摘　　要：结合某石灰石矿的生产实践,阐述了逐孔起爆和空气间隔装药技术的作用原理和爆破参数的选择。工业试验结果表明：该矿采用中部空气间隔装药技术后,可以显著降低炸药单耗,合理控制矿石粒度25~55 mm的比例,显著提高了电铲装车效率,为其他相似矿山开采提供参考。Based on the practical production of the limestone mine,hole-by-hole blasting and air-deck charge technology principle and the selection of blasting parameters are described. Industrial experiment results indicated that after the application of central air-deck charge technology in the mine,explosive consumption and block rate are released with ore-rock fragmentation controlled reasonable,excavator working efficiency improved,as is also a referrence to provide certain reference for other similar mining conditions of limestone mines.

关 键 词：台阶深孔爆破 空气间隔装药 炸药单耗 大块率
