| 摘 要： | 电爆网路目前仍然在工程中被采用。结合爆破工程施工规模和现场布孔情况,必须对网路电阻进行严格的设计和计算,并进行实测,进而确定安全有效的起爆网路。计算和施工结果表明,在高电磁场区域,根据每个工作面爆破规模大小,一般考虑排间并联,排内串联。当爆破规模达到2万方以上、工作面为2~3个时,计算要使通过每个电雷管的电流不小于2.5mA,可以采用2组并联、组内串联方式起爆。同时,工作面杂散电流应不大于30mA。

| Abstract: | Electric detonating circuit is still mostly adopted in engineering project now.Combined with construction scale and on-site hole disposal,the circuit resistance must be designed and calculated seriously to decide safety and effective detonating circuit.The result indicated that parallel connection among the line and series connection within the line shall be generally considered in high electromagnetic area based on the blasting scale of each working face.When the blasting scale came up to over 20000m3 with... |
