| Abstract: | The steep incline and fractured ore-body in Yongshaba Mine of Guizhou Kinlin Group belongs to difficult-to-mine ore-body.For the sake of this,based on the occurrence of these ore-body,six mining methods that can be used are analysed and compared with one another by technical economic analysis.The sublevel drilling open stoping in stage with subsequent filling process is decided to be adopted.The paper introduces detailedly the mining process including structure factors,development works and extraction technology etc.. |
