The stability of backfill plays a crucial role in the process mine operation. In this study, author combined indoor experiments, surface fitting, numerical simulation, and theoretical derivation to investigate how filling times (FTs), cement tailings ratio (CTR), minimum CTR position (MCFP) affect uniaxial compressive strength (UCS) fracture evolution behavior LCB. findings demonstrate that an augmentation FTs reduces UCS Moreover, highest resulting from diverse MCFP amounts 2.25 times. When once filling, sustain damage as result cracks penetrating, whereas LCB are filled multiple first encounter at layered contact surface, followed by gradual spread until penetrate Through interactive regression model, it is evident FTs, CTR, significantly UCS. Additionally, interaction between has considerable impact on Based increase results wider large displacement area generated backfill, leading greater horizontal vertical displacement. significant lateral maximum stress backfill. Theoretical verifies top or middle layer UCS, which consistent with experimental simulation. This paper elaborates mechanical mechanism behind MCFP. These can provide foundation for assessing durability subsequent stages.
