Abstract

The invention discloses a gentle wind speed measurement device and method for a coal mine tunnel, and the device mainly consists of an arc-shaped graduated scale, a light large-section ball, and a hauling rope. One end of the hauling rope is fixed at a top supporting point, and the other end of the hauling rope is used for hauling the light large-section ball. The light large-section ball can swing upwards through a certain angle under the action of gentle wind in the coal mine tunnel. The higher the wind speed is, the larger the swinging angle is. The arc-shaped graduated scale is used for measuring the swinging angle, and a corresponding wind size is marked on the graduated scale. The device is simple in structure, is low in cost, is portable, can measure the speed of gentle wind effectively and quickly, and facilitates the adjustment and management of a wind network of a coal mine.

Description

technical field

[0001] The invention relates to a device and method for measuring micro wind speed, in particular to a device and method for measuring micro wind speed in coal mine roadways which play an important role in coal mine safety management. Background technique

[0002] Coal mine ventilation system is a complete system consisting of ventilation network, ventilation power and ventilation control facilities. Its main purpose is to provide sufficient fresh air to the working area of ​​the coal mine and discharge dirty air in time. The complete flow route of the air flow in the ventilation system is very important to the safe production of coal mines. The air flow enters the mine from the air inlet shaft, passes through the underground operating sites, and then enters the return air shaft, and finally exits the mine from the return air shaft. During the production period, the ventilation system is mainly to drive the ventilation power in the most economical way, to pro...
