摘要
乳化炸药具有良好的抗水性能和抗低温性能,在冻结井施工被广泛采用,但是在施工中如果不了解乳化炸药的性能和操作使用不当,往往会出现装药拒爆现象。结合现场施工情况,并根据试验分析,产生盲炮的原因主要是炮孔中水结冰、体积膨胀而引起的乳化炸药的静压减敏作用。根据产生拒爆的原因,采取了克服拒爆的措施,取得了良好的爆破效果。
Emulsion explosive with good water resistance and low temperature resistance, is widely used in frozen shaft construction, but if you don＇t understand in the construction of the performance of emulsion explosive and improper operation, often charging misfire. Combined with the construction site conditions, and according to the experimental analysis, causes of blindness gun are mainly caused by whole water freezes, the volume expansion of static pressure desensitization of emulsion explosive. According to the cause of misfire, take the measures to overcome the misfire; good blasting results have been achieved.
