【摘要】 在结合安庆铜矿2号矿体特点的基础上,以利文斯顿爆破漏斗理论为依据,通过分别在SK-Cu矿石、Fe矿石和Fe-Cu矿石中进行单孔爆破漏斗试验,得出了爆破漏斗最佳状态的技术参数,并在此基础上,进一步得出了该矿体凿岩爆破的爆破参数,为矿山今后降低凿岩爆破成本、提高缓倾斜矿体安全开采技术、降低大块率、强化出矿等提供了宝贵的依据。更多还原

【Abstract】 In light of the characters of the No.2 orebody in Anqing Copper Mine and based on Livingston blasting cra- ter theory and through the single-hole blasting crater tests on SK-Cu ore,Fe ore and Fe-Cu ore respectively,the optimal technical parameters of the blasting crater were obtained.On this basis,the optimal blasting parameters for the drilling- blasting of this orebody were also drawn,providing a precious basis for the future reduction of the drilling-blasting cost,im- provem(?)nt of the safe mining technology for gently inclined orebodies,the decrease of large fragmentation rate and the inten- sification of ore drawing.更多还原
