摘　　要：深孔药壶爆破技术目前尚未形成一套完善的工艺,采用这一技术结合浅眼药壶爆破在珠海临港工业区大平湾二期填海工程中的成功应用,不仅满足月产量150万m3的施工要求,而且还大大降低工程施工成本,提高了工程效益。介绍采用孔径140 mm的深孔药壶爆破结合浅眼扩壶爆破的施工工艺及参数计算方法。The deep-hale springing blasting combined with the technique of shallow-hole and pot blasting was successfuUy applied to the engineering of filling the sea in industry area of Zhuhai city. The blasting not only meets the requirements of the yield of the month 1 500 000 square constructions, but also lowers the engineering construction cost and increases engineering performance. The use of 140 mm＇s aperture the construction craft and parameter calculation methods of the technique combined with the technique of shallow-hole and pot blasting are introduced.

关 键 词：深孔药壶爆破 爆破参数 施工技术
