| 摘 要： | 针对那林金矿矿体倾角缓、地质品位低、矿岩非常破碎的开采技术条件及矿山近年生产勘探出许多中厚矿体的具体情况,进行了中深孔无底柱分段崩落采矿法试验研究。介绍了无底柱分段崩落采矿法试验方案、回采顺序及回采工艺,探讨了与采矿方法相关的技术和管理问题。现场工业试验表明,无底柱分段崩落采矿法可以解决留矿采矿法采场作业不安全、放矿困难的问题,取得了良好的应用效果。

| Abstract: | Aiming at the mining technological conditions in Nalin gold mine, such as gentle inclined orebody, low grade, cracked rock mass and medium-thick orebody, experimental study on medium-length hole non-pillar sublevel caving mining method is carried out. The experiment schemes, mining sequence and technique of the new method are introduced. Some technical and management attentions are discussed as well. In-site industrial experiments show that the new method can solve the problems of danger in production and ore-drawing difficulties. The application effects are ideal. |
