摘要
重铵油炸药具有可用于湿孔与水孔装药、装药简单等优点,其波阻抗与石灰岩的波阻抗相匹配,爆破后块度均匀、无底根、矿石成块率高、粉矿少、后冲和爆破振动小。莱钢石灰石矿将重铵油炸药与空气底部间隔装药爆破技术相结合用于深孔爆破,装填劳动量减少,底根率降低,比用2#岩石粉药年节资3.0万元。
The advantages of emulsifed ammonium nitratefuel oil mixture are charging into hole with water,charging convenience,etc.Others because wave impedance is matching with wave impedance of limestone,blasting block is mean,powder ore is low and the blasting vibration is small,etc.In combination of emulsifed ammonium nitratefuel oil mixture with blasting technique of air bottom dividing charge for deep hole blasting in limestone mine of laiwu iron and steel general works,and so the working quantity of charge is lowered,bottom root ratio is decreased and 0 03 million yuan is saved every year compared with used of 2 # rock powder explosive.
