摘要 露天矿山爆破粉尘含大量微细颗粒,严重污染采场环境。通过分析水雾除尘机理,自主设计并建立爆破粉尘测试系统,在高村铁矿进行水袋间隔装药结构与岩粉间隔装药结构的爆破粉尘对比试验,结果表明:采用水袋间隔装药,粉尘吸附效果较好,吸附率达到46.72%~51.20%;同时在改善破碎块度方面也优于岩粉间隔装药。水间隔装药降尘爆破技术在露天采矿以及非矿山领域的工程爆破中具有广阔的应用前景。

Abstract: Large amount of micro-sized particles is contained by blasting dust in open-pit mine, the environmental pollution of the stope is serious. Based on analyzing the water fog dust removal mechanism, the blasting dust test system is designed and established, the blasting dust comparative test of water bag interval charge structure and rock power interval charge structure in Gaocun iron mine is conducted, the results show that the dust adsorption effect of water bag interval charge structure is better than rock power interval charge structure, the dust adsorption rate is 46.72%~51.20%,besides that, the improving effects of the rock broken size of water bag interval charge structure is also superior to rock power interval charge structure. The study results of this paper further indicated that the blasting technique of water interval charge dust removing has good application prospect in the engineering blasting of open-pit mining and other industries.
