横田矿山位于日本福岛县大沼郡金山町横田,距会津若松市44公里。横田矿山由本山、浜子、钝子三个矿床组成,前两者又分为上部矿体和下部矿体。这些矿体均埋藏较浅,统称为浅部矿体。横田矿山自1955年开始工作,至1967年为止,勘探和开采工作只局限于这些浅部矿体。自1969年以后,经过三年的深部勘探工作,在原有浅部矿体的下部,即在200～400米深度内,发现了新的矿体(深部矿体),仅铜矿 Yokota Mine is located in Yokota, Onuma-gun, Kusuma-machi, Fukushima Prefecture, Japan, 44 km from Aizuwakamatsu City. Yokota mine by the mountain, Hamako, blunt son of three deposits, the former two are divided into the upper orebody and the lower orebody. These ore bodies are buried shallow, collectively referred to as shallow ore body. Yokota mine began its work in 1955 and by 1967, exploration and mining work was confined to these shallow ore bodies. Since 1969, after three years of deep exploration work, new ore bodies (deep ore bodies) have been found in the lower part of the original shallow ore body, that is, at a depth of 200-400 m. Only copper ore
