阿舍勒铜矿充填采用戈壁料作为粗骨料,尾砂作为细骨料,经添加水泥搅拌均匀后通过管道自流输送至充填采场,与粗骨料细磨和泵压输送工艺相比,其流程大为简化且运营成本低,系统生产能力大,充填料浆在管道及采场中呈结构流动,不产生分层、离析等不良现象,避免了管道堵塞,减小了管道磨损。该充填工艺技术制作的灰砂比为1∶8,1∶3的充填体,28 d强度分别达到1.027,3.83 MPa,满足阿舍勒铜矿不同采矿方法的生产要求,为矿山取得了良好的经济效益和技术支撑。
The Ashele copper mine is filled with Gobi material as coarse aggregate and tailings sand as fine aggregate. After being mixed with cement, the tailings are transported to the filling stope by gravity flow. Compared with coarse aggregate fine grinding and pump pressure conveying, The process is greatly simplified and the operation cost is low. The system has large production capacity. The filling slurry flows in the pipe and stope and does not cause any stratification and segregation. It avoids pipeline blockage and reduces pipeline wear. The filling technology produced by the technology of sand and sand ratio of 1: 8, 1: 3 filling body, 28 d strength reached 1.027,3.83 MPa, respectively, to meet the Ashele copper mining methods of different production requirements for the mine made a good Economic benefits and technical support.
