煤炭地质钻孔数据集
收藏资源简介：
企业通过地质岩芯钻探施工方法，获取地下岩层与煤层的实体样本及钻孔空间结构数据，建立可供直接观测与分析的地下实物原始库。通过现场地质编录与观测方法，对岩芯箱中的实体样本进行即时鉴定、测量与记录，获取以深度序列为核心的标准化数据，包括地层分层深度与厚度数据、岩性定名与特征描述信息（如颜色、结构、构造、矿物成分、化石等）、以及煤层专项信息（宏观结构、夹矸的层数-岩性-厚度、总厚与可采厚度）。这些数据共同构成了钻孔的现场观测原始数据库。通过钻孔工程记录与测量方法，获取钻孔本身的身份与状态数据，包括钻孔坐标、孔口标高、开孔与终孔日期、不同井段的直径、套管下深等。这些数据建立了钻孔工程属性与空间定位的基础信息库。 通过标准化地质制图与信息集成方法，将上述来自实物样本、现场观测和工程记录的三大类原始数据库，按照统一的行业规范进行系统性整合与处理。该过程首先依据统一的行业数据规范与编码体系，分别对实物样本描述、现场观测记录及工程属性信息进行结构化整理，确保各类数据在命名、单位、分类上保持一致；进而通过深度校准与空间配准，建立不同数据库之间基于钻孔编号、钻孔坐标、钻孔深度的严格对应关系；在此基础上，利用统一的图例、图式与符号标准，将整合后的数据转换为规范的图形元素，进行综合关联与可视化表达，从而建立一份完整、直观、可存档与检索的钻孔柱状图。该图库系统地保存并呈现了通过钻孔直接揭露的、未经后期复杂解释的原始地质情况，是后续一切煤矿资源评价与工程设计赖以立足的客观证据基础。
Enterprises obtain physical specimens of underground rock formations and coal seams, as well as spatial structure data of boreholes, through geological core drilling construction methods, and establish an original underground physical specimen repository that allows direct observation and analysis. Using field geological logging and observation methods, on-site identification, measurement and recording are conducted for physical specimens in core boxes, to obtain standardized data centered on depth sequences, including stratigraphic bed depth and thickness data, lithologic designations and characteristic description information (such as color, structure, texture, mineral composition, fossils, etc.), as well as coal seam-specific information (macroscopic structure, number-lithology-thickness of gangue inclusions, total thickness and minable thickness). These data collectively form the original on-site observation database of boreholes. Through borehole engineering recording and measurement methods, identity and status data of the boreholes themselves are obtained, including borehole coordinates, collar elevation, spud-in and completion dates, diameters of different borehole sections, casing setting depth, etc. These data establish a basic information database for borehole engineering attributes and spatial positioning. Through standardized geological mapping and information integration methods, the three categories of original databases mentioned above (from physical specimens, on-site observations and engineering records) are systematically integrated and processed in accordance with unified industry specifications. This process first conducts structured organization of physical specimen descriptions, on-site observation records and engineering attribute information respectively based on unified industry data specifications and coding systems, to ensure consistency in naming, units and classification of all types of data; then establishes strict correspondence between different databases based on borehole number, borehole coordinates and borehole depth through depth calibration and spatial registration; on this basis, uses unified standards for legends, diagrams and symbols to convert the integrated data into standardized graphic elements, conducts comprehensive association and visual expression, thereby establishing a complete, intuitive, archivable and retrievable borehole log. This borehole log repository systematically preserves and presents the original geological conditions directly exposed by boreholes without complex later interpretation, which is the objective evidence foundation for all subsequent coal resource assessment and engineering design.
