Abstract: Under the guidance of building an efficient, green and environment-friendly mine, the full tailing cemented filling mining method has been widely promoted and applied as a key support technology for safe, efficient and green mining due to its advantages of treating tailing, controlling surrounding rock deformation and reducing the impact of mining on the ground environment. In the process of mine application, the tailing slurry is mostly transported by pipeline. Under the complex terrain conditions dominated by steep valleys, especially in the process of long-distance, large drop and reverse slope transportation, problems such as pipe blocking, pipe explosion and even damage to the conveying pump are easy to occur, which become the bottleneck problem limiting large-scale filling. Taking Buriticá Gold Mine as an example, on the basis of systematic experimental research to obtain complete filling test data, combined with the characteristics of mine general layout, topographic conditions and the relative regional position of goaf space, the tailing transportation scheme is compared and optimized. For the first time, the pressure filter tailing cable tram transportation and reconstruction slurry filling technology scheme adapted to the conditions of large drop mountain is proposed, and it is successfully implemented and operated on site. The mine production operation shows that a single set of filling system can meet the production demand of 3 000 t/d in the mine. The filling slurry is paste-like, the system runs stably, the ratio parameters are accurate, and the filling quality is guaranteed. In summary, the technology scheme of transporting and reconstructing slurry by pressure filter tailings cable tram has the advantages of short process, less land occupation, high efficiency, economical and reliable operation. Under the condition of large drop mountain, the filling technology can realize the efficient transportation, preparation and low cost of filling materials, which has good popularization and application significance.
