露天矿山无导爆索光面爆破技术的研究

Study on Smooth Surface Blasting Technology without Detonating Cord in Open-pit Mines

介绍了露天矿山边坡光面爆破的工作原理,无导爆索光面爆破主要参数的选择和无导爆索装药的施工方法。广东某矿山的应用实例显示,采用导爆管雷管替代导爆索的无导爆索光面爆破技术,能提高边坡的稳定性,确保边坡的成型质量,降低爆破成本,提高企业经济效益。

This paper introduces the working principle of smooth blasting on slope of open-pit mine,the selection of main parameters of smooth blasting without detonating cable and the construction method of charging without detonating cable.The application example of a mine in Guangdong province shows that the smooth blasting technology without detonating cord can improve the stability of the slope,ensure the forming quality of the slope,reduce the blasting cost and improve the economic benefit of the enterprise.
