摘要
研究了东露天矿二采区采区合理宽度及过渡转向方式,通过对剥采比、高差运距及未来生产能力等多方面论证,提出了首采区北部划分2个采区的结论,通过对直角、扇形转向方案的技术对比,对传统扇形转向方式进行了优化研究,最终提出了“L”型扇形转向方式。
The article studies the reasonable width and transition turning mode of the second mining area of the east open-pit mine.Through the demonstration of stripping ratio,height difference transportation distance and future production capacity,the article presents the conclusion that the northern part of the first mining area is divided into two mining areas.Through the technical comparison of the right angle and sector turning schemes,we optimize traditional sector turning mode,and finally present the"L"sector turning mode.
