摘要
介绍了超深孔连续柱状装药水压爆破技术的实验研究和在 15 1m深孔预碎裂爆破中的实际应用。在实验的基础上进行了非金属装药外壳的全长密封连接工艺设计 。
This Paper introduces experimental study on continuous cylindrical charge blasting with water pressure in ultra-deep hole and application in blasting pre-breaking rock in 151 m deep hole.Based on experiments,hermetic joining technology of nonmetallic outer covering is designed for general blasting material for civil use to reliably be used in ultra-deep hole with water.
