对四川马边地区磷-萤石-铅锌-铜多矿种多空间勘查开发工作的思考

Thoughts on multi-minerals and multi-space geological prospecting work of phosphorus—fluorite—lead—zinc—copper in Mabian area,Sichuan Province

马边地区的磷矿资源储量丰富,以往的找矿工作中在沉积型磷矿勘查方面取得了显著的找矿成果。马边地区的磷矿矿业权地块有17处,开采或勘查矿种均为磷矿,只有3处采矿权地块附加开采铅锌矿,1处采矿权地块附加开采萤石矿,马边地区的矿产勘查开发呈现出矿种单一、空间狭窄的局面。基于近年来的找矿成果,建议构建马边地区磷—萤石—铅锌—铜多矿种多空间勘查开发新格局,部署以沉积型磷矿、热液型萤石—铅锌矿、砂岩型铜矿为主攻方向的综合找矿工作,主要包括在已有矿山上部及深部开展增储上产勘查工作、空白区的综合找矿工作及相应的科技创新工作,力争为新一轮找矿突破战略行动产出实效,为保障我国关键矿产资源供给安全发挥重要作用。

The reserves of phosphate rock resources are abundant in the Mabian area.In the previous prospecting work,remarkable prospecting results have been achieved in the exploration of sedimentary phosphate rock.There are 17 mining rights of phosphate rock in the Mabian area.The mining or exploration minerals are all phosphate rock.Only 3 mining rights are attached to the mining of lead—zinc ore,and 1 mining right is attached to the mining of fluorite ore.The mineral exploration and development in the Mabian area presents a situation of single mineral species and narrow space.Based on the prospecting results in recent years,it is suggested to construct a new pattern of multi-space exploration and development of phosphorus—fluorite—lead—zinc—copper multi-minerals in Mabian area,and to deploy comprehensive prospecting work with sedimentary phosphorus ore,hydrothermal fluorite—lead—zinc ore and sandstone-type copper ore as the main direction,mainly including the exploration of increasing reserves and production in the upper and deep parts of the existing mines,the comprehensive prospecting work in the blank area and the corresponding scientific and technological innovation work,so as to strive to produce actual results for the new round of strategic action of prospecting breakthrough and play an important role in ensuring the supply security of key mineral resources in China.
