Abutment pressure distribution in coalface plays an important role in stress concentration and elastic deformation energy storage in coal or rock seams,so it will affect greatly the occurrence of rock burst.

Fe-26Mn-6Si-7Cr-1Cu alloy is more resistant to cavitation erosion than Fe-20Mn-6Si-7Cr-1Cu alloy, which is mainly attributed to the higher strain-induced martensitic transformation energy and elastic deformation energy under a localized load.
