| Abstract: | Upon analyzing the process of extracting roof and bottom pillars in Xincheng goldmine, the paper presents a new approach to the design of gob layout perpendicular to the ore body and the zone drifts along with the strike of the ore body. A case study was conducted in Xincheng goldmine by the authors. With this process, the general ore loss rate decreases 16.3 percent, and the depletion rate is declined by l 1.8 percent. More than 4183 tons of ores is obtained additionally, creating a direct economic benefit of 5.3632 million Chinese dollars, and the safe condition is also improved to some extent. |
