摘要
通过研究不同岩性的合理孔间及排间微差间隔时间 ,并利用高精度雷管逐孔起爆新技术 ,可有效地控制爆堆形状和破碎块度 ,改善爆破质量 ,降低采矿总体成本。
By means of controlling appropriate interval of firing time between holes and holerows and adopting high-precision detonator,the shape of muckpile and the size of rock broken can be controlled effectively,thus achieving high quality of blasting and decrement of mining cost.
