大型露天煤矿采区转向方式研究

Transition Method from One Mining Area to the Next in Large Surface Coal Mines

依据安家岭露天煤矿实际，提出了可行的采区转向方案，通过定量计算与定性分析确定最佳采区转向方式，保证露天矿从一个采区向另一个采区过渡时期矿山生产的正常接续。所采用的研究方法及研究结论对类似矿山具有参考价值。

Based on the actual conditions of Anjialing Surface Coal Mine, several feasible transition alternatives have been put forward. And the best one has been recommended after theoretical analysis and quantitative calculation, which could guarantee the reliability of mining engnieering during the mining area transition. The adopted method is of universal significance.
