摘　　要：露天矿山大型复杂爆破网路设计需要综合考虑孔网参数、连线方式、炸药单耗和雷管微差延时等因素,因此为爆破设计和优化带来了一定的困难与挑战。为快速准确地解算复杂爆破网路,定义了炮孔和导爆管数据结构,进而提出广度优先同步前进搜索(BFSS)算法,有效实现了复杂爆破网路的解算,得出雷管的引燃时间和起爆时间。在此基础上进行了起爆模拟、点燃阵面和起爆等时线等爆破效果分析,为爆破网路设计优化提供了重要的理论依据。Complex blasting network design of open-pit mine needs to consider parameters of blasthole network,connection mode,specific charge,millisecond delay of detonator and so on,which brings difficulties and challenges to design and optimization of blasting.In order to solve complex blasting network quickly and accurately,the data structure of blasthole and nonel tube were defined.Furthermore,breadth-first synchronous search（BFSS）algorithm was proposed,which implemented to the blasting network effectively.Meanwhile,the ignite time and the detonation time of detonator were acquired.Then,blasting effect such as detonate simulation,burning front and detonating isochrones could be analyzed,which provided an important theoretical basis for design and optimization of blasting network.
