我矿是一个开采了500多年的老矿。矿床属中—高温热液充填交代类型,赋存于中上泥盆纪灰岩、花岗岩接触带的石灰岩、大理岩中。矿体倾角一般为60—70度,少数矿体倾角小于50度。矿体厚度由几公分至几米不等,多在0.5—4米之间,在矿体膨大部分超过4米,有的达10多米。矿体走向由数米到100多米不等。矿体延深一般大于走向长度,两者之比为3:2。矿体数目多,规模小,分
Mine is a mine that has been mined for more than 500 years. The deposit belongs to medium-high hydrothermal filling type, and occurs in the limestone and marble of the Middle-Upper Devonian limestone and granite contact zone. Ore body inclination is generally 60-70 degrees, a few ore body inclination less than 50 degrees. Ore thickness from a few centimeters to several meters, mostly between 0.5-4 meters, enlarged part of the ore body more than 4 meters, some of more than 10 meters. The ore body goes from several meters to more than 100 meters. Depth of the ore body is generally greater than the length of the strike, the ratio between the two is 3: 2. The number of ore bodies, small size, points
