Natural Frequency of Coal: Mathematical Model, Test, and Analysis on Influencing Factors
The difficulty in enhancing the low permeability of deep coal seams is the key problem restricting gas extraction. The technology of coal rock resonance and permeability enhancement excited by vibration wave is hailed as a new technology to enhance coal seam permeability. In particular, the effect o...
