The application of tailings cemented filling technology in Xichao molybdenum mine

With the mining process of Xichao molybdenum mine,the related gobs were growing,and some gobs were connected to each other.In order to solve the problem of impact ground stress and roof ground dropping induced by mining,some tests were accomplished and the method to optimize designing was studied.The results showed that:The filling ability in this mine is 70~90m3/h.Because of the impeccable self-control system and the optimized method,the density and flow can keep stable.Besides,the physical parameters can satisfy the requirement of production.
