摘要(Abstract):

以嘉达采石场扩大生产规模为实例,介绍了深孔松动爆破技术的爆破参数计算、起爆网路的设计和可靠性分析,为减小爆破危害采用了孔间“等间隔延时”起爆网路,对控制爆破震动和飞石效果明显。
By taking improving the production capacity of Jiada quarry as an example,the paper introduced the calculation of blasting parameters,the designing of detonating network and the analysis of the reliability of net-work,For reducing the blasting damage,the detonating network of the equal interval millisecond delay among the holes was used and reached a good effect in controlling the blasting vibration and flying rock.
