RESEARCH ON BIG CROSS SECTION STRUCTURE PARAMETRES IN UNDERGROUND MINE OF GONGCHANGLING BASE ON SLS SYSTEM

The paper research the effect of setting-ore jaws towards scatters moving regulations,state deeply the theory basement and computer simulation process,explain the virtur and upswing project of the effect of setting-ore jaws towards scatters moving regulations in the course of big cross section setting ore.Simulate several projects and choose excellent form simulation result by SLS system.Comparing with small cross setting-ore tunnel,simulation result show superiority of big cross setting-ore tunnel.
