系统研究了夹皮沟地区二道沟、庙岭、大猪圈、下戏台和东坨腰子等矿床矿体和近矿围岩微量元素、矿石矿物组合和黄铁矿热电系数等的垂直变化特征，认为三者具有相互一致的变化规律，即：与热液金矿床通常的分带性相比，具有逆向分带的现象，这种特征被认为是多层次正常分带上下叠加的产物，反映夹皮沟地区金矿床在垂向上普遍存在着多个富集地段． 据此预测二道沟、庙岭、大猪圈、下戏台和东坨腰子等矿床在目前的开采深度下部仍有发现深部矿体的可能．
The vertical variations of trace elements, ore minerals assemblages and pyrite pyrites in the orebodies and nearby orebodies of the Erdaogou, Miaoling, Big Pig, Xiaoshidai and Dongtouzi, etc. in the Jiapigou area were systematically studied , That the three have consistent changes in the law, that is: compared with the normal zonation of hydrothermal gold deposits, with a reverse zoning phenomenon, this feature is considered to be multi-level normal zoning up and down the product of the superposition, reflecting The gold deposits in the Jiapigou area have many enrichment lots in the vertical direction. Based on this, it is predicted that there is still a possibility of discovering deep orebodies in the lower part of the present mining depth, such as Erdaogou, Miaoling, Big Pigs, Xiaxiotai and Toto Tuozi.
