Research Of Multi-Scale3D Stratum Data Model In Mine

Mine3D stratum model is the main components of the3DGIS and Digital Minetechnology, and one of the key issues in the current research of Digital Mine. Theresearch results have the great significance for the basic research on the geology,mineral resources exploration, mining resource efficient and safe and sustainabledevelopment of mining enterprises. In this paper, as a guide of mining geology theoryand geography information theory, the methods and process of establishing thethree-dimensional geological model based on drilling data are researched, and advancean object-oriented multi-scale three-dimensional geological data model of mining toachieve a multi-scale three-dimensional model. The main fruits of study are showed asfollow:(1) Based on the theory of mine geological modeling, the mine geological objects,geological features and the source and characteristics of the geological data inthree-dimensional visualization are analyzed; Research and analysis the existing3Ddata models and geological modeling technology, and the advantages and disadvantagesof each model were compared with three-dimensional data model which provides atheoretical basis and method of support for the establishment and implementation ofthree-dimensional coal mine geological modeling;(2) Under the guidance of stratigraphy theory,both the space characteristics andrelationships of the stratum in the study area are analyzed and researched; Based on theidea of the stratigraphy into strata to establish strata system and the multi-scale featuresof mining, the volume is divided into single volume and multi-volume, creating anobject-oriented multi-scale three-dimensional geological data model of mining toexpress the features of the spatial structure and properties in this paper;(3) Based on the study of three-dimensional data model and data structures, aimedat the widely used for drilling geological data, the methods and process of establishing athree-dimensional geological model based on drilling data are researched; Thethree-dimensional data model and the methods of the three-dimensional geologicalmodel were carried out the application based on the data of coal mine geological exploration, and achieve a multi-scale three-dimensional model.
