... stability have only been investigated in a small number of studies. In China, several types of nonsalt interlayers composed of a thin layer of salt with little halite are typical in the form of rocks for which thicknesses vary from dozens cm to more than one meter. For example, the Jintan salt mine has...

The experimental results show that increasing water content and decreasing fracture thickness lead to more wave transmission and less wave reflection. Wave attenuation decreases with rising water content within the range of 0% – 75% and reducing...
