湘潭锰矿属于浅海沉积的原生碳酸锰矿床,由一个“V”字形复式向斜和一个单斜组成。矿体呈层状,产于震旦系下部黑色页岩中,现开采向斜构造部分。矿层倾角一般为15～30°,局部达50°以上。矿层厚度变化大,主要矿层最薄为0～0.5米,最厚达6米以上,平均2米左右。矿层地质构造异常复杂,褶皱断裂现象严重,断层呈纵横交错分布。由于构造复杂,矿层底板起伏较大,矿层重复交错,局部厚度增大或变薄拉断。沿断层和矿层底板凸起处,往往出现条带状的无矿带。本矿是内因火灾甚为严重的矿山,
The Xiangtan manganese ore belongs to the native marine carbonate deposit deposited in the shallow sea and is composed of a “V” -shaped compound syncline and a monocline. The ore body is stratified and is produced in the black shale in the lower part of the Sinian. The syncline structure is now exploited. The dip of the ore is generally 15 ~ 30 °, and the local area reaches more than 50 °. The thickness of the ore layer varies greatly. The thinnest main ore layer is 0 to 0.5 meters and the thickest is 6 meters or more, with an average of 2 meters. The geological structure of the ore body is extremely complicated, the folds and faults are serious, and the faults are criss-crossed in a crisscross pattern. Due to the complicated structure, the floor of the mine has a large fluctuation, the ore layers are repeatedly staggered, and the local thickness is increased or thinned. Banded along the fault and the floor of the bottom plate, there is often strip of non-ore belt. The mine is a very serious internal fire mines,
