点评:创新是企业发展的核心竞争力。对于紫金矿业而言,科技创新尤为重要。20多年来,紫金矿业所获得的资源不是低品位,就是难选冶。为破解这一发展瓶颈,紫金矿业通过一系列技术创新和管理创新,形成了以“低品位、难处理矿产资源综合回收利用及大规模工程化开发”、“湿法冶金”以及“地质勘查”为代表的三大行业领先的核心技术,及时解决了制约我国有色金属工业发展的重大技术难题,为我国低品位、难处理金、铜矿资源的综合利用和产业升级提交了“紫金方案”,同时也为新时代矿业转型升级贡献了“紫金智慧”。

2.我国首台悬臂式撑靴掘进机试运行

EBZ85CXINGXUANBEISHICHENGXUEJUEJINJIZAIYANGMEIERKUANGTOURUSHIYUNXING,ZHEIYESHIMUQIANWOGUOZAIDUANMIANZUIXIAODEJUEJINXIANGDAOZHONGSHIYONGDESHOUTAIGAILEIXINGJUEJINSHEBEI。ZUOWEIWOGUOSHOUTAICHENGXUESHIDUNGOUJICHANPIN,EBZ85CXINGXUANBEISHICHENGXUEJUEJINJITONGSHIYESHIMUQIANSHIJIESHANGLINGXIANDEJIEGEMIANXIAO、ANQUANGAOXIAODEKUANGYONGJUEJINSHEBEI。GAISHEBEIYOULIAONINGZHONGDUNJITUANHEDEGUOHAIRUIKEGONGSILIANHESHEJIYANFA、ZHIZAO,QIZHUYAOTEDIANSHISHIXIANJUE、MAO、YUNPINGXINGZUOYE,ZHUYAOSHIYONGYUMEIKUANGJINGXIAMATIXINGJIEMIANXIAODUANMIANYANXIANGKUAISUJUEJIN。

点评:传统的悬臂式掘进机仅能截割巷道部分断面,要破碎全断面岩石,还需要多次上下、左右连续移动截割头来完成工作。而悬臂式撑靴掘进机则有效解决了这些难题——通过减少巷道断面,加快掘进速度,降低掘进、支护成本,减少出矸量,降低洗选、环保成本。悬臂式撑靴掘进机项目是阳煤集团重点科研项目之一。2017年11月,该掘进机在阳煤二矿井下安装完成,应用于8号煤13采区21306综采工作面高抽巷施工,魅力尽显——在满足通风要求的前提下,巷道断面小了,掘进速度大幅加快。

3.我国选矿生产执行系统技术取得重大进步

点评:在采矿选矿复杂环境的条件下,工业现场执行系统由于其复杂工况以及高级别安全要求,实现自动化和智能化难度较大。而随着我国在物联网技术研发、标准研制、产业培育等方面的快速发展,应用物联网技术优化提高复杂工况的工业制造能力和水平成为产业升级换代的一个突破口。用户报告是最有力的说明——采用该选矿生产执行系统技术,金属回收率提高了1.04%,综合能效提高1.23%。

4.我国海上高温高压钻完井技术体系跻身世界前列

点评:我国南海地处欧亚、太平洋和印澳三大板块交汇处,与美国墨西哥湾、英国北海并称全球三大海上高温高压海区。但相比其他两个区,我国南海的温度、压力更高,是名副其实的“大炼炉”。而这个大炼炉里蕴藏着近15万亿立方米的天然气,约占南海总资源量的1/3,其天然气勘探也成为全球油气行业内公认的世界级难题。从成矿理论创新到高温高压钻完井关键技术突破,再到海上高温高压安全钻井全套技术研发,我国通过几十年的努力,成为全球第二个具备独立开发海上高温高压油气能力的国家。值得一提的是,“南海高温高压钻完井关键技术及工业化应用”还获2017年度国家科学技术进步奖一等奖,并在海外高温高压区块应用成功。

5.纳滤技术首次用于国内冶金矿山

点评:纳滤技术是一种新型膜分离技术,介于超滤和反渗透之间,可以高效截留水中的多价盐和有机污染物,对单价、多价离子混合体系具有很好的选择分离特性。与传统的反渗透技术相比,纳滤的操作压力更低,相对更节能。河钢矿业通过此项技术处理完的清洁水水质优于该矿周边地区使用的地下水,稍加投资对其进行简单处理即可用于饮用。在河钢集团绿色制造、绿色产业、绿色产品、绿色采购、绿色物流、绿色矿山“六位一体”布局里,河钢矿业通过制度完善、体系创新等演绎着新时代矿山绿色发展的新篇章。

6.我国建造的先进深海采矿船出坞下水

点评:拜耳法是一种工业上广泛使用的从铝土矿生产氧化铝的化工过程,是100多年来生产氧化铝的主流方法,至今也是最优秀、最节能、工艺设备最简单、最环保的方法,但收率偏低是其最大缺陷。而增值拜耳法的颠覆性突破,在不大幅增加成本的基础上,极大地提高了经济效益和社会效益,将改变世界铝产业的格局,带来革命性突破。对此,有专家认为,由于该技术的突破,目前我国高硅高铝矿拜耳法不能适用的现状有望得到突破性改变,将对我国铝产业原料给以极大支撑。并且,该技术在改造传统氧化铝产业、促进循环经济发展、节能减排、高效生产环保等发面具有重大意义。

9.云南研发国内最大柱浮选选矿技术
