| 英文摘要 | Aiming at the technical challenges in the phosphorous mine in Hubei, China, such as, filling the long-distance and complex working conditions of coarse-grained tailings, the flow and long-distance pumping resistance characteristics of coarse-grained tailings filling slurry were studied by loop test and numerical simulation method. The main innovations achieved in this study are as follows: (1) the CSKY01 filling modifier, Independently developed by Changsha Institute of Mining Research Co., Ltd., can significantly improve the flowability of the coarse-grained tailings' total solid waste filling slurry, (2) the multi-loop full-scale loop test shows that the slurry flow resistance increased by about 4% to 13% after stopping the pump for 0.5 to 24 h and restarting, (3) the resistance loss along the pipeline was found to be directly proportional to the slurry transportation speed and inversely proportional to the pipeline's cross-sectional area. A reasonable pipe diameter and flow rate for the transportation of filling slurry were determined through pipeline resistance loss and cost-benefit analysis, (4) a total solid waste filling system was constructed to handle long-distance and complex working conditions. The system achieved a filling speed of 80-100 m3/h, with a filling concentration of 82%-84%, and the slurry in paste form allows the filling system to run smoothly. A field industrial test confirmed that the strength of the stope filling-body R28 reached 4.2 MPa, which can meet the requirements of mining safety. This study successfully demonstrated the comprehensive utilization of all solid waste resources in phosphate mines, providing a promising idea for the green mining of phosphate mines. |
