A Propagation Loss Coefficient Model of Low-Frequency Elastic Wave in Coal Strata Set
Elastic waves cause energy loss during the transmission of coal measures. These losses include propagation loss, dielectric absorption loss, scattering loss, and frequency migration loss. The absorption loss is mainly caused by the inelastic absorption. The scattering loss is caused by the uneven he...
