一、概述及主要技术指标近年来随着科学技术的发展,我国煤炭工业发生了很大的变化,正在用各种先进技术装备武装煤矿,但是由于井下作业环境恶劣,瓦斯、粉尘、水、火等各种自然灾害仍然威胁着矿井的安全,因此我国十分重视矿井安全参数的自动化检测。在矿井自动化检测中,风速、风量是井下重要的安全参数之一。风不但能够给矿井
I. Overview and Main Technical Indexes In recent years, with the development of science and technology, great changes have taken place in China’s coal industry. Arming coal mines are being equipped with various advanced technologies. However, due to the poor underground working environment, the gas, dust, water and fire And other natural disasters still threaten the safety of mines. Therefore, China attaches great importance to the automatic detection of mine safety parameters. In the mine automation testing, the wind speed and air volume are one of the important safety parameters in the mine. Wind can not only give the mine
