摘　　要：铜街-曼家寨矿段是都龙矿区主要的生产矿山。在该矿段露采场中-西部,似层状锡锌主矿体的旁侧常产出小而富的脉状、透镜状锌铜矿体。此类矿体有的曾误作为"废石"排放,造成了资源浪费。在对矿区控矿因素分析的基础上,认为成矿是以燕山晚期岩浆热液为主导,矿体受深部隐伏花岗岩、南北向层间剥离断裂系及大理岩-片岩互层带等因素复合控制。结合找矿勘查、矿山生产和科研资料,依据隐伏岩体温度场数值模拟总结了找矿模式,指导矿山剥采区盲矿体预测。在圈定的两个靶区内,经浅表工程验证取得了较好的找矿效果,减少了矿石流失、提高了资源利用率、增加了经济效益。Tongjie-Manjiazhai ore domain is the most important ore domain in Dulong Mine. In the middle to western parts of this domain, the vein and lentoid smaller and richer Zn-Cu ore-bodies had been found around these stratoid Sn-Zn major ore-bodies. Some of them had been discharged as barren rocks or wasted resources in some degrees. Based on analysis of ore-controlling factors, it suggests that later Yanshanian magmatic hydrothermal should be the key to ore-forming. Concealed granites, N-S stripping faults, and inter-beds of marble and schist play controlling factors to ore-bodies in different degrees. Combined with ore prospection, mine production and research works, the prospection model on the basis of temperature field related to the concealed granites, has been provided for guiding the blind ore-bodies forecast. Preferable ore finding effects have been obtained through the shallow and surface exploration in the two target sections, in order to reducing the ore waste, enhancing the resources availability and increasing the economic benefit.
