分析了在矿井反风过程中,出现矿井风压读数减少,MCY 3型监测仪显示风量读数严重失真的具体原因,提出在风硐加装1套承压管的措施,保证监测仪在反风中的正常使用。
The paper analyzes the reason of mine wind pressure reading decrease and MCY 3 monitor shows serious distortion of air volume reading during the process of mine anti-wind, and puts forward a measure of installing one set of pressure-bearing pipe in wind tunnel to ensure that the monitor is in the anti-wind In the normal use.
