Discussion on The Way of Sill Pillared Mining in Phases in Upwards Laneway Stoping-filling Mining

As the phase of division,in upwards laneway stoping-filling mining exist phase pillarless,and the stage of Pillarless reserves accounted for 20% of reserves in the entire period.How to effectively recover this part of the ore,for the mine of great significance.In this paper analysis pillarless orebody formation process in upwards laneway stoping-filling mining of filling mining of Xiaotieshan Mine.Put forward an effective solution from the design phase of ore mining pillarless program.Practice has proved that achieved good economic results,of the same mine also has a certain signifecance as reference.
