The mine is adopted to open - mining and underground - mining jointly, and the open - mine is divided into north and south stope
由於歷史因素，礦山開采本關先南露天采場后北露天采場原則進行。One of the existing problems of the mine at present is : when the south open stope is over in 2005, where does the open north stope start for the sake of optimizing economic benefit and social benefit and environmental benefit of the mine facing to this problem, based on the large number real data of mine, in view of fuzzy attribute and complexity attribute existing in mine production, this paper applies fuzzy multi - attributes decision method to a lot of feasible technology, economy rational for schemes to appraise to proposes
當前礦山生產存在的問題之一是：南露天采場將於2005年開采結束，何處啟動北露天采場，才能使得礦山經濟效益、社會效益、環境效益保持最優化?針對銅綠山銅鐵礦北露天礦何處啟動最優這一問題，本文在收集大量銅礦山生產實際資料基礎上，針對礦山生產中存在的模糊性和復雜性，提出運用模糊多屬性決策方法對多個技術可行、經濟合理方案進行評價。Abstract : this paper gives the fe simulating analysis of the effect on road construction in the process of mine open - cut, analysis and evaluates stability of road foundation during many rock material steps excavation, concludes that the different conditions, for example, the rock caves, steps and the dis tance between the steps and road have influence on the road foundation stability
文摘:針對礦山在地下開采轉為露天開采過程中，原地采區域在露天采場臺階開挖過程中對露天采場公路建設及運營的影響，進行了數值模擬分析，並對通過各種巖體介質的露天采場公路路基在臺階開挖和汽車運營過程中的穩定性進行了分析評價，得出了在不同條件下，如空洞地區、臺階材料介質、材料界面、開挖臺階與公路距離等對路基穩定性影響的評價。Study on determining open - pit limit under make economic conditions
市場經濟條件下確定露天開采境界的研究The tonglushan copper - iron mine is the key mine of hubei daye nonferrous metals corporation, and it is one of the large - scale mines of nonferrous metals of our country too
銅綠山銅鐵礦是湖北省大冶有色金屬總公司下屬骨幹礦山，也是我國有色金屬大型礦山之一。礦山生產採用露、地聯合開采，露天開采分南北兩個采場。Monitoring and analysis of blast vibration for transforming opencast mining into underground mining
露天轉地下開采爆破振動的現場監測與分析Under the determinate boundary or close condition increasing the height of steps can realize steep slope mining and engender more much stope space, which will be propitious to balance stripping ratio, increase storage for exploiting and improve mining intensity and production capacity
摘要在露天礦一定的剝離境界或封閉條件下，大幅度增加臺階高度可以實現陡幫開采和形成更大的采場空間，從而有利於礦山平衡剝采比，增加備采儲量，提高礦山開采強度和生產能力。Electrical installations for open - cast mines and quarries - recommendations for winning, stacking and processing machinery, pumps and low signal level and communications systems
