摘要
Abstract
Generally, conventional coal exploration results are shown based on two-dimensional maps, it is very difficult to express three-dimensional spatial distribution in direct and visual way. Based on borehole data, two-dimensional topographic and geologic map, coal seam bottom contour map and geologic exploration section map, this paper reconstructs spatial distribution of ground surface, coal seam, shape of main faults and temperature field. Based on geological data of multi-source, three-dimensional geological modeling results clearly show us coal seam shape features, coal accumulating scope and intensity of each sedimentary cycle, structural outline characteristics and underground temperature field characteristics. The results show that three-dimensional visualization technology with geological data of multi-source vividly reflects the morpho-logical characteristics of coal seam and other geological bodies, it also can effectively analyze the sequence of complex geological faults formed in the geological history and paleotectonic stress field characteristics. Therefore, it is a very effective means using three-dimensional geological modeling for the analysis of the deposition, structure and geological attribute field.关键词
