Abstract

The invention discloses a gas continuous releasing device and a coal mine air leakage volume detection method using the same, and relates to the technical field of coal mine mining. A gas storage cylinder for storing sulfur hexafluoride gas is arranged in a box body; the air outlet end of the gas storage cylinder communicates with an air delivery pipe; the tail end of the air delivery pipe is connected with an inlet section of a decompression device; an outlet section of the decompression device communicates with the air inlet end of a pressure stabilizing valve; the air inlet end of the pressure stabilizing valve communicates with the air inlet end of a flow measuring device; the air outlet end of the flow measuring device is connected with an air outlet pipe; the air outlet pipe extendsout of the box body; and a drying oven with a desiccant is also arranged in the box body. The air leakage condition of a working face can be found in time, the basis is provided for coal mine ventilation control technicians to manage the air volume of the working face, reduce the air leakage of the working face, and prevent coal spontaneous combustion and gas accumulation, the technical guaranteeis provided for the safe production of a coal mine, the hidden danger of spontaneous combustion during the mining of the working face can be eliminated, and the safe and smooth mining of the working face is ensured.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a continuous gas release device and a coal mine air leakage air volume detection method using the device. Background technique [0002] The air leakage of the coal mine mining face refers to the air volume directly flowing into the return air channel through the air leakage channels such as gobs, ventilation structures and coal rock pillar cracks without personnel working in the stope space of the working face. Accidents such as insufficient air volume, spontaneous combustion of leftover coal in gobs, etc. Accurately measure underground air leakage, grasp the air leakage volume and air leakage rate of the working face, improve the effective air volume rate, and avoid various accidents caused by air leakage. The air leakage in the coal mine working face mainly includes two parts, one part is the air leakage along the inside of the mining face (referred to as the internal...
