Study on mechanical and seepage characteristics of water-saturated coal under rapid cold and heat shock by liquid nitrogen freeze-thaw and microwave heat injection

This study proposes to explore the coal mechanics and seepage characteristics under the coupling of water-saturation, freeze-thaw and different temperatures. The original coal of 9105 working face in Wangzhuang Coal Mine was taken as the research object, and non-contact digital image processing was...
