Problems solved by technology

[0002] Roadway air pressure difference is one of the important parameters of coal mine ventilation resistance. Mine ventilation resistance is an important parameter reflecting the difficulty of mine ventilation. Accurate measurement of coal mine ventilation resistance is one of the important contents of coal mine safety technology management. Therefore, roadway air pressure The difference has an important impact on coal mine safety production and economic benefits; the existing ventilation resistance measurement methods mainly use three methods: inclined differential pressure gauge method, barometer base point method and air pressure synchronization method to measure the pressure difference of underground

Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the present invention is further described:

[0031] The invention provides a method for synchronously and quickly measuring the air pressure difference in a coal mine underground roadway, which is characterized in that it comprises the following steps,

[0032] S1: Select roadway air pressure measurement routes and measuring points according to the coal mine underground ventilation system, and number each measuring point. The number is i (i=1,2,3...N, where N is the total number of measuring points );

[0033] S2: Choose two barometers, the first barometer and the second barometer, adjust the built-in clocks of the first barometer and the second barometer to the same time, and set the first barometer and the second barometer at the same time at the same position Adjust the meter to the relative air pressure measurement mode;

[0034] S3: The first surveyor carries the first barometer to the measuring point i, the second...

Abstract

The invention provides a coal mine underground roadway air pressure difference synchronous rapid determination method, which comprises the following steps: selecting a roadway air pressure measurementroute and measurement points according to a coal mine underground ventilation system, and numbering all measurement points; selecting two barometers; first measuring personnel carrying the first barometer to go to a measuring point i, and second measuring personnel carrying the second barometer to go to a measuring point i+1 from the measuring point i; measuring the air pressure value of the points after the first measuring personnel and the second measuring personnel reach the appointed measuring points; repeating the measurement until the measurement of all the measurement points is completed; and exporting measurement data of the first barometer and the second barometer, screening and marking data, and calculating to obtain an air pressure difference deltaP of adjacent measurement points in the roadway. Communication is carried out in a manner that measuring personnel drag the string, synchronous measurement of the air pressure difference of the underground roadway of the coal mineis realized, and the method has the beneficial effects of low input cost, simplicity and convenience in operation, high measuring speed and accurate measured data.
