某铜矿露采施工工艺控制

摘要

土屋铜矿露天开采以来，矿石损失、贫化严重，爆破大块率高，爆破对边坡稳定破坏较大，边坡角平台标高等技术指标以及运输道路质量等方面达不到设计要求。因此，在露采施工过程中对各主要影响因素采取相应的控制措施，实现了矿山露采施工安全、高效、连续的生产作业，创造了良好的经济效益。%The opencast working of Tsuchiya copper mine has resulted in serious problems, such as ore loss, sever dilution and large blasting chunk rate, greatly influencing slope stability. The elevation of slope angle and the quality of road transportation can't reach the design requirements. There-fore, some measures must be taken to achieve safe, efficient and continuous operation in opencast working construction to produce significant eco-nomic benefit.
