| Abstract: | No.17 underground stope of Banshi Mining Company belongs to middle-thick ore body that are mined with pillarless subdrift caving method.The usual trouble in mining activity is high loss of ore and high rate of depletion.According to result of analysis & research,the decision is made to adopt section-wise drilling and section-wise open stoping method to the middle-thick ore body below 18m level.The method brings advantages of high ore recovery rate,low loss of ore and low rate of depletion thus increases uti... |
