Abstract

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.

Description

technical field

[0001] The present invention relates to a mining method and an ore body, in particular to an ore pillar pre-segregation segmental strip filling mining which is suitable for mining an ore body that is not stable and the surface does not allow subsidence of a gently inclined or steeply inclined thick metal ore body Law. Background technique

[0002] When mining extremely unstable, thick, large and low-grade ore bodies, the caving method is generally used for mining. However, caving mining will cause surface subsidence and affect sustainable development. Especially when mining under farmland, the surface subsidence is not allowed, so filling mining is required mining method, filling mining method has high cost and low production efficiency. Contents of the invention

[0003] The object of the present invention is to provide a mining method for pre-isolation of ore pillars, segmentation and block filling and an ore body. The mining method has low mining cost a...
