Fiber-reinforced foam tail fill (FRFTF) has been widely investigated in the field of foamed backfill because its high strength and toughness. However, fiber enhancement damage mechanism FRFTF still need to be further explored. The pore crack growth particle structure distribution features three kinds basalt (B), polypropylene (PP), glass (G) fibers on were porosity, fracture, sphericity, fractal dimension quantitatively probed by X-ray micro-computed tomography combined with uniaxial compression (UCS) SEM, while spatial porosity fracture was analyzed 3D reconstruction technology. Laboratory findings demonstrate that increases from 1.46% 4.74% increase content 0.3% 0.9%. This is related weak adhesion between fiber. Adding blowing agents could well enhance morphology FRFTF, reduce number principal cracks trapped within specimens, maintain structure’s integrity. relationship FRFTF’s UCS value porosity/fracture closely nature quantity fibers, overall performance best among others. As quality shifts 0.9%, specimen’s adversely correlated porosity. In current study, internal connection FRFTFs are studied microscopically. combination macro-mechanical microscopic provides a new research idea for materials during implementation fully mechanized mining technology hard rock mines.
