摘要
在深孔中应用竹竿间隔器进行底部空气间隔爆破的基础上 ,尝试了上部空气间隔吊装填塞技术 ,方法非常简单易行 ,材料因陋就简 ,增加成本非常少。
Based on bottom air interval blasting method using bamboo rod spacer,upper air interval blasting technology using suspended cartridge has been tested.The new method is very simple and causes only few addition of cost thus improving significantly the blasting performance and increasing economic benifit.
