摘　　要：为满足矿山回采爆破需要,急需研发一款使用效果良好且价格低廉的炮孔装药空气间隔器.针对90、110、160 mm三种直径的炮孔进行室内实验,得到空气间隔器随炮孔直径和装填高度变化的受力规律.在此基础上,优化设计出一种科学合理的炮孔空气间隔器,并用于紫金山金铜矿地下采场的爆破工业试验.研究表明:空气间隔器使用方便,爆破效果良好,爆破成本大幅度降低,通过实验设计得到的空气间隔器是合理的.In order to meet the needs of mining blasting,it is necessary to develop a new type of high proficiency and lower cost air-spacer. For this purpose,some laboratory experiments were carried out for three specific kind of holes,with the diameter of 90 mm,110 mm and 160 mm,respectively. As result,the force law of the air-spacer,with the diameter of the hole and the filling height was obtained. A highly responsible scientific blasting hole air-spacer was designed on this basis,and was used at the Zijin Shan Gold-copper Mine for the blasting industry experiment. The results show that the air-spacer was convenient to use,the blasting effect was good and the blasting cost was greatly reduced. The air-spacer obtained by experimental design is reasonable.
