|Title:||Acoustical properties of coal||Authors:||Chew, C.H.||Issue Date:||1987||Citation:||Chew, C.H. (1987). Acoustical properties of coal. Applied Acoustics 21 (3) : 235-240. ScholarBank@NUS Repository.||Abstract:||A model has been proposed for bituminous coal which takes into consideration the transverse isotropic properties of coal and the effects of the nature of fluid in the pores on its acoustical properties. The predicted values were then compared with the experimental results performed on a bituminous coal slab, and good agreement was found between the predicted and experimental values, thus verifying the proposed model. The sound velocity through coal increases and the attenuation decreases as the pores become saturated with water. © 1987.||Source Title:||Applied Acoustics||URI:||http://scholarbank.nus.edu.sg/handle/10635/57861||ISSN:||0003682X|
