Pillar pre-isolation sublevel stick-filling mining method and ore body therefor

The invention discloses a pillar pre-isolation sublevel stick-filling mining method and an ore body therefor. The pillar pre-isolation sublevel stick-filling mining method comprises the following steps of 1, dividing the whole mining area into multiple zones, dividing each one of the zones into a step-I stick chamber, a step-III stick pillar, a step-II stick chamber and a step-IV stick pillar orderly arranged along an ore growth direction, and 2, orderly carrying out stoping on the step-I stick chamber, the step-II stick chamber, the step-III stick pillar and the step-IV stick pillar, wherein the same-step stick stopes in all the zones are stoped simultaneously. The pillar pre-isolation sublevel stick-filling mining method has the advantages of low mining cost and high production efficiency.
