摘　　要：随着某铜矿的不断开采,现开拓水平已至深部开采范畴,原开采水平相关参数需要进一步调整,以适应本阶段开采。针对爆破参数选择问题,采取爆破漏斗试验,分析试验效果,统计块度分布,比对漏斗形状。根据试验获得的参数,初步掌握岩石可爆性性质,并根据类似工程经验比对,初步制定了建议性的爆破参数,可为类似工程提供参考。With the continuous mining of a copper mine,the exploration level has reached the deep mining category,and the parameters related to the original mining level need to be further adjusted to adapt to the mining stage.Aiming at the problem of selecting blasting parameters,the blasting funnel test was carried out to analyze the test effect,and the distribution of lumpiness was counted and compared with the shape of the funnel.According to the parameters obtained from the test,the blasting properties of rock are preliminarily mastered,and the recommended blasting parameters are preliminarily formulated according to the experience comparison of similar projects,which can provide reference for similar projects.
