研究露天開(kāi)採(cǎi)邊坡的安全穩(wěn)定對(duì)露天鑛山的安全生産具有重要意義。
The influence of underground water on side slope stability of open-pit mining stope was probed. The existent problems at present were explained.
探討了地下水對(duì)露天採(cǎi)場(chǎng)邊坡穩(wěn)定性的影響，竝對(duì)目前存在的問(wèn)題作了必要的說(shuō)明。
The open-pit mining has more advantages than underground mining, but its disadvantages is also very obvious, that is, a lot of rocks are also peeled in minerals exploitation.
露天開(kāi)採(cǎi)比地下開(kāi)採(cǎi)有很多的優(yōu)越性，但缺點(diǎn)也是非常明顯的，那就是在開(kāi)採(cǎi)鑛石的同時(shí)，還要?jiǎng)冸x大量的巖石。
