滇西北雪鸡坪铜矿床产于印支晚期石英二长闪长玢岩-石英闪长玢岩-石英二长斑岩复式侵入体内,为经历了多阶段热液成矿作用的斑岩型铜矿床.综合前人从区域地质背景、矿床地质特征、含矿岩体地球化学及成岩成矿时代等多方面的研究发现,针对雪鸡坪铜矿区经济效益的研究相对不足.利用雪鸡坪铜矿区生产勘探的相关数据资料,对勘查区资源开发经济指标参数进行概略评价,并在此基础上采用敏感性模糊分析法探讨了影响矿区生产勘探经济效益的综合敏感性因素.结果表明:价格因素是影响矿区经济效益的综合敏感因素,其次是成本因素、投资因素和规模因素.同时,分析认为从目前圈定的主矿体KT1和KT2的资源储量看,勘查区域的资源开发具有良好的经济效益.
The Xuejiping Copper Deposit occurs in the complex intrusion of the late Indosinian quartz diorite porphyry-quartz diorite porphyry-quartz monzonitic porphyry in Northwest Yunnan.It is a porphyry copper deposit,which has experienced many stages of hydrothermal mineralization.Based on precedent research achievements,such as the study of the regional geological background,the geological characteristics of the deposit,the ore bearing rock geochemistry and the metallogenic epoch,it is found that there are relatively insufficient research carried out on the economic benefits of Xuejiping Copper Mining District.According to the productive prospecting on Xuejiping Copper Mine in Northwest Yunnan,briefly economic benefits evaluation of the indicator parameters is conducted in the prospecting area.Based on that,sensitivity fuzzy analysis is used to discuss the comprehensive sensitive factors influencing the economic benefits of the productive prospecting in the mining area.The results show that price change is the primary comprehensive sensitive factor influencing economic benefits of the mining area,and next to it are the cost,investment and scale factors.At the same time,the analysis considers that resource development of the prospecting area has good economic benefits in light of the resource reserves of KT1 and KT2,which are currently delineated as the main orebodies.
