The failure of a tailing dam occurs due to damage to the particles' micro-structure. Understanding the deformation characteristics of the particle' micro-structure is important for understanding the mechanics of instability in tailing dams. In our study, a series of experiments was conducted using a testing apparatus for micro-mechanics and the deformation(More)
Based on the gently inclined medium thick phosphate rock of the deep part of the east mining section of +2150 level of Jinning-Six mine of Yunnan phosphate Co., Ltd, the similar simulation model experiment of the stability of stope roof under cemented backfilling mining of waste rock was carried out by the mine pressure plane stress modeling experimental(More)
