Reinforcement engineering stability numerical analyzing of JinShandian ore chute

摘要

According to the sloughing control situation of JinShandian mine east area 610 ore chute, the reinforcement scheme was put forward basing on the analysis of the form and cause of chute failure, the mechanics and stress state of chute bonded reinforcement was analyzed by the MIDAS/GTS finite element numerical calculation software. The results show that the displacement value in a few millimeters range after the sloughing control ore chute was supported and maximum scale shear strain happened in sloughing control area upper and lower. The results present the theoretical basis for the evaluation of ore chute reinforcement scheme.
