某铜矿是老矿山之一,过去地来投入了自然电场法,效果不佳。1963年在该矿坑内做了自然电场法试验,取得了一定的效果,为寻找深部盲矿体提供了线索。某矿坑垂直深度65—350米,矿体位于花岗岩凹部的矽卡岩体中。围岩为白云质大理岩,个别地区夹有角岩。岩墙较发育,主要为石英斑岩、霏细岩等。矿 A copper mine is one of the old mines, in the past to put into the natural electric field method, the effect is not good. In 1963 in the pit made a natural electric field test, and achieved some results, to find a clue for the deep blind ore body. A pit depth of 65-350 meters, the ore body is located in the granite hollow skarn body. Surrounding rocks are dolomitic marble, horn sand in some areas. Rock wall more developed, mainly quartz porphyry, felite and other rocks. mine
