摘要
针对食水井石场爆破区域环境较复杂的特点,选择深孔爆破技术方案,采用正三角形布孔和复合爆破网络,优化爆破微差时间和堵塞长度,工程实践表明,爆破效果良好,爆破振动和飞石控制达到了预期效果。
According to the complexity of the environment in the blasting area of the block field around the fresh water well, the deep hole blasting technology was chosen with applying regular triangle hole arrangement and composite blasting network and optimizing blasting millisecond time and stemming length. The engineering practice showed that the blasting results were satisfactory and the blasting vibration and flyrock were controlled as expected.
