In view of the adverse conditions in Minxian Tianhao gold company, such as extremely broken and thin ore-body, low grade, high filling costs, disallowed surface collapse etc. and based on the field investigation and mechanical testing, the tunnel-type upward continuous mining with waste rock filling along the strike is obtained, which is appropriate to the ore-body. This mining method has basic features of non-explosive, continuous shipment of broken rocks, drift upward filling with waste rocks, small cutting, high level of mechanization and safety mining. In practical engineering application, the mining rate reaches 90% with dilution rate of 8%.%针对岷县天昊黄金公司矿岩极为破碎,矿体薄,品位低,充填开采成本高,地表不允许塌陷等不利条件,在现场调研、力学试验等综合分析基础上,经深入研究,确定采用适合该矿体特征的沿走向脉内巷道式上向废石充填连续采矿法.该采矿方法的基本特征是无爆破落矿、破岩-装运连续、进路式上向废石充填、采切工程量小、机械化程度高、回采安全性好,实际工程应用实现了回采率90％,贫化率8％.
