摘　　要：为有效解决土屋铜矿露天开采爆破施工过程中大块率高、边坡安全、损失贫化率严重等技术难题,通过对深孔控制爆破中大块率控制、爆破振速控制以及损失率、贫化率控制等方面的研究,得出一种最优的方案:设计合理的爆破参数、采用间隔装药、选择合适的爆破器材、运用逐孔起爆技术、边坡控制爆破、采取分钻分爆的工艺方法施工、在矿岩接触带采取弱松动爆破。这一方案在实际采矿中取得了良好的爆破效果。In order to solve the technical problems in blasting construction of the Tuwu Copper mine, such as high boulder yield, slope safety,loss and dilution ratio, an optimized solution was put forward by using deep-hole con- trolled explosion, including rational blast parameters, interval charging, appropriate explosive materials, hole by hole firing, slope eontrol blasting technology,separate drilling and separate initiating in the process of construction, weak loose blasting. Finally,good blasting effeet was achieved in actual mining by using this scheme.
