A single-point measurement and control device and method for average wind speed in mine roadway

Abstract

The embodiment of the present invention discloses a single-point measurement and control device and method for the average wind speed of a mine roadway, including: determining a measurement and control point in the roadway, and constructing a wind speed measurement system at the measurement and control point; setting the front and rear areas of the measurement and control point as measurement and control points Area, judge whether the current state of the measurement and control area is suitable for wind speed measurement; according to the judgment result, run the wind speed measurement system to measure the wind speed at a single point, which can avoid the influence of mining operations and roadway traffic on the wind speed measurement, and ensure the measured average wind speed It is not interfered by temporary factors, and the detection accuracy is improved; the single-point wind speed measurement result is converted into the average wind speed; the measured average wind speed is compared with the average wind speed set by the system, and if the average wind speed is within the allowable range, the fan will not Adjust the wind speed. If it is not within the allowable range of the average wind speed, the adjustment signal will be transmitted to the fan control system, and the fan can be adjusted according to the wind speed in the roadway to control the wind speed in the roadway to meet the production needs.

Description

technical field [0001] The embodiment of the invention belongs to the technical field of mine ventilation, and specifically relates to a single-point measurement and control device and method for the average wind speed of a mine roadway. Background technique [0002] Mine ventilation is an important part of mining operations. The measurement of the average wind speed in the tunnel is the basis for ensuring the reliable operation of the mine ventilation system and an important work content of mine ventilation management; by measuring the average wind speed, the ventilation status in the tunnel can be grasped in a timely and effective manner; The accuracy and real-time performance of average wind speed measurement has important practical significance for mine safety. [0003] The traditional roadway wind speed measurement often adopts the line method (that is, the wind meter is used to move at a constant speed on the roadway section according to a certain line, and the average...
