Investigation Of The Structure Schemes And Optimization In Deep Mining Stopes Of Tonglushan Mine

Tonglushan mine is about to enter deep mining stage, ore body attenuation intricacy and exploitation specification intricacy. In order to satisfy Daye non-ferrous metal corporation's require for mine quarry, and also in order to improve deep mining technical and economic target; this article combine Tonglushan mine's deep-seated deposit occurrence characteristics, aim at optimizing stope structure, compromise mining engineering's integrity and gender, analyses stope structure's influence factor target-oriented; adopt system synthesis measure indices, process stope structure conceptual research.It combine Tonglushan mine deep-seated deposit's exploitation specification and production status, adopt experience antitheses to process primary election for system of mining, with the precondition that ascertain Tonglushan mine's deep mining method is upper to lamination stowing method, according to basic drawn unitary various combination as well as brought down drilling outfit's differ deploy, it studied out four feasible programs of stope structure. It screen out the mine dilution rate, the stope loss rate, the extraction-to-cut rate ,mining cost ,the worker labor intensity, the operational security degree, the equipment configuration level, the mining work efficiency and the the easy degree of process as target and then founded evaluating indicator system, grounded on synthetic measure theory. It divieded scheme selective impact factor into three classes-pacing factor, objective factor and human factor according to its attributes. And then synthesized these three factors as on single indices to reflect each conceptual resultant effect,by counting each conceptual syntheses measure indices to select the scheme with maximized resultant effect as Tonglushan mine's deep mining stope structure optimal decision.Syntheses measure evaluation model supply theoretical method reference to stope structure alternative optima problem ,and has definite theory directing or assigning role and activity sense for Tonglushan mine's deep mining production practice.
