Standardized Entry and Three-Dimensional Visualization Management of Basic Data for Coal Reserves

Abstract

With the continuous advancement of intelligent coal mine construction and refined resource management, coal reserve management has imposed higher requirements on the standardized organization of basic data, intuitive expression of spatial objects, rapid query of results, and traceability of management processes. In response to problems such as diverse data sources, inconsistent formats, and the dispersed management of two-dimensional drawings and statistical results, this paper constructs a workflow for standardized data entry and three-dimensional visualization management around data sorting, standardized database entry, two-dimensional drawing extraction, three-dimensional visual expression, and result version management in reserve management. Taking boreholes, boundaries, faults, protective coal pillars, reserve blocks, and parameter tables as the main data objects, the workflow realizes the standardized organization of basic coal reserve data through field unification, coordinate checking, object classification, file archiving, attribute association, and version recording. On this basis, functional modules such as two-dimensional drawing preview, three-dimensional model browsing, result query, and version tracking are designed to form a management loop from data preparation to result display. Application using coal mine data shows that the proposed workflow can improve the standardization and traceability of reserve data management, enhance the spatial expression capability of reserve management objects, and provide basic support for the informatization of coal reserve management.
