低丘缓坡地带露天中深孔爆破岩石大块率的控制技术措施

摘要

The lumpiness of rock blasting has direct impact on engineering quality. Based on the earth and rock engineering case of mild slope develop-ment program in Lishui ecological industry, a key program of Zhejiang province, the causes and specific reduction methods of boulder yield in mild slope area are analyzed and presented. And good blasting results are obtained.%岩石爆破的块度大小对工程质量有着直接的影响，该文通过浙江省重点项目---丽水生态产业集聚区低丘缓坡开发项目（莲都组团1）二期土石方工程的实践，分析总结了低丘缓坡地带露天中深孔爆破岩石大块度产生的原因及其降低大块率的具体措施和方法。经现场实践验证，获得了较好的爆破效果。
