Abstract

Some critical issues in application of pillarless sublevel caving method are analysed.Further research should be done to natural classification of capping rock;shape & form of breaking-down rock;relationship between drawing-out rock,loose rock and breaking-down rock.To optimize the structural parameters,reduce ore's dilution rate and increase mine's benefit,it is of great importance that the drawing operation andblasting operation are studied as a complete unit.
