摘要(Abstract):
在大型土石方爆破施工中,为了降低爆破振动并保证其爆破网路的准确传爆性,通过对工程中采用的孔内孔外联合延时非电起爆网路进行改良,最后达到了无限分段、单孔单响、传爆可靠的要求。经过在工程实践中检验,取得了很好的效果。
In order to reduce blasting vibration and ensure a reliable diffusing detonation,the paper mended the delay non-electronic firing circuit of out hole and down hole combining delay firing employed in engineering,resulting the blasting network in infinite division and single hole to single hole initiation,and therefore,reaching a reliable blasting propagation.The mending proved practical in the engineering by giving excellent blasting effect.
