摘要
通过分析全留沟-搭桥、全留沟、半留沟各自的特点,从技术和经济上对3种内排土场留沟方案进行比选,得出需要修筑1条连接首采区东端帮与内排土场东部的运输道路,即采用全留沟-搭桥措施,来缩短卡车运距,降低运输成本,减少电铲的二次剥离量,提高作业效率。综上,从技术经济角度建议采用全留沟-搭桥方案,确保黑岱沟露天煤矿转向顺利进行。
This article analyzes the characteristics among whole left ditch - bridge, whole left ditch and half left ditch, compares these three kinds of schemes for leaving a ditch in inner dump from technical and economic aspects. That needs to build a transportation road which connects the eastern end of the first mining area with inner dump, which adopts whole left ditch - bridge measure to shorten the length of haul truck and to reduce transportation costs and the secondary stripping quantity to improve the working efficiency. In conclu- sion, it advices to use the solution of whole left ditch - bridge from technical and economic angle to make sure Heidaigou Open - pit op- erate smoothly.
