Abstract:
On the basis of resource endowment and geological features, harsh geological conditions and mining environment for the effective mining and comprehensive utilization of deep resources in Jinchuan Nickel Deposit were systematically analyzed, including high stress, fragmentized ore rock, prevalent deformation, difficult support, complicated rock mechanics and low mining recovery. An integrated technology package has been established for safe, efficient and continuous mining at the huge, complex and deep nickel and cobalt mine by proposing a large-area continuous mining method with honeycomb drives and establishing ground control theory and technology package in high stress and fragmented ore rock, and by developing new backfilling cement material and deep backfilling technology with pipeline transport of high density slurry with coarse aggregate, in order for an efficient exploitation and comprehensive utilization of deep resources in Jinchuan Nickel Mine, hence presenting technological demonstration for the underground mine using cemented undercut-and-fill mining method with stressful, fragmented and rheological rock.
