PHED-1型电子雷管在露天深孔爆破中的应用
|
摘要
以瓮福磷矿下属的穿岩洞矿为例,详细介绍了PHED-1型电子雷管在露天深孔爆破中的应用情况。经过近两年的使用,该电子雷管在瓮福磷矿所属的各矿山累计使用量达4万多发,使用炸药2 000多t,单次起爆的雷管数量最多达到800多发;爆破效果良好,且未发生任何安全事故。通过将PHED-1型电子雷管与我国早期的电子雷管相比较,分析了PHED-1型电子雷管在改善爆破效果、减轻爆破振动、提高施工安全性、做好公共安全监管等方面具有的独特优势。PHED-1型电子雷管的以上优势和成功的应用案例,说明该电子雷管在露天深孔爆破中具有良好的应用前景。
The application of PHED-1 electronic detonator in open-pit deep hole blasting of the underground rock tunnel of Wengfu Phosphate Mine was introduced. After nearly two years of use, the accumulative use of the electronic detonator in the mines of Wengfu Phosphate Mine reached more than 40,000 rounds, and more than 2,000 tons of explosive was consumed. The number of detonators in a single detonation was up to more than 800. Its blasting effect was proven good, and no accident was recorded. By comparing PHED-1 electronic detonator with the early electronic detonator in China, the unique advantages of PHED-1 type electronic detonator in improving blasting effect, reducing blasting vibration, improving construction safety, and performing superiorly in public safety supervision were analyzed. The above advantages and successful application cases of PHED-1 electronic detonator indicate that the electronic detonator has a good application prospect in open-pit deep hole blasting.
