摘　　要：21世纪地球科学的“第四范式”与第四工业时代以及5G+智能通信为矿业开发与环境防护的关联研究提供了新契机。以地球动力学背景、成矿过程、定量评价“三位一体”的地学理论为基础,以栾川矿集区为例,运用地学大数据(多维多尺度的地质、地球物理、地球化学、高光谱与高分辨率遥感(多时相)以及实时矿业等数据)的深层次人工智能挖掘和三维/四维多学科多参数多尺度建模技术平台,开展矿集区至矿床多尺度的三维地质模型、成矿过程模型和定量勘查模型构建及其资源的定量预测评价,旨在实现数字矿山的高精度三维地质(岩石、构造、水文、土壤等)环境保护和资源综合开发利用的动态评价,为研究区矿产资源与矿山环境可持续发展提供科学依据。研究结果概述如下:(1)地球科学大数据关联矿集区资源预测评价。利用三维地质建模、地质-地球物理正反演解译、地球化学与遥感等地学数据深层次挖掘,结合自主研发GeoCube2.0集成软件,实现了栾川矿集区(500 km^(2),深部2.5 km)的深部靶区优选和矿产资源综合评价,Mo资源量650万t,W资源量150万t,Pb-Zn-Ag累计具有500万t资源量。(2)地质、矿床与勘探的三维地学建模关联矿山环境。南泥湖—三道庄—上房矿山露采场与骆驼山深部巷道勘探与采矿的资料表明,区域NW向的斑岩夕卡岩型矿床与矿体与地下水空间关联度不高,而成矿期后通常具有张性或张扭性特征的NE向断裂是地下水运移的通道;在NW向Pb-Zn矿床地段具有显著淋滤特征的次生金属矿产出,浅表的氧化铅锌矿与锰铁矿伴生孔雀石化、铅华等水蚀作用;高海拔Pb-Zn矿区且NE向断裂构造发育的冷水、百炉沟地段存在地下水污染风险。(3)智慧矿山构建关联资源环境评价与决策。在大型矿山建立三维地质模型并关联矿区古采洞、露采场与深部巷道工程,实现矿业合�The“fourth paradigm”of the 21 st century Earth Science,the fourth industrial era and the 5G+intelligent communication provide mineral researchers with a new opportunity to study the relationship between mining development and environmental protection.This study is based on the geoscientific theory that emphasizes the connections between geodynamic background,metallogenic process and quantitative assessment.Taking the Luanchuan mining district as an example,using geoscience big data(multi-dimensional,multi-scale geological,geophysical,geochemical,multi-temporal hyperspectral/high-resolution remote sensing,real-time mining data)platform,including deep artificial intelligence mining technology as well as 3D/4D multi-disciplinary,multi-parameter,multi-scale modeling technology,we constructed a 3D geological model,a metallogenic process model and a quantitative exploration model at the district and deposit scales,and performed quantitative prediction and assessment of the related mineral resources.The aim was to achieve dynamic assessment of high-precision 3D geo-environmental(rock,structure,hydrology,soil,etc.)protection and comprehensive development and utilization of resources in digital mines,so as to provide a scientific basis for the sustainable mineral resource development in the study area.The research results are summarized in three main aspects:(1)Application of geoscience big data in resource prediction and assessment of district.By mining geoscience big data such as 3D geological modeling,geological and geophysical forward/backward interpretation,geochemical and remote sensing data mining,etc.,with use of the self-developed GeoCube2.0 software,deep target optimization and comprehensive mineral resources assessment were achieved for the Luanchuan mining district(500 km^(2)in area,2.5 km deep).The predicted Mo,W and Pb-Zn-Ag resources in the mining district were 6.5,1.5 and 5 million tons,respectively.(2)Three-dimensional geologic modeling of ore deposit and mineral exploration related to mining environm
