硝銨炸藥由于炸燃溫度很高(与胶質炸藥比較),用引綫所生之火花难以使之燃燒爆炸。因此一般都用雷管激起炸藥爆炸。而火藥由于爆炸燃溫低,用引綫所生之火花可使之爆炸,火藥爆炸产生强力的冲击波,即使硝銨炸藥爆炸而代替了雷管的功能。根据这个原理,在砲眼底部装以硝銨炸藥,上部装火藥並插入引綫,再以泥堵塞砲眼爆跟。裝藥长度視砲眼深度、岩石性質和爆眼的質量而定。其中火藥部份的长度下得少于1公寸,否則,可能发生拒爆。火藥爆破时带动
Ammonium nitrate explosives have a high burning temperature (compared to colloidal explosives), making it difficult to burn and explode with sparks from the lead wires. Therefore, detonators are generally used to provoke explosive explosions. The gunpowder is low in ignition temperature, and can be exploded by sparks generated by the lead wire. The explosion of the gunpowder generates a powerful shock wave, even if the ammonium nitrate explosive explodes instead of the function of the detonator. According to this principle, ammonium nitrate explosives are installed at the bottom of the blasthole, the upper part is filled with gunpowder, and the lead is inserted, and then mud is used to block the explosion of the blasthole. The length of the charge depends on the depth of the blasthole, the nature of the rock, and the quality of the blasting. The length of the gunpowder part is less than 1cm. Otherwise, the explosion may occur. Driven by gunpowder blasting
