通过分析对比方法对歪头山铁矿下一步铁路直采下降最佳深度进行了论证,其结果表明歪头山铁矿主采场铁路生产最佳下降水平为68m;当铁路下降68m时,才能保证采场各工程顺利衔接,生产运输系统过渡及时合理,才能保证歪头山铁矿主采场在十二五期间实现500万t/a产能。
By analyzing and comparing the results, the optimal depth of straight-line descend of next railway in Waitoushan iron mine is demonstrated. The result shows that the optimal descending level of railway production in the main pit of Waitoushan Mine is 68m. When the railway descends 68m, In order to ensure smooth transition of all works in the stope and timely and reasonable transition of production and transportation system, it is possible to ensure that the main stope of Waitoushan Mine will achieve a production capacity of 5 million t / a during the 12th five-year plan period.
