江西赣南地区是我国主要产钨地区,通称赣南钨矿。矿床为裂隙充填含钨石英脉矿,f=10～12;围岩为变质岩与花岗岩,岩质坚硬稳固,f=20～25。矿床产状基本上为急倾斜平行脉群矿,倾角一般为70～90°;脉幅平均为0.3～0.4米,最宽达6～8米,矿脉间距一般在10米左右。矿脉分枝复合,交替侧现较普遍。矿区岩石节理发育,断层、岩脉也较多。赣南钨矿的开采历史已有五十多年。解放前,采矿多在地表部分,为不规则的下向
Gannan in Jiangxi Province is a major tungsten producing region in China, commonly known as Gannan tungsten mine. The deposit is fissure filled tungsten-bearing quartz vein, f = 10 ~ 12; the surrounding rock is metamorphic and granite, rock hard and firm, f = 20 ~ 25. The occurrence of the deposit is basically a steeply inclined parallel vein group ore with a dip angle of 70 ~ 90 °. The average pulse amplitude is 0.3 ~ 0.4 meters and the widest is 6 ~ 8 meters. The veins spacing is generally about 10 meters. Vein branching compound, alternate side is more common. Mining rock joints developed, faults, dikes are also more. Gannan tungsten mining history of more than 50 years. Before the liberation, mining mostly in the surface part of the irregular downward direction
