随着露天开采技术的发展,深孔爆破规模不断增大。目前,露天矿一次爆破炸药量为20～30吨,有时达100～150吨。在这种情况下,炮孔的可靠和有效起爆,对于保证爆破安全,提高炸药能量利用率,具有重要意义。一、现代矿用炸药的一些特点现代矿用炸药,主要是以低感度炸药硝酸铵为基本成分的硝铵类混合炸药。从起爆的角度来说,它的一些特点值得重视。
With the development of open pit mining technology, the scale of deep-hole blasting continues to increase. At present, the amount of explosives explosively exploded in open-pit mines is 20-30 tons, sometimes up to 100-150 tons. In this case, the reliable and effective detonation of the blast hole is of great significance for ensuring the blasting safety and improving the energy utilization rate of the explosive. First, some characteristics of modern mining explosives Modern mining explosives, mainly low-explosive explosives ammonium nitrate as the basic component of ammonium nitrate hybrid explosives. From the detonation point of view, some of its features deserve attention.
