| Abstract: | The large-diameter longhole mining method was used to recover the pillars in Anqing copper mine. The height of level stoping was 120m. The stability of fillbody when recovering the pillars was a noticeable problem. The authors make an analysis of both the experimental study on the parameters of the dynamic loading mechanics of tailings-cemented filling and the fillbody stability in Anqing copper mine as well as an approach to the large-diameter longhole blasting techniques. |

| Keywords: | Fillbody stability Confining pressure Limiting strength High-level pillar Large-diameter longhole blasting |
