摘要
<正>The experiments, which include the complete stress-strain curves, triaxial compressive loading history and the main factors affecting the compressive strength of the material, were made to research the mechanical properties of paste-like fill material. The results show that the material still has a relatively high load-bearing capacity after yielding. From the view of the backfill strength, the suitable content of the fine particles in the aggregates is 20%, the curing temperature of backfill slurry is about 20 centigrade degrees or higher. The backfill strength can reach 2. 5-3. 6 MPa when the binder dosage is 5%-8%. It can meet the needs for mining with backfill.
