| Abstract: | In the course of large-diameter deep hole pillar mining with two-step extraction,the stability of filled backfill body in filled stope will affect the entire ore body safety and smoothly mining.In this paper,on the basis of testing and studying on the characteristics of backfill,stability of the stope backfill was calculated and analyzed by using Terzaghi model and the Mitchell et al.calculation method,as result,a reasonable exposed area of stope side was proposed,which provides a theoretical basis for stop... |
