⑴ 采礦專業 英語翻譯

本設計是達茂鐵礦露天開採的工藝與開拓設計，年產量200萬噸。This opencut exploitation and pioneer design is applied to Damao Iron Mine, with an annual output of approximately 2 million tons.
採用境界剝采比不大於經濟合理剝采比的原則圈定露天開采境界。Open-pit boundary is contoured with the application of the rule of boundary stripping ratio less than or equal to economic stripping.
並進行可采儲量及平均剝采比的計算。And make a caculation of proved reserves and average stripping ratio.

用礦山延伸速度驗證生產能力。Throughput is verified by extension rate of the mine.

編制露天礦採掘進度計劃時，平均剝采比乘系數的方法初定生產剝采比，電鏟的效率根據類似礦山選取。 When working out the open-pit excavation schele, proction stripping ratio is initially decided by the approach of average stripping ratio mutiplied by coefficient while efficiency of electric shovel selected on the basis of similar mines.
本礦採用斜坡汽車螺旋坑線開拓。 The mine is exploited by vehicles along the slope of the spiral pit-line.
工藝部分包括穿孔設備選型及其數量的計算、電鏟設備的選型及其數量的計算、汽車數量的計算及選型、推土機選型及數量計算、輔助設備的選型及數量的計算等。Techniques include the selection and caculation of drilling equipments,electric shovels,vehicles,bulldozer as well as assistant auxiliary equipments.
爆破方法是選擇及葯量計算，運輸調車方式是選擇，排土方法的選擇及排土計算。 Blasting method is the selection of dosage and caculation;shunting method is the selection as well as the selection of mping and and mping caculation.
關鍵詞：露天開采 開拓 工藝 採掘進度計劃
Key words: open-pit exploitation;excavation;techniques;excavation schele

同學，累死我了；一個多小時翻譯的你的這篇文章，^_^。
