【摘要】 煤矿采掘和地面爆破施工中，爆破可靠性是个重要环节。发生在串联网路或串并朕网路中部的成组拒爆，或者只有一端爆炸的情况，往往令爆破作业者费解。该研究一改往常定性方法描述不良爆破的征兆，通过试验、理论推导、定量分析，评价电爆网路中出现的成组拒爆现象。更多还原

【Abstract】 Blasting reliability is key to the coal mining operation and ground blasting.It is always difficult to understand for blasting operator that the blastholes in group are often misfired in the middle of series or series-parallel network or blasting happens only at one side.In this paper,the phenomenon of misfire blastholes in group in the electric blasting network is assessed for sign of poor blasting through experiments,theoretical derivation and quantitative analysis,but not generally with the qualitative analysis.更多还原
