近年来采用地下深孔大爆破落矿方法的矿山逐年增多,规模也越来越大。大爆破工程成败的关键之一是电爆网路的设计正确与否。根据我矿十多年上百次大爆破的实践经验,大爆破电爆网路的设计须满足以下几点:①确保每个雷管获得足够的、稳定均衡的准爆电流;②起爆电源稳定可靠,变压器容量合适;③网路 In recent years, the use of underground deep-blast mining method of mine increased year by year, the scale is also growing. One of the keys to the success or failure of the blasting project is whether the design of the electric blast network is correct or not. According to my mine more than a decade of 100 large blast practical experience, blasting electric burst network design must meet the following points: ① ensure that each detonator access to adequate, stable and balanced quasi-current; ② detonation power supply is stable and reliable , Transformer capacity suitable; ③ network
