Wind measuring method for complex flow field roadway

Abstract

The invention aims at proving a wind measuring method for a complex flow field roadway. A roadway wind quantity is calculated out through the measuring of the position pressure difference and the standardizing of the comprehensive wind resistance of pressure measuring positions. A first pressure measuring position and a second pressure measuring position are chosen in an area where the wind speed of a roadway which is measured is large, two pipe frames are arranged in the wall of the roadway of the first pressure measuring position and the second pressure measuring position, two pressure measuring pipes are installed on the two pipe frames respectively, the two pressure measuring pipes are connected through rubber hoses respectively, and the two rubber hoses are led to the position of a differential pressure gauge along the wall of the roadway to measure the position pressure difference. The wind measuring method for the complex flow field roadway has the advantages that the roadway wind capacity is directly measured and calculated through the measuring of the position pressure difference, so that the rapid wind measuring is achieved, the personnel interference is reduced, and the accuracy of measuring and calculating of the wind capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of downhole wind measurement, and relates to a method for measuring wind in shafts with complex flow fields. Background technique [0002] Mine air volume plays an important role in ensuring the normal work of underground personnel, preventing gas disasters such as gas, and improving working climate conditions. Sufficient air distribution is an important guarantee for mine production safety. Roadway wind measurement refers to the use of wind measuring instruments and tools to measure and calculate the air volume passing through the roadway. The "Coal Mine Safety Regulations" stipulates a strict wind measurement system, and a comprehensive wind measurement must be carried out every 10 days. For production wind locations, wind measurements should be made at any time according to actual needs, so as to grasp the distribution of mine air volume and whether it meets production requirements. The workload of mine ...
