摘要
详细介绍了壁式爆力削壁充填采矿法在峪耳崖金矿的应用。对于矿岩界限明显、缓倾斜薄和极薄矿脉采用矿岩分爆、围岩抛掷爆破充填采空区技术 ,降低了损失率、贫化率 ,减小了采场暴露面积 ,提高了矿山综合经济效益。
The application of wall blasting power waste-lifting stoping in Yu'erya gold mine was introduced in detail.For the gentle dip narrow or extra-narrow vein or the vein in which the demarcation line beween rock and ore was clear,the separate blastings of rock and ore was adopted and the technique of filling mined-out area by way of throwing country rock in the course of blasting was used.In this way,the ore olss and dilution rates lowered,the exposed area of stope reduced and the comprehensively economic benefit improved.
