| Abstract: | Based on an introduction of block arrangement for mining gently-dipping orebody, effect of block arrangement on the dilution rate of ore stopping method was analyzed. Then, advantages and disadvantages of two kinds of block arrangement in mining gently-dipping orebody for the stoping dilute rate were analyzed in terms of technique and economy, which might be of guidance and reference for future practice in selecting block arrangement for mining such kind of gently-dipping ore body. |
