电雷管起爆法在露天爆破中被普遍采用。这种起爆法操作复杂,要求严格,如果雷管质量达不到技术要求或者施工操作不当,发生拒爆的可能性较大。本文对网路的联线方式和接地问题提出一些看法。一、雷管的并-串-并方式并-串-并联方式或称复式串-并联方式,至今仍然是现场采用最多的方式。其雷管联线方法是:每个起爆体由两发并联电雷管组成,孔与孔的起爆体之间串联,再用两
The electric detonator detonation method is commonly used in open blasting. This kind of detonation method is complicated to operate and requires strict requirements. If the quality of the detonator does not meet the technical requirements or the construction is performed improperly, there is a high possibility of catastrophe. This article puts forward some ideas on how to connect and ground the network. First, the detonator’s parallel-string-parallel method-string-parallel connection method, or double-string parallel connection method, is still the most widely adopted method in the field. The detonator connection method is that each detonation body consists of two parallel electric detonators, and the hole and the detonation body of the hole are connected in series, and then two
