摘要
为保证主厂房水平薄层灰岩岩壁吊车梁岩台的成型,使超欠挖控制在技术条款要求的范围之内,进行了生产性钻孔爆破试验。试验结果表明,爆破效果达到了设计技术要求。
In order to guarantee the formation of the rock-bench for the crane-beam on the horizontal thin-layer limestone rock wall in the main power house and ensure the over or under excavation to be controlled within the specified limit in the technical specifications concerned ,the productive drilling and blasting tests are carried out. The test results indicate that the blasting effect has met the requirement of the design specification and then the initially-selected blasting parameters can be used in the actual excavation as well.
