- Scope
- This standard was compiled to adapt to the standardization of geological data. The purpose is to improve the simplification of core identification in many areas, the description content is not uniform enough, and the identification of certain signs is inaccurate, and to promote the improvement and unification of the description and identification level to fully obtain coal-bearing rocks. Various genetic analysis information in the series cores can lay the foundation for coal seam comparison and reconstruction of depositional environment, as well as further research on petrophysical properties that are closely related to mining technical conditions. This standard is divided into lithology part, sedimentary structure part, petrogenesis type part and coal rock and coal facies part. In order to be used by grassroots geologists for on-site comparison, it is mainly based on ancient hole core data of coal-bearing rock series, and Supplemented by a small amount of outcrop data.
