无爆破连续采矿法在露天磷矿的开采实践

Continuous mining method without blasting in open pit phosphate mine

介绍了露天矿无爆破连续采矿法,该采矿方法采用新型露天采矿机,无需穿孔爆破和选矿厂粗碎工序,连续作业,开采成本低,采场粉尘和噪音小,剥离岩土内排,节省土地,覆土植被可与采矿剥离平行推进。

The paper presents a blast free continuous mining method in open pit mine, which features continuous operation, low cost of mining, little dust in stope, reduced noise, internal disposal of stripped rock-soil, less land used and possible parallel progress of earth covering, planting and stripping for mining by using new type surface mining machine with no need to have processes of drilling,, blasting and preliminary crushing.
