摘要
根据多年石方深孔爆玻的经验，总结了改善深孔石方爆破效果的主要技术对策有：多排微差挤压爆玻、孔口加压砂包以及可靠的爆玻网路检测等。通过实践证明这些技术措施既提高了爆玻安全性，又能降低爆破成本。
The main technological countermeasures of improving the effectiveness of stonework deephole blasting according to blasting experiences for years are summarized, which include multirow millisecond blasting, sand sack covering on the hole, application of ANFO explosives and reliable network examination. The practice proves that these technological countermeasures not only strengthen the blasting safety but also lower the blasting cost.
