我矿多年来在平巷掘进、天井掘进、竖井掘进和浅孔采矿的电力爆破作业中,采用的爆破网路为并双串联连接方式。实践证明,并双串联网路准爆率高,从未发生过多孔拒爆现象。在小型爆破中,并双串联连接比较可靠。在一定意义上讲,并双串联连接网路优越于串联、串并联网路(见下图)。
For many years, mine has been used in blasting tunnels, tunnel boring, shaft excavation and shallow hole mining blasting operations, and the burst network used in the mine is connected in series and in series. Practice has proved that double parallel network burst rate is high, never had the phenomenon of porous repellent. In small blasting, double series connection is more reliable. In a sense, and double in series to connect the network superior to the series, series and parallel networks (see below).
