普通爆破方法用于光爆粗探吴毅（金河磷矿）标准光面爆破其理论建立在光爆孔同时起爆的基础上，故要求采用特制光爆炸药或光爆药卷；以及采用高爆速工业导爆索或高精度微差雷管等特殊爆破器材进行爆破作业。这对于确保理想外观质量无疑是必要的，但却使爆破工艺复杂化，爆...
Ordinary blasting method used in light burst crude exploration Wu Yi (Jinhe phosphate rock) standard smooth blast theory based on the simultaneous detonation of light burst on the basis of the hole, it requires the use of special light explosion or light burst drug roll; and the use of high Explosive speed industrial detonating cable or high precision micro differential detonators and other special blasting equipment for blasting operations. This is undoubtedly necessary to ensure the quality of the desired appearance, but it complicates the blasting process ...
