, sometimes methane alone. Gas is a colorless, t...
