摘　　要：吉家洼金矿为熊耳山地区隐伏-半隐伏陡倾斜的小型金矿床。经16年矿山开发,矿山资源面临严重危机。笔者通过吉家洼金矿浅中部金矿床控矿特征和成矿富集规律的系统研究,认为各矿体纵向上严格受断裂构造控制,横向上各断裂带在标高625～670 m间相交复合成一条矿脉,通过深部资源潜力预测和少量深部工程验证,预计可获得金资源量3872 kg,表明吉家洼金矿深部具有较大找矿潜力,应及时开展深部找矿验证工作。这对熊耳山地区深部找矿及寻找隐伏-半隐伏矿具有重大指导意义。Jijiawa gold deposit is one of the concealed-half concealed steep sloping small gold deposits in the Xiongershan area. After 16 years mine development, resources face serious crisis. According to the system study on shallow-middle ore-control characteristics and enrichment mode of the deposit, the authors think the ore bodies controlled vertically by the faults, change into one ore body in elevation of 625 - 670 m. Through the deep resource potential prediction and a small amount of deep engineering verification, we can be expected to get gold resources of 3872 kg. It should be promptly developed in deep prospection, which has great significance for the Xiongershan area deep prospection and seeking for concealed-half concealed deposits.
