平朔东露天原煤运输暗道破碎口移设步距优化

Moving step distance optimizing of raw coal transportation underpass crushing mouth in Pingshuo east open-pit mine

为了解决平朔东露天矿端帮运煤暗道破碎口移设滞后严重影响矿坑内排的问题,对原煤暗道破碎口移设步距进行优化,优化采用经济效益定性和定量分析法,并用图像直观反映,确定最佳破碎口移设步距。优化后的破碎口移设步距可协调矿坑原煤运输与采剥排之间的关系,促进露天矿安全高效生产。

In order to solve the problem that the shift lag of crushing mouth of end slope coal conveying tunnel seriously affects the mine drainage,the mine optimizes moving step of crushing mouth of raw coal underpass,the optimal crushing mouth moving distance is determined by qualitative and quantitative analysis of economic benefit and visual reflection of image.The optimized crushing mouth moving step distance can coordinate the relationship between raw coal transportation and stripping and drainage,and promote the safe and efficient production of open-pit mines.
