本网讯 6月14日，紫金矿业旗下采矿研究所自然崩落法研究团队在塞尔维亚紫金铜业成功完成地应力测试，为塞紫铜Jama斑岩矿实施大规模自然崩落法开采关键技术研究提供了关键理论依据。 加快推进自然崩落法科技应用与创新攻关，是紫金矿业实现未来五到十年战略目标的重要途径之一。其中，地应力测试作为工程岩体稳定性分析及工程设计的重要参数，对矿山采矿方法可行性分析、开采布局与关键技术参数确定、地压灾害防控等具有基础性意义。 2021年4月以来，紫金矿业采矿研究所在Jama矿埋深约500m处、井下-60m中段已成功实现地应力测试，改写了塞尔维亚往往借鉴欧洲地区侧压系数进行估测的历史，填补了塞尔维亚矿业工程在该领域的空白。 除塞紫铜Jama铜矿外，紫金矿业还将加快研究自然崩落法采矿在塞尔维亚丘卡卢-佩吉下部矿带斑岩铜矿、福建紫金山罗卜岭斑岩铜钼矿、黑龙江铜山斑岩铜矿应用的可行性，以实现大规模、低成本、高效益开...
