摘　　要：针对危机矿山及老矿山深部找矿预测的问题,以云南省曲靖市会泽铅锌矿矿山厂矿段矿体为例,基于对区域地质背景、成矿作用以及各类控矿因素的研究,结合所建立的地质数据库以及三维矿体模型,利用MapGIS实现了对研究区矿体厚度以及矿化强度空间变化规律的分析研究,包括分析其规律性及方向性。最后综合两种空间分析圈定出了3个隐伏矿体预测靶区,靶区Ⅰ标高为1 600m至1 400m中段附近,靶区Ⅱ标高为1 400m至1 200m附近,靶区Ⅲ标高为1 570m至1 350m附近,均处于矿山厂逆断层上盘,赋存于摆佐组中;对矿体深部实现了初步预测。In view of the problem of deep prospecting prediction in crisis mines and old mines,this paper takes an example of Kuangshanchang ore-block of Huize lead-zinc mine in Qujing City,Yunnan Province.Based on regional geological background,mineralization and all kinds of research about ore-controlling factors,combined with the established geological database and ore body model,it realized that the analysis to research ore body thickness and the space changing rule of the intensity of mineralization in the study area by MapGIS,including the analysis of regularity and direction.Finally,the article combined the two spatial analysis to delineate three target forecast concealed ore body that elevation of target I is near 1 600mto1 400 m,elevation of targetⅡ is near 1 400 mto 1 200 mand elevation of targetⅢ is 1 570 mto 1 350 m.They are all up the Kuangshanchang reverse fault and occur in Baizuo group,achieving apreliminary prediction for deep ore body.
