无梯粘性粒状铵油炸药在硬岩采矿中的应用

摘要

无梯粘性粒状铵油炸药由多孔粒状硝铵、柴油、乳胶基体、改性铵油炸药混制而成.该新型炸药加工和使用安全可靠,接近零氧平衡,所产生的有毒有害气体少,炸药能量利用率高,适应风动机械装药的流散性好,返粉率低,防潮性能强、爆破效果好.无梯粘性粒状铵油炸药通过在柿竹园硬岩采矿中的应用表明,在采矿工艺和爆破参数不变的条件下,完全能够取代含梯炸药.%The non-TNT glutinous granular ANFO is mixed with four materials, porous granular ammonium nitrate, diesel, emulsion substance and modified ANFO. The new type explosive is reliable and safe to be processed and used. because of reaching near-zero oxygen balance,so the toxic and harmful gases is less and the utilization of explosive energy is high,and the rate of return powder is low,which can adapt wind-motive mechanical loading,and has fine flow performance and strong moisture resistant, as well as excellent blasting effect. The application of non-TNT glutinous granular ANFO in Shizhuyuan hard rock mining illustrate that the new type explosive can completely to replace with TNT contained explosives under the same conditions of mining technology and blasting parameters.
