平朔东露天矿半连续工艺采掘方案研究

Research on several mining scheme of semi-continuous process during shift and production period in east open-pit mine

对平朔东露天矿西工作帮1290平盘半连续工艺系统的组成和作业过程进行了介绍,主要对半连续工艺系统在移设期和正常生产期间,从经济和技术的角度,对半连续系统剩余爆量采掘方案和红粘土采掘方案进行了分析和探讨,并提出了合适的采掘方案,经过现场实践验证,该方案适合东露天矿半连续正常运行需要。

The article introduces the composition and operation process of 1290 flat semi-continuous process system in west working slope of east open-pit mine. During shift and normal production period, from economy and technology aspect, the article analyzes semi-continuous system surplus blasting amount mining scheme and red clay mining scheme, and presents suitable mining scheme. Through site practice verification, the scheme is suitable for semi-continuous normal operation in east open-pit mine.
