【摘要】 在参考大量资料的基础上,针对安庆铜矿深部大直径深孔法开采的稳定性进行研究．经计算分析,认为安庆铜矿深部典型矿岩具有弱～中等程度的岩爆倾向性．运用块体理论分析结构面产状对深部开采稳定性的影响；通过对工程岩体的评价,认为安庆铜矿深部岩体质量级别为Ⅲ级．通过数值模拟得出合理的开采顺序；为减小爆破振动提出合理的爆破方式．更多还原

【Abstract】 This paper researches the stability of the anqing copper mine deep mining on the base of large data. The paper considers it has the feeble or middle rockbursts proneness of anqing copper mine by computing and analyzing.The paper analyses the deep exploitation stability that discontinuities form impacts on by the block theory;it isⅢrock-grade through the engineering rock masses evaluation.The paper gets a reasonable mining sequence by the numerical simulation and a reasonable blasting method in order to reduce the blasting vibrancy.更多还原
