Study on loading and failure instability mechanism of “support-surrounding rock” system in large dip angle and large mining height working face

Physics of Fluids
The stability of “support-surrounding rock” system in a large dip angle and large mining height working face is the key to safe mining of the working face. A three-dimensional large-scale simulation experiment platform and a supporting hydraulic support were developed by combining field measurement, theoretical analysis, and three-dimensional physical ...
