基本解释

Research on the safety and stability of slope in open-pit mining is very significant to safety production of open mines.
研究露天開採邊坡的安全穩定對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.
探討了地下水對露天採場邊坡穩定性的影響，竝對目前存在的問題作了必要的說明。
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.
露天開採比地下開採有很多的優越性，但缺點也是非常明顯的，那就是在開採鑛石的同時，還要剝離大量的巖石。
