[0003] At present, the method of measuring the air volume of underground roadways is generally to use the wind meter to measure the wind speed at multiple positions in the roadway section, and use the average value of the measured multiple wind speeds to replace the average wind speed through the roadway, and then combined with the area of the roadway to obtain the passage The air volume of the roadway, the above process is generally carried out manually, because the selected wind measurement points are limited, and people will disturb the state of the wind flow in the roadway, and the error of the manual measurement itself leads to a large error in the final measured air volume
Therefore, the current air volume measurement method cannot meet the industrial needs of mine intelligent ventilation, and it is difficult to realize real-time and accurate monitoring of air volume

The invention discloses a system and method for measuring air volume at the full section of a roadway, comprising air volume measuring device I and air volume measuring device II, where air volume measuring device I is slidably arranged on track I, and air flow measuring device II is slidably arranged on track II; The linear wind speed at each horizontal height of the roadway section and the distance between the two walls of the roadway can be obtained by using infrared ranging and related calculation methods, and then the roadway section is divided into multiple small rectangular units by using the calculus principle, and then each small rectangular unit passes through The air volume of each small rectangular unit can be integrated to obtain the air volume passing through the entire roadway, and at the same time, the area of the roadway section and the average wind speed can be obtained. Therefore, the present invention avoids errors caused by manual measurement, so that the air volume passing through the trapezoidal or rectangular roadway can be accurately monitored in real time, and at the same time, the area of the roadway section and the average wind speed passing through the section can be accurately measured.
Description
technical field [0001] The invention relates to a system and method for measuring the air volume of a full section of a roadway, and belongs to the technical field of roadway wind speed monitoring. Background technique [0002] Energy is an important guarantee for the development of modern society. Coal still accounts for the largest proportion of my country's primary energy consumption. With the deepening of coal seam mining, the occurrence and mining conditions of underground coal seams are becoming more and more complex, and various natural disasters occur frequently, especially It is coal mine gas, fire, dust and other disasters. Reasonable and effective ventilation can greatly reduce or even eliminate these disasters. The necessary condition for achieving the best ventilation effect is real-time and accurate monitoring of mine ventilation. Only by mastering the accurate air volume and wind speed information in the shaft can the next control operation of the ventilation s...
