| Abstract: | Pillarless sublevel caving method is widely used in underground metal mines in China, but it needs some applicable conditions. Whether this method can be applied in Laofu Iron Mine still needs further analysis and demonstration. According to the specific geological situations and rock mass conditions in Laofu Iron Mine, the applicability of pillarless sublevel caving method in this mine is analyzed from the aspects of the applicable conditions of the mining method as well as the cavability evaluation of rock mass and ore body. Through the comprehensive analysis, it can be concluded that pillarless sublevel caving method is suitable for Laofu Iron Mine in underground mining, which can realize the safety and efficient mining. |
