巴润矿矿岩可爆性分区研究

摘要

This paper analyzes the defects of domestic and foreign rock classification of blastablity, and various factors affecting blasting result to meet to the needs of production in open pit mine. The concept and necessity of zoning of blasting in open-pit may be proposed. Mechanical properties of rock, rock mass joints, cracks are used as the technical indicators to determine the zoning of blastablity, the zoning mathematical model and criteria of zoning are made by gray clustering system theory. Zoning of the blastablity is used in BaRun mine blasting optimization; application results show that the zoning method is scientific, reasonable and practical.%本文分析了国内外岩石可爆性分级的缺陷及影响爆破效果的诸因素,根据露天矿山生产需要,提出了矿、岩体可爆性分区的概念及必要性.采用岩石力学特性,岩体节理、裂隙作为可爆性分区的技术指标,确定了露天矿岩体可爆性分区的准则.采用灰色系统决策理论,建立了各分区指标的数学模型.将爆破性分区应用于巴润矿爆破技术优化中,结果表明分区方法科学、合理、实用.
