摘　　要：针对以成品炸药改性加工制备爆炸焊接专用炸药的复杂工艺,提出并成功开发了一种"多孔粉状铵油冷混"新工艺,仅采用多孔粒状硝酸铵、密度调节剂和柴油3个组分,在国内外首次实现了金属板材爆炸复合加工专用炸药的现场混装,结合配套新型现场混装炸药车的研制,解决了粉状物料在混装车料仓中容易蓬料成拱、不易输送的工艺问题,实现了炸药配方及成套工艺技术的工业化应用。For complex technology preparing for welding dedicated explosives which is modified from finished explosives, a new process of ＂cool mixing of porous-powdered ANFO＂ was proposed and developed, in which only three compo- nents including porous granular ammonium nitrate, density regulator and diesel oil were used. Mobile manufacture unit （MMU） enabling on-site mixing metal sheet dedicated explosives cladding was achieved for the first time either domestical- ly or abroad. Combined with the new on-slte mixed explosives charging truck, the problem that powdery ammonium nitrate cannot transport well in the storage bin of the blend truck was solved, and the industrialized application of explosives formu- la and unitized technology was realized.
