Abstract: The stoping scheme and paste filling system of the large and thick ore-bodies of the west ore-bodies in Chambishi copper mine are analyzed, the applicability of the paste filling strength is testified by adopting the independent intensity computation method, the destruction of blasting vibration to filling bodies is controlled effectively by using the controlled blasting technique with small section. The application results of the upward horizontal drift hierarchical paste filling mining method show that the recovery rate is improved to 75%~80%, the dilution rate is controlled to 6%,the stripping ratio is lowered to 90～100 m3/kt, therefore, the safe stopping with high efficient of the stope in Chambishi copper mine is realized.
