| To achieve complete extraction of ore,cemented fill is used to fill the voids left by mining.The design of the cemented backfill mix is based on the requirement of stable exposures during the mining sequence.By engineering analogy and academic analysis method,it gives strength requirement of cemented backfill mass for the underground voids of Anqing copper mine,and calculating results can afford strength warranty for mine backfill mix proportion.At the same time it educes the relation of strength of cemente... |
