Research on noise and vibration reduction performance of mine chute in foamed aluminum laminated structure

In order to reduce the working noise of coal chute and to explore a new way of doing so, an idea of using foamed aluminum laminated structure in manufacturing mine chute is put forward. According to the characteristics of chute on working, a new foamed aluminum laminated structure of mine chute is designed. And then, the noise and vi-bration reduction performance of it is studied by theoretical analysis and test. The results show that the new laminated structure of chute can improve the noise reduction and environmental protection performance.
