- Abstract
Taking Dongshengmiao lead-line mine in Inner Mongolia as the subject of study, the commercial test on sublevel open slope mining method in drilling stages was carried out. The results show that the mining method has the advantages of little cutting ratio, short slope preparation term, centralized production, large production capacity, reliable ground pressure maintenance, low ore loss and dilution rate, It not only improves the ore caving performance, lowers the physical labor intensity of workers, enhances the safety of mining operation, but also results in encouraging technical and economic performance as follows : the mining cut ratio was 3. 31 m./k t, the ore loss rate was 1. 60%, and the dilution rate was 1.95%. Compared with application of the short-hole shrinkage method, an addition annually pro fit of 17, 020,:300 yuan could be obtained from the mining operation with this method. The results of the mining test can be provided as technical support for the subsequent operation of the mine and as the reference for similar mines.
