红沙泉一号露天煤矿首采区及拉沟位置方案优化

Optimization for the first mining area and pioneer cut position scheme in Hongshaguan NO.1 cpencast coal mine

在分析了红沙泉一号露天煤矿的地质条件及煤层赋存情况等基础上,确定了首采区的大致位置,在首采区内提出了3种拉沟位置方案,并进行了优化分析,确定了合理的首采区及初始拉沟位置,研究结果对红沙泉一号露天煤矿首采区及拉沟位置方案的选择具有一定的参考价值,文中的研究思路值得其他同类型露天矿借鉴和参考。

Based on the analysis on the geological conditions and coal seam conditions of the opencast, this paper pointed out the approximate location of the first mining .area. Meanwhile, the paper provided 3 options of pioneer cut position in the approximate first mining area. It determined a reasonable first mining area and the location of the pioneer cut position after optimization. The results of this study had some reference value for the design of first mining area and pioneer cut position of Hongshaquan opencast, while the research ideas of this paper can be referenced for the other same type of open pit mine.
