Problems solved by technology
At present, the gas monitoring in the return airway of the coal mine mainly detects the concentration of this part of the gas, and its purpose is mainly to serve the mine ventilation and coal mine safety, while the monitoring of the gas emission in the return airway is less, and there is a lack of necessary monitoring means and methods
On the other hand, the monitoring of carbon dioxide and carbon monoxide emissions in the air return lane is basically in a blank state

The invention relates to a method for monitoring gas emission of a return airway. The method comprises the following steps that S1, two arched tracks which are crossed with each other are mounted in the return airway; S2, a pair of wind speed sensors are mounted on the two arched tracks, and a methane concentration sensor and a multi-parameter sensor are respectively mounted; S3, the wind speed is monitored in real time through two wind speed sensors, and the average wind speed is calculated; S4, the methane concentration, the carbon monoxide concentration and the carbon dioxide concentration in the return airway are monitored through the pair of methane concentration sensors and the pair of multi-parameter sensors on the two tracks; S5, receiving the average wind speed, the methane concentration, the carbon monoxide concentration and the carbon dioxide concentration through a return airway gas emission monitor; and S6, a return airway gas emission monitor calculates the real-time gas emission amount, the carbon monoxide emission amount, the carbon dioxide emission amount and the accumulated emission amount of the return airway according to the received data.
Description
technical field [0001] The invention belongs to the technical field of coal mining safety, and relates to a method for monitoring gas discharge in return air lanes. Background technique [0002] Climate change caused by greenhouse gas emissions is a common challenge faced by all mankind. Coal mine gas is a strong greenhouse gas, and the greenhouse effect of methane in coal mine gas is 21 times that of carbon dioxide. Due to the low concentration of exhaust gas in the air return lane, it is difficult to use this part of gas for incineration and power generation, and its use value is low. Therefore, most coal mines discharge exhaust gas directly into the atmosphere. [0003] Accurate measurement of gas and other greenhouse gas emissions in the return airway is the basis and core of strengthening emission management. At present, the gas monitoring in the return airway of the coal mine mainly detects the concentration of this part of the gas, and its purpose is mainly to serv...
