Abstract:

To solve the problem of inconsistent allowable vibration standards in the production operation area of the coal industry,this article systematically analyzes the vibration characteristics of the main vibration sources in coal industry buildings,and uses the 1/3 octave band analysis method and vibration weighting analysis method,combined with parameters such as vibration intensity、frequency、direction and exposure time,to construct a graded vibration control evaluation standard with exposure limit,fatigue efficiency reduction limit, and comfort reduction limit as the core.The research results indicate that using the allowable vibration weighted acceleration level as the vibration control standard is conservative and more conducive to labor protection.
