煤系共伴生矿产定义内涵及分类

Definition Connotation and Classification of Coal Associated Minerals

摘要:

含煤岩系中存在着多种矿产和元素，统称为煤的共伴生矿产。然而,煤的共生矿产与伴生矿产明显不同,主要体现在成矿过程、赋存方式及其后期开采形式等方面，至今二者概念较为模糊，需要进一步区分。通过详细分析了煤共生、伴生矿产的特征，根据矿产在煤层中的赋存状态、存在位置及与煤的关系，认为煤的伴生矿产包括煤层气、煤成气、镓、铀、锗、钒等，共生矿产包括页岩气等，而油页岩、粘土与高岭土则既是伴生矿产也是共生矿产。在此基础上，该文提出了煤的共生、伴生矿产分类方案，对煤系矿产资源的勘探与开发有着重要的指导意义。

Abstract:

There are many minerals and elements in coal-bearing rock series. It is generally called associated mineral resources. But syngenetic mineral resources and associated mineral resources in coal are different. It mainly reflected in mineralization process, occurrence forms and mining forms in late production period. So far, the concept of syngenetic mineral resources and associated mineral resources are not clear. It needs to be further distinguished. In this paper, through detailed analysis on characteristics of syngenetic mineral resources and associated mineral resources, according to the occurrence, position and relationship with the coal minerals, it is regarded that the associated minerals of coal include bed methane, coal gas, gallium, uranium, germanium, vanadium, etc, while the syngenetic minerals include shale gas and others. Oil shale, clay and kaolin are not only associated minerals, but also syngenetic minerals. On these basis, the scheme for distinguishing syngenetic or associated minerals of coal has been put forward. It has important guiding significance for the coal resources exploration and development.
